Founder calculators
Founder calculators answer the quick equity questions you have between board meetings — without a spreadsheet. They run off your live cap table, so the numbers are real.
Open Calculators from the cap-table header. Everything here is a quick estimate off your current fully-diluted total (including options and the unallocated pool), using the same pre-money-shuffle math as the pro-forma scenario.
Can I grant X% to someone?
Enter a target ownership percentage and the calculator tells you how many options or shares to grant so the person lands at that percentage of the post-grant fully-diluted cap table — plus whether your option pool has enough unallocated room to cover it.
How much option pool do I need?
Enter a target pool size as a percentage of fully-diluted, and the calculator tells you how many shares to add to reach it (or confirms your current reserve is already enough). Investors often want a specific pool top-up as a condition of a round — this sizes it.
What if I raise?
Modeling new money, SAFE conversions, and the resulting dilution is what the scenario and priced-round tools are for — start there, then record the round for real when it closes.
