Every industry has its own secret language. Startups might have the thickest slang dictionary of them all.
Walk into a pitch meeting, and you will hear about runway and burn, SAFEs and caps, ARR and NRR, TAM and SOM, often all in the same sentence. Some of it is genuinely useful shorthand. Some of it is jargon people use to sound smart – we do use a lot of it @ build3, ngl. Either way, if you are building, funding, joining, or just following startups, you need to speak the language.
This is the comprehensive version, with over 200 terms grouped by theme so you can easily find what you need. Beginners can start at the top. Anyone hunting for a specific fundraising or finance term can jump straight to that section. Where a simple formula clarifies the concept, it is included.
1. Foundations & Company Stages
Startup
A young company designed to grow fast. It is searching for a business model that can be repeated and scaled, usually around a new product or market. The ambition to grow quickly is what separates a startup from a small local business.
Small Business
A company built for steady, long-term income, not rapid growth. Think of a local bakery or a consulting firm. It is a great life path, but it is not a startup in the venture capital sense.
Lifestyle Business
A business built to support a founder’s desired lifestyle, not to conquer a market or get to a billion-dollar valuation. It prioritizes freedom and steady cash flow over hypergrowth.
Bootstrapping
Funding the company from personal savings and customer revenue instead of outside investors. Founders who bootstrap keep full ownership and control.
Founder / Co-founder
The person (or people) who start the company. Co-founders share the earliest risk and typically the largest pieces of the ownership pie.
Solopreneur
A founder who builds and runs a business alone, without co-founders or, often, employees.
Ideation
The very earliest phase of coming up with and shaping the business idea. This happens long before anything is built.
Validation
Testing whether real customers actually want and will pay for your solution, before you invest a ton of money building it. It is like asking people if they want a sandwich before you open a whole deli.
Proof of Concept (POC)
A small, internal test to see if an idea can actually be built and work technically. It is less about customer needs and more about checking if the technology is feasible.
MVP (Minimum Viable Product)
The simplest, most basic version of a product that delivers core value. You release it to learn from real users with the least effort. Think of it as a skateboard when your grand vision is a car. It still gets people from A to B.
Product-Market Fit (PMF)
The magical point where you have built something a specific market genuinely wants. Demand starts pulling the product forward on its own, like customers arriving without heavy advertising.
Pivot
A deliberate, structural change in strategy. It might be a new product, a new market, or a new business model. This happens after you learn the original plan is not working. It’s not a failure; it’s a course correction.
Traction
Measurable proof that the business is working. This could be growing users, revenue, engagement, or another meaningful signal that the flywheel is starting to spin.
Scalability
The ability to grow revenue much faster than costs. The goal is that serving 10 times the customers does not require 10 times the resources or people.
Unicorn
A privately held startup valued at $1 billion or more. They are called unicorns because they were once considered mythical and rare.
Decacorn
A private startup valued at $10 billion or more. Even rarer than a unicorn.
Soonicorn
A startup widely expected to reach unicorn status soon. It’s a future unicorn, if you will.
Zebra
A company that aims to be both profitable and purpose-driven. It is a deliberate contrast to the “grow at all costs” unicorn model. A zebra wants to heal wounds in the world, not just disrupt.
Centaur
A more practical milestone. A SaaS startup that reaches $100 million in Annual Recurring Revenue (ARR). It’s a celebration of steady, real growth over a flashy valuation.
Startup Studio / Venture Builder
An organization that builds multiple startups in-house. They supply the initial ideas, the first round of capital, and shared teams like HR and legal.
Incubator
A program that nurtures very early-stage ideas over a long, flexible timeline. It often provides workspace, mentorship, and a place to figure things out without a strict deadline.
Accelerator
A fixed-term, boot-camp-style program, typically a few months long. It offers mentorship, resources, and often a small seed investment in exchange for equity. The whole thing ends with a Demo Day. Think Y Combinator or Techstars.
Cohort
The group of startups that go through an accelerator program together in the same batch, or a group of users who sign up in the same period.
Demo Day
The big event at the end of an accelerator where all the startups pitch their companies to a room full of investors.
Pre-seed Stage
The “just an idea” stage. Funding often comes from the founders’ own pockets, friends, and family to build an MVP.
Seed Stage
The first official round of startup funding. The money is used to find product-market fit, get early users, and prove the concept works.
Early Stage
The phase where you have found product-market fit and are now scaling your first sales and marketing efforts. This usually covers Series A and B.
Growth Stage
The company is on a proven path and is now scaling aggressively. The focus is on capturing market share and fueling the fire. This covers Series C and beyond.
Late Stage
A large, established private company that is preparing for an exit, like an IPO. The rounds are big, and the company might already be profitable.
2. Fundraising & Investors
Angel Investor
A wealthy individual who invests their own personal money into very early-stage startups. They are often the first outside check a founder receives.
Venture Capital (VC)
A firm that raises a large pool of money from investors (called LPs) and invests it into high-growth startups in exchange for equity. They are aiming for huge returns that can pay back their whole fund.
