Ventures

Where a founding team keeps its cap table

Form a venture with your co-founders, split the equity between you, and add each round as it happens. Everybody sees the same cap table, talks in the same place, and can send a working model into the conversation instead of a screenshot. The calculators stay open to everyone, signed in or not.

What an account is for

Settle the equity conversation early

Splitting equity with your friends is the conversation nobody wants to start, and the one that ends companies when it happens too late. Have it here, with everybody agreeing from their own account and a record of what was agreed, by whom and when.

Rooms with teams at your stage

Every round your venture raises opens a room with founders who have reached the same point, from other universities and other countries. You get a badge for the round too, with a page you can share it from.

Free, and open to anyone
