How it works

SAFEs are simple to sign but brutal to stack. Model your cap table before your Series A term sheet shows up.

Step 1

Plug in your SAFEs

Enter every SAFE you signed — pre-money, post-money, MFN, capped, uncapped. We handle the conversion math.

Step 2

Model the round

Set your Series A price and see exactly how each SAFE converts, what the option pool costs, and where founders land.

Step 3

See the damage

Compare what you thought you owned vs. what you actually own. Share it with your co-founder. Misery loves company.

The math is dead serious. The rest is just coping.

Full SAFE conversion logic, option pool shuffles, and pro-rata — in 30 seconds.