Limited Partner (LP)
The investors who put money into a VC fund. These are the quiet backers. They are typically pension funds, university endowments, family offices, and very wealthy individuals.
General Partner (GP)
The people who run the VC fund. They make the final investment decisions, sit on startup boards, and manage the portfolio. They are the face of the firm.
Micro VC
A smaller venture fund that writes smaller checks, usually at the very earliest pre-seed and seed stages.
Family Office
A private company set up to manage the wealth and investments of a single, ultra-wealthy family. Some family offices invest directly in startups.
Syndicate
A group of individual investors who pool their money to back a deal together. One person, the syndicate lead, usually organizes it and takes a small cut of the profits.
Crowdfunding
Raising many small amounts of money from a large number of people, typically online. In equity crowdfunding, backers receive a tiny share of the company. In reward-based crowdfunding, they receive a product or a perk.
Venture Debt
A loan designed for startups, often those already backed by VCs. It is used to extend their runway without giving up more equity, like a supplement to a funding round.
Grant
Non-dilutive money, meaning free money. It comes from governments, foundations, or special programs. It does not have to be paid back, and it does not take any ownership.
Round
A single, focused fundraising event. Rounds are named by their stage: pre-seed, seed, then Series A, B, C, and so on as the company matures and raises larger amounts.
Bridge Round
A smaller, interim fundraise meant to “bridge” the company to its next major milestone or a larger round. Think of it as a financial bridge over a tricky gap.
Down Round
A new funding round raised at a lower valuation than the previous round. It is painful because it signals trouble and heavily dilutes existing owners.
Up Round
A new round raised at a higher valuation than the previous one. The goal every time.
Flat Round
A new round raised at the same valuation as the previous one. Not great, not terrible.
Lead Investor
The investor who sets the terms of a round, does the deepest homework on the company (due diligence), and usually puts in the single largest check. Other investors follow their lead.
Follow-on Investment
When an existing investor puts more money into a later round to maintain or grow their ownership stake. It is a vote of confidence.
Dry Powder
The committed capital a venture fund has raised but has not invested yet. It is their available firepower for new deals.
Deal Flow
The stream of potential investment opportunities an investor sees. A good investor needs strong deal flow to pick the best ones.
Due Diligence
The deep investigation an investor runs before committing money. They review your financials, legal contracts, technology, market, and team to make sure your story checks out.
Term Sheet
A non-binding document that outlines the key points of a proposed investment. It covers valuation, amount invested, and major rights, and it is the blueprint before the final, 100-page legal contracts.
Pitch Deck
The presentation founders use to tell their story to investors. It is usually a 10-15 slide summary covering the problem, solution, market, traction, team, and what you are asking for.
Data Room
A secure online folder, like a Google Drive or Dropbox, where you store all your company documents and share them with investors during due diligence.
Runway
How long your company can survive before it runs out of cash. Runway (months) = Cash in bank / Net monthly burn. It is your time left to fly.
Burn Rate
How fast your company is spending cash. Gross burn is your total monthly spending. Net burn is your total spending minus any revenue coming in.
Default Alive / Default Dead
A simple, blunt way to look at your business. On your current trajectory, will you reach profitability before running out of money? If yes, you are “default alive.” If no, you are “default dead.” The term was coined by Paul Graham.
Party Round
A seed or pre-seed round where a startup takes small checks from many different angels and micro-VCs, but with no single lead investor. It sounds fun, but it can mean no one is deeply committed to helping you when things get tough.
Sweat Equity
Ownership in a company that is earned through work and effort, not by putting in cash. It’s the value of your “sweat.”
3. Equity, Ownership & the Cap Table
Equity
Ownership in the company, represented by shares. If a company has 100 shares and you own 10, you have 10% equity.
Cap Table (Capitalization Table)
The master record of who owns what. It lists every shareholder (founders, investors, employees) and what percentage of the company they own.
Dilution
The shrinking of existing owners’ percentage stake when new shares are created and issued. If you own 10% of a pizza and a new person gets a slice, your percentage goes down, but the hope is the whole pizza is now much more valuable.
Anti-Dilution
A legal provision that protects certain investors. If the company later raises money at a lower price, their ownership is adjusted as if they paid that lower price, protecting them from losing value.
Pre-Money Valuation
The company’s value before a new investment comes in. It is the price tag on the company right now.
Post-Money Valuation
The company’s value after the new investment. Post-money = Pre-money + New investment. Simple as that.
Convertible Note
A short-term loan that converts into equity at a later funding round. It’s a way to delay setting a valuation. Instead of getting their money back, the investor gets shares later, usually with a discount or a valuation cap as a reward for investing early.
SAFE (Simple Agreement for Future Equity)
A simpler, more popular alternative to a convertible note, created by Y Combinator. Investors give you money now for the right to shares later. It is not a loan, so there is no interest, and it has a simpler legal structure.
