Capper · Cap table mathematics
Cap-table math you can defend.
Capper runs SAFE math, dilution scenarios, and option-pool sizing. Shows the work — so you walk into the term-sheet meeting with answers.
Start free100 free tokens. No card. Drafts only — your accountant signs off.
Spreadsheet math at 2am.
Term sheet says $4M on $20M post. There's a 20% pool refresh. You're three SAFEs deep already. You don't know what your dilution looks like at close — and the call is at 9am.
- Cap-table tools price by stakeholder count, not by founder need.
- ChatGPT does the math wrong without telling you.
- Your spreadsheet from last round doesn't include the pool refresh.
Here’s what changes.
Capper
Run the post-close cap table in 30 seconds.
Capper takes today's cap table and the proposed terms. Runs the dilution. Shows the math step by step — so when an investor asks 'what's our share post-pool-refresh', you have the answer with the calculation. Securities-law adjacent, so every output carries the disclaimer.
- Models SAFEs, priced rounds, conversion at any cap.
- Sizes option pools to hit a post-money target.
- Compares two term sheets on dilution side by side.
- Disclaimer on every output — confirm with counsel and accountant.
