About

Model a full cap table in seconds: founders, SAFEs converting at the next priced round, an option pool top-up, and new investor ownership. Built to show the dilution mechanics that paper cap tables hide.

How it works

  1. 01Add founders and their starting share counts.
  2. 02Define your outstanding SAFE (amount + cap) and the planned option pool percentage.
  3. 03Enter the priced round amount and pre-money.
  4. 04We solve for post-money ownership across founders, SAFE holders, the new pool, and the new investor.

Examples

Two founders + $500k SAFE + Seed

Two founders at 6M / 4M shares, a $500k SAFE at $8M cap, a 10% pre-money pool, raising $3M at $12M pre. Founders end around 58%, SAFE holders ~4%, pool 10%, new investor 20%.

Heavy SAFE stack

Stacking multiple SAFEs at low caps can quietly take 15–25% before your priced round. Model each one to see the true dilution before signing the next note.

FAQ

Does this handle multiple SAFEs?+
Today it handles one aggregated SAFE position. For multiple SAFEs at different caps, sum the amounts and use a weighted-average cap as a rough estimate, or model them as a single 'SAFE pool'.
Pre-money vs post-money pool?+
We model a pre-money option pool — the dilution falls on founders before the new investor. Post-money pools shift dilution to investors, which is more founder-friendly but rarer in priced rounds.
Are MFN and discount terms supported?+
Not in this builder — use the dedicated SAFE → Equity Converter for cap vs. discount comparisons.
Can I export this to my real cap table?+
Not yet. Use the breakdown as a pre-term-sheet model; for issuance, switch to Carta, Pulley, or AngelList Equity.