KISS (Keep It Simple Security)
Another alternative to a SAFE, created by the accelerator 500 Startups. It comes in two flavors: a debt version (like a note) and an equity version (like a SAFE). The goal was the same: simpler early-stage paperwork.
Valuation Cap
The maximum company valuation at which a SAFE or note will convert into shares. It is a ceiling that protects early investors. If the company’s value skyrockets, they still convert as if it were at the lower cap, giving them more shares for their early faith.
Discount Rate
A percentage discount early SAFE or note investors get on the share price of a future round. It is another way to reward them for coming in early. A 20% discount means they buy shares for $0.80 when everyone else pays $1.00.
Vesting
Earning your equity slowly over time. It is a retention tool. The standard is a four-year schedule, meaning you have to stick around to earn your full ownership grant.
Cliff
The period at the start of a vesting schedule where you must stay before any equity vests. A one-year cliff is standard. If you leave before your first anniversary, you get nothing.
ESOP (Employee Stock Option Pool)
A block of shares set aside specifically to grant to employees. It is a way to give the team a sense of ownership and an incentive to help the company succeed.
Stock Options
The right, but not the obligation, to buy a company share at a fixed price (the strike price) in the future. If the company grows, you can buy cheap shares and sell them for more, making a profit.
Strike Price
The fixed, predetermined price at which an option holder can buy a share. It is set at the fair market value on the day the option is granted.
Common Stock
The type of stock founders and employees typically hold. It is the basic form of ownership. In a bad sale or liquidation, common stockholders are last in line to get paid.
Preferred Stock
The type of stock investors usually get. It comes with “preferred” treatment, meaning special rights, most importantly getting their money back before common stockholders in a sale.
Fully Diluted Shares
The total number of shares if everything convertible were turned into shares. This includes all options, warrants, and SAFEs. It is the true denominator for calculating real ownership percentages.
409A Valuation
An independent appraisal of what a private company’s common stock is worth. This is a US requirement to set a legal strike price for options, so the IRS doesn’t come after you.
Founder Shares
The equity founders grant themselves at the very beginning when they incorporate the company. This is usually common stock and is subject to vesting.
Phantom Stock
A cash bonus plan, not real equity. A company promises an employee a cash payout equal to the value of a certain number of shares at a future date. The employee never owns actual shares or gets voting rights.
4. Deal Terms & Term Sheet Mechanics
Liquidation Preference
The rule that determines who gets paid first, and how much, when a company is sold. A “1x preference” means the investor gets their original investment back before anyone else sees a cent. It is downside protection for investors.
Participating Preferred
A stronger, investor-favorable right. The investor first gets their liquidation preference back and then also shares in the remaining money with everyone else. This is known as “double dipping.”
Non-Participating Preferred
The more founder-friendly version. The investor has a choice: either get their liquidation preference back, or convert their preferred stock to common stock and share the money equally with everyone. They cannot do both.
Pari Passu
A Latin term meaning “on equal footing.” In a deal, it means all investors in a group have equal rights and are not structurally senior to each other.
Pro Rata Rights
The right for an existing investor to invest more money in future rounds just to maintain their current ownership percentage. It stops them from being diluted.
Drag-Along Rights
A clause that lets a majority of shareholders force the minority shareholders to join in on a sale of the company. This ensures a few small holdouts cannot block a great deal for everyone else.
Tag-Along Rights
The opposite, protecting the minority. If a majority shareholder sells their stake to a buyer, this right lets minority shareholders “tag along” and sell their shares on the exact same terms.
Right of First Refusal (ROFR)
A right that gives existing shareholders or the company the option to buy shares before the owner can sell them to an outside stranger.
Co-Sale Right
Similar to tag-along rights, it lets an investor sell a portion of their shares alongside a founder if the founder is selling some of their personal shares.
Board Seat
A formal position on the company’s board of directors. This gives an investor real governance power and a say in major decisions. Investors often negotiate for a board seat.
Protective Provisions
A set of veto rights given to preferred stockholders. For any major company change (like a sale, a new funding round, or a change to the business), the company must get the preferred investors’ sign-off first.
Vesting Acceleration
A clause that speeds up the vesting of an employee’s equity. Single-trigger acceleration vests some shares instantly if the company is bought. Double-trigger requires two things: the company gets bought, and the employee gets fired, which is much more common and fairer.
No-Shop Clause
A binding promise in a term sheet where the startup agrees not to solicit offers from other investors or buyers for a set period (like 30-60 days) while the current deal is finalized.
Option Pool Shuffle
A negotiation tactic. Investors often require founders to expand the employee option pool before an investment closes. This way, the dilution from creating the new pool lands entirely on the founders, not the new investor.
MFN Clause (Most Favored Nation)
A clause that says if a startup issues a new SAFE or note with better terms in the future, this investor can choose to take those new, better terms instead. It ensures they get the best deal.
