How long does your cash last, and what should you raise?

Enter your cash and your monthly burn. The scan reads your runway, the date the cash hits zero, and the one prescription that follows: how much to raise to buy 18 to 24 months to your milestone.

Your cash and burnEdit anything
Cash and burn

Bank balance plus any onchain treasury, counted in USD.

Cash out minus cash in, per month. Spend 60k, bring in 20k, that is 40k.

Your employee option pool. We flag it against the seed norm and note what it costs you in dilution.

RevenueDefault pre-revenue

Most of our founders are pre-revenue. Flip this only if money is coming in.

The milestone raise

Investors now expect a seed to buy 24 to 30 months. We default to 24, slide it to your plan.

Most teams step spend up after a raise. The default doubles today's burn. Set it to your real plan.

A rough valuation, only to price the dilution. The exact split lives in the Dilution Scan.

Leave at 0 for flat. Set it if your spend climbs as you hire, the runway above will shorten to match.

Runway to your target

This assumes a flat burn unless you set a growth rate, and that you raise from roughly today's cash position. With revenue on, it projects your spend and your revenue forward month by month, so growth can stretch the runway and reach breakeven. The burn multiple uses the David Sacks bands and only shows with growing revenue. The dilution cost is an estimate at one post-money; the exact split with your SAFEs is in the Dilution Scan. The time-to-PMF windows are rough medians from founder interviews (Lenny Rachitsky's B2B set, extended to other categories as directional guides), not a promise. None of this is advice.
