The Startup Glossary: Words You'll Keep Hearing (and What They Actually Mean)

If you've been reading this series — or talking to investors, lawyers, or other founders — you've probably hit a wall of terminology that no one stops to explain. Everyone just assumes you know what a liquidation preference is. They assume "pro-rata" makes sense to you. They drop "SAFE" into a sentence and move on.

This article is the one we'll link back to every time we use a term you might not be familiar with. Bookmark it. Come back to it. It'll make more sense every time you return.

These aren't definitions for their own sake. Every word here represents a real decision someone will ask you to make — about your money, your ownership, your company.

📄 Documents & Agreements

Term	What it means
SAFE	Simple Agreement for Future Equity. An investor gives you money now, and gets shares later when a real valuation is set. No valuation negotiation upfront — that's the point.
Convertible Note	Similar to a SAFE, but it's technically a loan that converts into equity later. It has an interest rate and a maturity date. SAFEs are simpler; notes are older.
Term Sheet	A non-binding document that outlines the key terms of an investment before the real legal documents are drafted. The number everyone obsesses over is valuation — but the other clauses matter just as much.
Cap Table	Short for capitalization table. A spreadsheet that shows who owns what percentage of your company — founders, investors, employees, everyone.
SHA	Shareholders' Agreement. The document that governs the relationship between everyone who owns shares in your company.

💰 Money & Valuation

Term	What it means
Valuation	What someone decides your company is worth. At early stages, this is as much art as it is math.
Pre-money valuation	What your company is worth before the investor's money goes in.
Post-money valuation	What your company is worth after the investment. Pre-money + the check = post-money.
Valuation Cap	The maximum value at which a SAFE or note converts into shares. It protects early investors — if your company grows a lot before the next round, they still get shares at the capped price, not the higher one.
Discount Rate	A percentage reduction on the share price at conversion, rewarding early investors for taking on early risk. If the discount is 20% and shares are priced at $1, they get them for $0.80.
Dilution	When new shares are issued, existing shareholders own a smaller percentage. Every funding round dilutes you. That's normal — as long as the value of what you own keeps growing.
Pro-rata rights	The right of an existing investor to participate in future funding rounds to maintain their ownership percentage. Keeps them from getting diluted out.

🏛️ Ownership & Equity

Term	What it means
Equity	Ownership in a company, represented as shares or a percentage.
Vesting	Your equity isn't fully yours on day one — you earn it gradually over time, usually four years. Protects everyone from a co-founder walking away early with a large stake.
Cliff	The point — usually 12 months — before which no equity vests at all. If you leave before the cliff, you get nothing. After the cliff, you've earned your first chunk.
Option Pool	A block of shares reserved for future employees. Usually created before a seed or Series A round. Investors will often ask you to set one up — and it comes out of your ownership, not theirs.
Common Stock	The type of shares founders and employees typically hold.
Preferred Stock	The type of shares investors typically hold. Comes with more rights and protections than common stock.
Liquidation Preference	A clause that determines who gets paid first — and how much — if the company is sold or shut down. Investors with preferred stock usually get their money back before founders see anything.

🏢 Structure & Governance

Term	What it means
Board of Directors	The governing body of a company. At early stages it's just founders. As investors come in, they often get a board seat — which means real influence over major decisions.
Board Seat	A position on the board. Whoever sits on the board votes on things like firing the CEO, approving big financial decisions, and future fundraising.
Anti-dilution provision	A protection for investors that adjusts their ownership if you later raise money at a lower valuation than the round they invested in.
Non-dilutive funding	Money that doesn't require giving up equity — grants, prizes, fellowships, competitions. The best kind of early capital.
Angel Investor	An individual who invests their own money in early-stage startups. Usually writes smaller checks than VCs, moves faster, and bets more on the person than the product.
VC / Venture Capital	A firm that pools money from institutional investors (universities, pension funds, etc.) and deploys it into high-growth startups in exchange for equity.
Accelerator	A program that gives startups a small investment, mentorship, and resources in exchange for equity — and usually ends with a demo day. Y Combinator is the most well-known.
Lead Investor	The investor who sets the terms of a round and usually writes the largest check. Others follow their lead.