5. Metrics & Unit Economics
KPI (Key Performance Indicator)
A key number you track to measure progress toward a specific goal. It is your scoreboard.
North Star Metric
The single most important metric that best captures the core value your product delivers to users. The whole company aligns around making this one number go up.
CAC (Customer Acquisition Cost)
How much it costs, on average, to win one new customer. CAC = Total sales & marketing spend / New customers acquired.
LTV / CLV (Customer Lifetime Value)
The total revenue you expect to earn from a single customer over the entire time they do business with you.
LTV: CAC Ratio
The classic health check for your business model. It compares the value of a customer to the cost of getting them. A ratio of 3:1 is often considered healthy. Below 1:1 means you are losing money on every new customer.
CAC Payback Period
How many months it takes for a customer to generate enough profit to pay back their own acquisition cost. A shorter payback period is better, as it means you recoup your investment faster.
Churn Rate
The percentage of customers (or revenue) you lose over a specific period. Churn = Customers lost / Customers at start of period. It’s the leaky bucket in your business.
Retention Rate
The flip side of churn. The percentage of customers you keep over a period. Retention = 1 – Churn Rate.
MRR (Monthly Recurring Revenue)
Predictable, subscription-based revenue you can count on every month. It is the heartbeat of a SaaS business.
ARR (Annual Recurring Revenue)
Yearly predictable revenue from subscriptions. ARR = MRR x 12.
ARPU (Average Revenue Per User)
Total revenue divided by the total number of users. It is a gauge of how well you are monetizing each user on average.
Gross Margin
The percentage of revenue left after you pay for the direct costs of delivering your product. Gross margin = (Revenue – COGS) / Revenue. It shows the basic profitability of what you sell.
Contribution Margin
Revenue from a unit minus all variable costs associated with that unit. It shows what each sale contributes toward covering your fixed costs and profit.
Unit Economics
The revenue and costs tied to a single unit, usually one customer. It is the acid test. If your unit economics don’t work at a small scale, they will never work at a large scale.
Cohort Analysis
Grouping users by a shared characteristic (often the month they signed up) to track their behavior over time. You are not looking at one big average, but at how a group from January behaves differently from a group from February.
Conversion Rate
The percentage of people who take a desired action out of the total who could have. For example, the percentage of website visitors who sign up, or free trial users who become paying customers.
Bounce Rate
The percentage of visitors who land on a page on your website and leave without doing anything else or viewing any other page.
DAU / MAU (Daily / Monthly Active Users)
A count of unique users engaging with your product each day or month. The DAU/MAU ratio (stickiness) tells you how often your monthly users return. A 50% ratio means the average user is coming back 15 days out of the month.
Net Revenue Retention (NRR)
A powerful metric that measures total revenue retained from your existing customer base over a year. It includes upgrades (expansion revenue), downgrades, and churn. An NRR above 100% means your existing customers are a source of growth on their own.
Gross Revenue Retention (GRR)
Measures revenue retained from customers, but only accounts for downgrades and churn. It purposely ignores expansion revenue from upgrades, so it can never be more than 100%. It is the purest measure of how sticky your product is.
Rule of 40
A popular SaaS health benchmark. Your revenue growth rate plus your profit margin should add up to 40% or more. It balances the trade-off between fast growth and profitability.
Magic Number
A sales-efficiency metric. It measures how much new recurring revenue you generate for every dollar you spend on sales and marketing. A higher number is better.
Burn Multiple
A framing for efficiency. It measures how much net cash you burn to add each dollar of new recurring revenue. A burn multiple of 1x is great; 2x is okay; 3x or higher means you are burning a lot of cash for the growth you’re getting.
TAM / SAM / SOM
Market sizing from biggest to smallest. Total Addressable Market (everyone, everywhere who could use your product). Serviceable Addressable Market (the slice of TAM you can actually reach with your business model). Serviceable Obtainable Market (the realistic, near-term share you can capture).
GMV (Gross Merchandise Value)
The total dollar value of goods sold through a marketplace over a period. This is the price of all the items, not the marketplace’s revenue from fees. It is a measure of the platform’s scale.
Run Rate
Taking your current performance and projecting it forward for a year. If you earned $1 million this month, your annual run rate is $12 million. It assumes nothing will change, which is never quite true.
6. Growth & Marketing
Growth Hacking
A creative, low-cost, and experiment-driven approach to rapidly accelerating user or revenue growth. It is less about big ad budgets and more about clever tactics.
Product-Led Growth (PLG)
A strategy where the product itself does the selling. Users sign up for a free trial or a freemium version, experience the value firsthand, and then upgrade to a paid plan on their own. The product drives acquisition.
Sales-Led Growth
A growth model driven primarily by a human sales team, common for complex, high-priced products sold to big companies.
Flywheel
A business model where each part of the business feeds the next, creating a self-reinforcing loop that compounds momentum over time. A happy customer attracts more users, which makes the product better, which makes customers happier, and so on.
