Try a scenario
No company yet, or just curious? Play out founders, an option pool, a SAFE, the usual rounds and an exit. One table per step, with the math behind every number. Nothing is saved.
1. Open it
- With no company: on the Welcome screen, click Try a scenario.
- With a company open: on the cap table, click Try a scenario. The first chip, Today, is your cap table as it is; you can add a priced round or an exit on top of it (to add a SAFE or a pool for real, use + New on the cap table).
2. Add steps
- Founders: names and shares. The first table appears as soon as both are filled in.
- + Add step: an Option pool (by percent of fully diluted, or by shares), a SAFE (amount, post-money cap, optional discount), a Priced round (the percent it sells, or new money and a pre-money valuation, with an optional pool top-up), or an Exit (what the company sells for).
- Use the typical rounds fills in a normal run: seed, Series A and Series B at the medians Carta reports, with the source and year shown under the button. Change or remove any of them.
- Click a chip on the right to see that step's table. Change is the move in percentage points from the step before; an exit shows each holder's proceeds instead. How is this calculated? under a holder shows the formula with the real numbers.
A SAFE converts at the next priced round on the YC post-money method: the investor's share of the company before the round is exactly amount ÷ cap. Unissued options are cancelled at an exit, so the pool gets nothing. Exit numbers are before liquidation preferences and exercise prices, which can change them a lot.
3. Keep the real part
With no company open, Save as my cap table takes the founders, the pool and the SAFEs into Create company and the setup, filled in for you. Rounds that haven't happened are never saved; the app records a priced round when it actually closes. Leaving the screen clears the steps.

Words used here
- Fully diluted
- Every share that exists or could exist: issued shares, granted options and the unissued pool. Percentages here are of that total.
- Post-money cap
- The valuation a SAFE converts at, counting the SAFE money itself. The investor's share before the next round is amount ÷ cap.
- Pool top-up
- Investors often ask for the option pool to be a set percent after the round, created before their money comes in, so it dilutes the founders, not them.
