About

Most founders underestimate how quickly dilution adds up across funding rounds. Running an investor database app, we often get this question: “How much will I actually own after pre-seed and seed?” So we built a simple cap table calculator that lets you plug in your valuation, option pool, and investment amount and see how ownership changes in minutes. No spreadsheets. No overcomplicated finance terms. Just a clear way to understand dilution before you raise your round.
