Cap Table and Dilution Explained for First-Time Founders
Unicorn Rivals Team
Valuation Is Vanity; Cap Table Is Sanity
TechCrunch writes about your valuation. Your lawyer cares about your cap table — who owns what percentage today, and who will after the next round.
First-time founders confuse:
- Dilution (ownership shrinking)
- Valuation (price tag on the company)
- Proceeds (what you actually take home at exit)
This post untangles all three — before you sign your first SAFE or term sheet. Pair with pre-seed vs seed and bootstrap vs VC.
What a Cap Table Actually Is
A cap table is a spreadsheet (or Carta export) listing:
| Stakeholder | Shares / % | Notes |
|---|---|---|
| Founders | 70–90% early | Often splits 50/50 or weighted |
| Option pool | 10–15% | Future employees |
| Investors | Grows each round | Angels, seed, Series A… |
| Advisors | 0.25–1% each | Vesting common |
Update it before every raise — not after lawyers send the closing docs.
How Dilution Works (Multiplicative, Not Additive)
Giving away "10%" doesn't always mean you lose exactly 10 points on a 100-point scale if you already diluted.
Round 1: 10% to angel → founders keep 90%
Round 2: 15% to seed → founders keep 90% × 85% = 76.5%
Round 3: 18% to Series A → founders keep 76.5% × 82% = 62.7%
Three rounds and you're near two-thirds — before option pool refreshes and secondary sales.
We model the same math in-game — see equity dilution and exit impact.
Option Pool: Hidden Dilution
Investors often ask for a 10–15% option pool pre-money — meaning founders absorb that dilution before new money arrives.
| Without pool refresh | With 15% pool pre-money |
|---|---|
| Founders 80% | Founders ~68% before check |
| Cleaner cap table | Easier to hire, harsher on founders |
Negotiate pool size and timing. "Standard" isn't always fair for your stage.
Exit Proceeds: The Number That Pays Your Mortgage
At acquisition or IPO, payout = your % × exit value − preferences.
Investors with liquidation preferences (1×, participating, etc.) get paid first. Founders celebrating a $100M exit with heavy preferred stacks sometimes walk away with less than expected.
Read startup exit options for paths — and understand liquidation preferences before you agree to terms you don't recognize.
Cap Table Hygiene Checklist
| Habit | Why |
|---|---|
| Model pro forma before signing | No surprise "where did my % go?" |
| Track vesting cliffs | Departing co-founder equity returns to pool |
| Document advisor grants | Handshake equity kills companies |
| Align with co-founder split early | Emotion + equity = conflict |
| Revisit at each investment round | Story and math stay honest |
Common First-Timer Mistakes
| Mistake | Consequence |
|---|---|
| 50/50 split with no vesting | One founder leaves, company stuck |
| Raising because "everyone does" | Unnecessary dilution |
| Ignoring dilution at small checks | Death by a thousand SAFEs |
| Optimizing valuation over terms | Preferences eat exit |
| No lawyer on first institutional round | Expensive fixes later |
