Own equity, and know what it is worth.

You will not get rich renting out your time. You get there by owning a piece of the business, and by reading what it is worth at every round. The Lab is a set of small, single purpose instruments that run the real math on your own company and tell you something true. What you keep after this round. How many months of cash you have left. Whether your split is fair.

Built for pre-seed, pre-revenue founders, anywhere. The same finance work I do for clients, minus the invoice.

Privacy by default. The math runs in your browser. Nothing leaves this page unless you ask for the readout by email. You can run every number without typing your name.

The bench

Leverage is a number you can read, and the fundamentals are specific knowledge you can build. Run the instruments, then test yourself, all free and all in your browser.

Dilution Scan

Cash, burn and your zero cash date, plus how much to raise for 18 to 24 months to your next milestone, and the dilution that raise costs you.

Your cash lasts about 10 months.

Split Test

In the lab

Contribution, role and risk go in. A fair cofounder split and a vesting schedule come out, with the 83(b) or Swiss equivalent reminder built in.

A fair split is 55 / 45, vesting over four years.
Week 3

Model Lab

In the lab

A pre-revenue model you can actually defend. A handful of drivers go in, a clean three statement view and a runway curve come out.

A model a VC will not poke holes in.