Funnel
The step-by-step journey a user takes from first hearing about you to becoming a paying customer. It is widest at the top (awareness) and narrowest at the bottom (purchase).
Pirate Metrics (AARRR)
A classic five-step funnel framework. Acquisition (how users find you), Activation (their first good experience), Retention (how many come back), Referral (how they tell others), Revenue (how you make money).
Virality / Viral Coefficient (K-factor)
How many new users each existing user brings in. If one user, on average, brings in 1.2 new users (a K-factor > 1), you have self-sustaining, exponential growth.
Network Effects
When a product or service becomes more valuable the more people use it. A phone is useless if you’re the only one who has one, but it becomes essential when everyone does. This creates a powerful moat.
Freemium
A model offering a free basic tier forever to attract many users, with the goal of some upgrading to a paid plan for premium features.
Free Trial
Temporary, full access to a paid product for a short time, like 14 or 30 days. The goal is to get users hooked so they convert to paying when the trial ends.
CTA (Call to Action)
The prompt or button that tells a user what to do next. Think “Sign Up Free,” “Get Started,” or “Buy Now.”
SEO / SEM
Search Engine Optimization is the art of earning free, organic traffic from search engines by making your website the best result. Search Engine Marketing is buying that traffic with paid search ads.
Content Marketing
Attracting and keeping customers by creating and sharing valuable, helpful content (like blog posts, videos, and guides) instead of just advertising.
Inbound Marketing
A strategy that draws customers in. They find you through content, SEO, and social media. It is about being a magnet, not a billboard.
Outbound Marketing
A strategy that pushes a message out to potential customers, like cold emails, cold calls, and banner ads. It is the billboard approach.
ICP (Ideal Customer Profile)
A detailed description of the exact type of company that gets the most value from your product. This is for B2B sales and targets the company, not the person.
Buyer Persona
A semi-fictional profile of your perfect individual customer, based on research and data. It describes their goals, pains, and behaviors.
Lead / MQL / SQL
A lead is any potential customer. A Marketing Qualified Lead (MQL) has shown interest (like downloading a guide) but isn’t ready to buy. A Sales Qualified Lead (SQL) has a clear intent to buy and is ready for a sales call.
Waitlist
A sign-up list of interested users you collect before launching. It is a great way to build hype and measure demand.
Referral Loop
A built-in feature in your product that encourages users to invite others, like Dropbox’s “get free space for inviting a friend” prompt. It turns customers into your growth engine.
Churn Reason Analysis
The process of systematically tagging and analyzing why customers cancel. It is the post-mortem data you need to stop the bleeding.
NPS (Net Promoter Score)
A simple survey that asks customers, “On a scale of 0 to 10, how likely are you to recommend us to a friend?” It is a benchmark for customer loyalty and sentiment.
7. Product & Engineering
Wireframe
A basic, low-fidelity blueprint of a screen. It is like an architectural floor plan for an app, showing the layout and structure without any visual design or color.
Prototype
An early interactive model of a product used to test ideas and flows before committing to a full build. It is for learning, not shipping.
Roadmap
The high-level plan of what you will build and when. It communicates priorities and the strategic direction of the product over time.
Sprint
A short, fixed work cycle (often two weeks) in which a team completes a set of planned tasks. It’s a time-boxed race to a goal.
Agile
A philosophy for building software that emphasizes iterative development, cross-team collaboration, and adapting to change quickly.
Scrum
A specific, structured framework for implementing Agile. It uses sprints, a daily standup meeting, and defined roles (like Scrum Master and Product Owner).
Backlog
The master, prioritized list of all the features, bug fixes, and tasks the team needs to work on. It is the product’s to-do list.
Feature Creep
The dangerous tendency to keep adding more and more features, making the product bloated, complicated, and losing its core focus.
Technical Debt
The hidden cost of taking a quick-and-dirty engineering shortcut now instead of building it cleanly. Like financial debt, you have to pay it back with “interest” later by fixing the messy code.
UX (User Experience)
How a product feels to use. It focuses on the overall flow, ease of use, and whether the product solves a problem in an intuitive way.
UI (User Interface)
How the product looks. It focuses on the visual elements: the buttons, typography, colors, and layout that users interact with.
A/B Testing
A live experiment where you show two versions of something (like a button or a headline) to different users to see which one performs better. Version A is the control, Version B is the challenger.
Alpha / Beta
Early testing stages. Alpha is a rough version, usually internal, to find major bugs. Beta is a more polished version released to a limited group of external users for real-world feedback.
Iteration
The process of repeatedly refining a product. You build, get feedback, learn, and make small changes in a continuous loop.
Ship / Shipping
The act of releasing a new feature or product to real users. “Ship fast” is a mantra that means it’s better to learn from a live product than to polish a perfect one in a dark room.
Dogfooding
Short for “eating your own dog food.” It means using your own product internally every day to find bugs and truly understand the user’s pain.
API (Application Programming Interface)
A defined way for two different software systems to talk to each other and share data or functionality. It is the plumbing that connects apps.
