That’s why a quick cheat sheet of the most common jargon is worth its weight in equity. ## Why a Cheat Sheet Helps When I was building my first company, I spent more evenings Googling buzzwords than actually building the product. It felt like learning a new language while trying to run a marathon. A clear, plain‑English list lets you focus on the work that matters—building, selling, and learning—without getting stuck on the dictionary. If you need an even quicker reference before a pitch, the [12‑word cheat sheet](/startupglossary/startup-term-cheat-sheet-12-essential-words-every-founder-needs-before-their-first-pitch) is a handy starter. ## How to Use This List Treat this as a reference you can skim before a meeting, or keep it open in a browser tab while you draft an investor email. The definitions are short on fluff and long on clarity. If a term feels fuzzy, read the example right after it; that’s usually where the meaning clicks. ## The 40 Terms Every Founder Should Know ### Funding & Finance **1. Angel Investor** – A wealthy individual who puts personal money into early‑stage startups, often in exchange for equity and mentorship. **2. Series A/B/C** – Successive rounds of venture capital financing. Series A is the first big round after seed; B and C follow as the company grows. For a concise rundown of the most critical financing vocabulary, see our [top‑ten funding terms guide](/startupglossary/entrepreneur-s-glossary-guide-decoding-the-top-10-funding-terms-for-early-stage-startups). **3. Pre‑money Valuation** – The value of the company before new money comes in. It sets the price per share for the round. **4. Post‑money Valuation** – The company’s value after the new cash is added. It equals pre‑money valuation plus the amount raised. **5. Burn Rate** – How fast you spend cash each month. A high burn rate means you need more funding sooner. **6. Run‑rate** – Annualized version of your current monthly revenue or burn. Multiply the month’s number by 12 to get a quick picture. Pairing run‑rate with runway calculations gives a fuller picture of your cash [runway](/startupglossary/decoding-runway-and-other-funding-metrics-a-clear-guide-for-firsttime-entrepreneurs). **7. Cap Table** – A spreadsheet that shows who owns what percentage of the company. It’s the ownership map. **8. Dilution** – The reduction in each owner’s percentage when new shares are issued. It’s normal but worth tracking. **9. Convertible Note** – A short‑term loan that converts into equity during a later financing round, usually at a discount. **10. SAFE (Simple Agreement for Future Equity)** – Like a convertible note but without interest or a set maturity date. ### Product & Development **11. MVP (Minimum Viable Product)** – The simplest version of your product that still solves the core problem. It’s built to test assumptions fast. **12. PMF (Product‑Market Fit)** – The sweet spot where customers love your product enough to pay for it and tell others. **13. Pivot** – A strategic change in direction based on what you’ve learned from users or the market. **14. KPI (Key Performance Indicator)** – A metric that tells you how well you’re doing on a specific goal, like churn or CAC. **15. Cohort Analysis** – Grouping users by the time they started using your product to see how behavior changes over time. **16. Churn Rate** – The percentage of customers who stop using your product in a given period. Lower churn means healthier growth. **17. LTV (Lifetime Value)** – The total revenue you expect to earn from a customer over the whole time they stay with you. ### Growth & Marketing **18. CAC (Customer Acquisition Cost)** – How much you spend to win a new paying customer, including ads, sales salaries, and tools. **19. CAC:LTV Ratio** – A quick health check. Ideally, LTV should be at least three times CAC. **20. Funnel** – The series of steps a prospect goes through from awareness to paying customer. **21. SEO (Search Engine Optimization)** – Tactics to make your site rank higher in Google without paying for ads. **22. SEM (Search Engine Marketing)** – Paid search ads, like Google Ads, that drive traffic instantly. **23. Content Marketing** – Creating useful articles, videos, or podcasts to attract and keep an audience. **24. Growth Hacking** – Low‑cost, creative experiments to grow the user base quickly. Think of it as marketing on a startup budget. **25. Virality Coefficient** – The average number of new users each existing user brings in. A coefficient above 1 means exponential growth. ### Operations & Legal **26. Incorporation** – The legal process of forming a company, usually as a C‑corp in the US for VC‑friendly equity. **27. Bylaws** – Rules that govern how a corporation runs, covering things like board meetings and voting rights. **28. Vesting** – The schedule by which founders or employees earn their equity over time, often four years with a one‑year cliff. **29. Cliff** – The first period (usually one year) before any equity vests. It protects the company if someone leaves early. **30. Term Sheet** – A non‑binding outline of the key terms a VC will offer. It’s the roadmap before the legal contract. **31. Due Diligence** – The deep dive investors do to verify your numbers, legal standing, and market claims. ### Metrics & Analytics **32. ARR (Annual Recurring Revenue)** – The predictable revenue you expect each year from subscription customers. **33. MRR (Monthly Recurring Revenue)** – Same as ARR but measured monthly. It’s the heartbeat of SaaS businesses. **34. Gross Margin** – Revenue minus the cost of goods sold, expressed as a percentage. Higher margin means more money left for growth. **35. Net Promoter Score (NPS)** – A simple survey asking customers how likely they are to recommend you. Scores above 50 are considered great. **36. DAU/MAU Ratio** – Daily active users divided by monthly active users. It shows how sticky your product is. ### People & Culture **37. Founders’ Agreement** – A contract that spells out roles, equity splits, and what happens if someone leaves. **38. Advisory Board** – A group of experienced mentors who give advice but usually don’t have equity or voting rights. **39. OKR (Objectives and Key Results)** – A goal‑setting framework that links big objectives to measurable results. **40. Culture Fit vs. Culture Add** – Instead of hiring only people who “fit” the existing vibe, look for those who add new strengths and perspectives. ## Quick Tips for Remembering the List 1. **Group by Theme** – When you hear “burn rate,” you’ll instantly think “finance.” Keep the categories in mind. 2. **Use Flashcards** – A few minutes a day with a phone app can cement the terms. 3. **Teach Someone Else** – Explaining a term to a friend forces you to clarify it in your own mind. I’ve kept this cheat sheet short enough to read in a coffee break, but thorough enough to survive a boardroom Q&A. Keep it handy, refer back often, and you’ll spend less time Googling and more time building the next big thing.
