See how each funding round changes what you own. Model a pre-seed, seed and later rounds, with option pool top-ups, and compare your stake with the value it represents.

How to read the result

Price per share is the amount raised divided by the shares the new investors receive.
Founders shows your fully diluted ownership after the round, including the option pool.
Investors who put in money at an earlier round are shown separately so you can see how they are diluted too.