SaaS / PaaS / IaaS
Cloud service models. Software as a Service (ready-to-use software like Gmail). Platform as a Service (a platform to build your own apps on). Infrastructure as a Service (on-demand computing hardware like servers and storage).
No-Code / Low-Code
Tools that let people build software and websites using visual drag-and-drop instead of traditional coding. It makes building digital products much more accessible.
Tech Stack
The combination of programming languages, frameworks, databases, and tools a company uses to build and run its product.
Microservices
An architecture where a single application is built as a collection of small, independent services. Each service runs its own process and can be updated without rebuilding the entire app.
Monolith
The opposite of microservices. An application built as a single, large, unified unit. It’s often the faster way to start, but can become hard to manage as the codebase grows.
8. Finance & Accounting
Revenue
The total money coming into a business from its sales before any costs are deducted. The “top line.”
Profit
What’s left of revenue after you pay all costs and expenses. The “bottom line.” Profit is not the same as cash.
Gross vs Net
Gross is the total before deductions. Net is what’s left after all deductions. So, Gross Revenue minus costs equals Net Income.
COGS (Cost of Goods Sold)
The direct costs of making or delivering what you sell. For a software company, this is mostly hosting costs. For a coffee shop, it’s the beans, cup, and milk.
OpEx (Operating Expenditure)
The ongoing day-to-day costs of running a business. Think salaries, rent, marketing spend, and software subscriptions.
CapEx (Capital Expenditure)
Large, one-time investments in long-term assets like buildings or heavy machinery. In software startups, this is rarely a big deal.
P&L (Profit & Loss Statement)
A financial report that summarizes your revenues, costs, and expenses over a period of time, like a quarter or a year. It shows if you are profitable.
Balance Sheet
A financial snapshot of a moment in time. It shows what a company owns (assets), what it owes (liabilities), and the net worth of the business (equity). The formula is Assets = Liabilities + Equity.
Cash Flow
The actual movement of money in and out of the business. Positive cash flow means more cash is coming in than going out. A company can be profitable on paper but still die from negative cash flow.
EBITDA
Earnings Before Interest, Taxes, Depreciation, and Amortization. It’s a measure of the core operating profitability of a business, stripping out factors that depend on accounting and financial decisions.
Break-Even Point
The sweet spot where your total revenue equals your total costs. You are not losing money, but you are not making a profit yet either. You are surviving on your own.
Working Capital
The money available to run daily operations. Working Capital = Current Assets – Current Liabilities. It is the short-term cash you need to pay bills and employees.
Accounts Receivable (AR)
Money your customers legally owe you for a service you have already delivered but haven’t been paid for yet. It’s an IOU from a customer.
Accounts Payable (AP)
Money you owe to your suppliers. It’s an IOU you’ve given to someone else.
Bridge Financing
A short-term loan to cover a temporary cash crunch until a larger round of funding or a big payment arrives.
R&D (Research and Development)
Spending on creating new products or improving existing ones. For a tech startup, this is often the salary of the engineering team.
All-Hands
A regular company-wide meeting where the leadership team shares major updates, metrics, and strategy with every single employee.
9. Operations, Team & Culture
Co-Founder Agreement
A legal document among founders that spells out equity splits, roles, responsibilities, and what happens if a founder leaves. It is a pre-nup for your business relationship.
OKRs (Objectives and Key Results)
A popular goal-setting framework. An Objective is a qualitative, ambitious goal. Key Results are the specific, measurable numbers that tell you if you achieved the objective.
KPI (Key Performance Indicator)
A metric chosen to track progress. OKRs are the goals, KPIs are the ongoing health checks. (Yes, it appears in metrics too, but it’s a core operational tool.)
Standup
A short, daily team meeting, often done standing up to keep it brief. Each person says what they did yesterday, what they’re doing today, and if there are any blockers.
Async (Asynchronous Communication)
A way of working where you don’t need an immediate reply. Think of a well-written document or a recorded video instead of a meeting. It is the heart of effective remote work.
Remote-First
A company culture designed so that remote employees are the default, not an afterthought. All processes, from meetings to social events, are built for online collaboration.
Hybrid Work
A work model where employees split their time between an office and a remote location, like working from home on Mondays and Fridays.

Advisory Board
An informal group with no legal power. They give advice and connections but cannot vote on formal decisions.
Culture Fit
Hiring someone who aligns with your existing company values and behaviors. It keeps the culture strong.
Culture Add
A better way to think about hiring. Instead of just “fitting in,” what new perspective or background does this person bring that will enrich the company culture?
Ramen Profitable
A cheeky term for earning just enough money to cover the founders’ basic living expenses, like rent and instant ramen. It’s survival-level profitability that gives you freedom.
Burnout
Physical and emotional exhaustion caused by prolonged stress and overwork. It is a real and serious risk in high-pressure startup environments.
Psychological Safety
A shared belief by a team that it’s safe to take risks, ask questions, and admit mistakes without being punished or humiliated. Google’s research found it’s the top indicator of a high-performing team.

A cultural value that prioritizes moving quickly, making a decision, and learning from doing, rather than spending forever in analysis paralysis.
10. Exits & Later Stage
Exit
The big event where founders and investors turn their paper ownership (equity) into real cash. This usually happens through an acquisition or an IPO.
Exit Strategy
The long-term plan for how investors will make a return. It’s not a detailed map, but more of a stated ambition like a future IPO or strategic sale.
Acquisition
The most common exit. Another company buys your startup, either for your technology, your team, or your market share.
Acqui-hire
A type of acquisition where the main prize is the talented team, not the product they built. The buyer is hiring an entire team in one shot by buying their company.
Merger (M&A)
When two companies combine to form a new single entity. “M&A” is the umbrella term for all mergers and acquisitions.
IPO (Initial Public Offering)
The first sale of a company’s shares to the public on a stock exchange. You go from a private company to a public one.
Direct Listing
A way to go public by listing existing shares directly, without issuing new shares or raising new money. It skips the traditional IPO roadshow.
SPAC (Special Purpose Acquisition Company)
A shell company that raises public money and goes public for the sole purpose of merging with a private company. It is a shortcut to taking a company public.
Secondary Sale
When an existing shareholder (like a founder or early investor) sells their private shares directly to another buyer, rather than the company issuing new shares. The founder gets personal liquidity.
Tender Offer
A structured, company-blessed event where multiple shareholders are invited to sell a portion of their shares to a buyer (often an investor) at a set price.
Liquidity Event
Any event that turns an asset, like a startup share, into spendable cash. An IPO, an acquisition, and a secondary sale are all liquidity events.
Earn-out
Part of an acquisition deal. A portion of the purchase price is not paid upfront. It is held back and paid out over time only if the acquired company hits specific financial or product goals.
Lock-up Period
A window, usually 90 to 180 days after an IPO, during which existing insiders (founders, employees) are contractually forbidden from selling their shares.
Wind Down / Winding Up
The process of formally ending a company’s existence. You pay off what debts you can, shut down operations, and dissolve the legal entity.
Insolvency / Bankruptcy
Insolvency is the state of being unable to pay your debts when they are due. Bankruptcy is the legal process that follows, where a court steps in to sort out the mess.
Fire Sale
Selling a company or its assets very quickly at a steep discount, usually out of sheer desperation to get some money back before shutting down.
Zombie Startup
A company that is neither dead nor thriving. It has stalled, has no meaningful growth, and no clear path to an exit. It just kind of exists.
Write-Off
An investor’s admission that an investment is worth zero. They “write it off” on their books to take the loss and move on.
Goodwill
An intangible asset on a balance sheet that represents the extra amount a buyer paid for a company above its hard assets. It captures the value of the brand, customer base, and reputation.
11. Legal & Structure
Incorporation
The act of legally forming a company as a separate entity from its owners. It creates a wall between personal and business assets.
LLC (Limited Liability Company)
A simple, flexible US company structure that protects personal assets. Profits pass through to owners’ personal taxes. It is not ideal for VC funding.
C-Corp (C-Corporation)
The standard US structure for VC-funded startups. It is a separate legal entity that pays its own taxes and can easily issue stock. Most are set up in Delaware.
Pvt Ltd (Private Limited Company)
The standard company structure for startups in India. It is a separate legal entity, limits owner liability, and can accept outside investment.
Delaware Flip
A complex process where a non-US startup restructures so a new US (usually Delaware) C-Corp becomes the parent company. It is almost mandatory when raising from major US venture funds.
IP (Intellectual Property)
Creations of the mind that are legally protected. This includes patents (inventions), trademarks (brand names/logos), copyrights (creative works), and trade secrets (secret recipes).
NDA (Non-Disclosure Agreement)
A simple contract where someone promises to keep the information you share with them confidential. It is a legal pinky-swear.
Compliance
The boring but critical job of making sure a company is following all the laws and regulations that apply to its business.
Regulatory Sandbox
A special, temporary safe space created by regulators where startups can test innovative products on real customers without immediately having to follow every single rule.
Data Privacy (GDPR, DPDP, CCPA)
Laws governing how you can collect, store, and use personal data. GDPR covers the EU, DPDP is India’s act, and CCPA is for California. Messing this up means huge fines.
IP Assignment Agreement
A legal must-have. Every founder and employee must sign this to confirm that anything they create for the company belongs to the company, not to them personally.
Par Value
The arbitrary nominal face value of a single share of stock. It has nothing to do with the actual value of the company. It is a legal detail, usually set to a tiny fraction of a cent.
12. India-Specific Terms
DPIIT Recognition
Official recognition from the Department for Promotion of Industry and Internal Trade. It gives an Indian startup a certificate that unlocks access to tax benefits, easier compliance, and government funding schemes.
Angel Tax
A controversial tax that was once levied on the premium a startup raised above what a tax officer deemed its “fair value.” It was a major pain point for Indian founders but has been largely relieved by recent reforms.
Startup India
A major government initiative designed to make life easier for startups. It provides tax holidays (like a three-year tax break), easier compliance, and a fund of funds to support the ecosystem.
GIFT City
Gujarat International Finance Tec-City. It is India’s new international financial services hub with special regulatory and tax advantages, increasingly used for structuring venture funds and fintech companies.
ONDC (Open Network for Digital Commerce)
A government-backed open protocol network aiming to break up the e-commerce monopoly. It lets any buyer app connect to any seller, just like how you can email a Gmail account from Yahoo.
Bharat / Tier 2-3 Focus
Shorthand for building products specifically for India’s non-metro, smaller-city users (“Bharat”). This is about serving the next half a billion internet users who speak different languages and have different needs than those in Delhi or Mumbai.
ESOP Buyback
An event where a startup uses its own cash to repurchase vested employee stock options. It is a powerful way to give employees real cash liquidity long before an IPO, and it’s becoming a common practice in India’s biggest startups.
RoC Filing (Registrar of Companies)
The mandatory annual and event-based reports that every Indian company must file with the Ministry of Corporate Affairs. This is the compliance paper trail. Miss a filing, and you get in trouble.
Debt Fund
A venture debt fund, a category of Alternative Investment Fund (AIF) in India, that provides loans to startups. It has become a major asset class as a complement to equity funding.
FDI (Foreign Direct Investment)
Investment from a foreign entity directly into an Indian company. There are automatic and government approval routes depending on the sector, and it’s a key source of capital.
13. Slang, Culture & Buzzwords
Lean Startup
A methodology from Eric Ries that is like the scientific method for business. You build a tiny experiment (MVP), measure the results, and learn whether to pivot or persevere. The goal is to avoid building something nobody wants.
Blitzscaling
A strategy from Reid Hoffman that puts speed over efficiency. The goal is to become huge at a breakneck pace to dominate a market before competitors even know what hit them, even if it’s massively risky.
Moonshot
An insanely ambitious, groundbreaking project that aims for a 10x improvement, not a 10% one. Think of it as trying to literally shoot for the moon.
Hockey Stick Growth
The dream growth chart. It is a curve that is flat for a while and then suddenly bends sharply upward, looking like a hockey stick. It represents the inflection point of explosive growth.
Vanity Metrics
Numbers that look impressive on a slide but don’t actually tie to business health or revenue, like total downloads, page views, or followers. They make you feel good but don’t help you make decisions.
Actionable Metrics
The opposite of vanity metrics. These are numbers that show clear cause and effect and help you make better decisions. For example, the conversion rate from a specific A/B test.
Founder-Market Fit
When a founder has a unique, almost unfair background, insight, or passion that makes them the perfect person in the world to solve their specific problem. It’s a signal of a deep, personal connection to the mission.
Vaporware
A product that is announced and hyped with a big launch, but never actually shipped to customers. It’s all vapor, no substance.
Smoke Test
A low-cost way to gauge customer demand for a product before you build it. A classic example is a landing page with a “Sign Up” button that just says “coming soon” to see how many people click.
Concierge MVP
A way to validate a business by manually performing the service yourself for your first few customers. It looks automated to them, but behind the scenes, it is you doing the work by hand.
Wizard of Oz MVP
Similar to a concierge MVP, but the illusion is deeper. The customer thinks they are using a real automated product, but behind the curtain, a person (the Wizard) is pulling levers and running things manually.
Cockroach
A scrappy startup celebrated not for flashy growth, but for its unkillable survival instinct. It can live through anything, just like a cockroach. It is the opposite of the fragile unicorn.
FOMO (Fear of Missing Out)
The powerful anxiety that someone else is getting a great deal or a hot investment that you are missing. This psychological driver is very real in startup investing.
Hustle Culture
The glamorization of working 24/7 and making your job your entire identity. While hard work is essential, this toxic version is now widely questioned for leading directly to burnout.
The Dip
A concept from Seth Godin. It’s the hard, dead-zone part of any project between starting and mastering it. Knowing if you are in a temporary Dip worth pushing through or a dead-end is a key startup survival skill.
Sunsetting
The polite business term for killing a product or shutting down a feature. The sun is setting on it for good.
Pivot to Video
A now-sarcastic term from the media world, referring to a desperate, poorly-thought-out pivot a company makes just because a new trend seems hot, like how many media companies “pivoted to video” and failed.
Stealth Mode
When a startup operates in total secrecy before launch to avoid tipping off competitors. They build in the shadows and then make a big splash.
Learning Curve
How quickly you can pick up a new skill or understand a complex product. A “steep learning curve” means it is hard to learn.
Deep Tech
Startups whose business model is built on substantial scientific or engineering breakthroughs, not just a clever business model. Think AI, biotech, or quantum computing. It is hard to copy and takes a long time to build.
