Longevity for your organization.

Free finance tools for founders, and they run right in your browser. Model your dilution, runway and raise in minutes, nothing to install.

Net contents: one finance brain, part timeOne capsule a month.
Founders Lab: read your own numbers

You will not get rich renting out your time. You get there by owning equity, and by knowing what it is worth at every round. Run the real math on your own company, then test what you know, all in your browser, for free.

Dilution Scan

Stack your SAFEs with their cap and discount, the option pool and the priced round. See what you own now and after Series A, with the full dilution waterfall.

You keep 61 percent after this round.

Runway Scan

Cash and burn go in. Out comes your runway, your zero cash date, whether you are default alive, and the raise that buys 24 months to your next milestone.

10 months of runway, and what to raise to reach 24.

Split Test

Rate each founder on contribution, role and risk. Out comes a fair split, an option plan for your first 20 hires, and the vesting plus 83(b) or Swiss equivalent reminder.

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

Fundability Scorecard

Ten markers an investor actually reads, scored the way they score them. See your raise-readiness out of 100, your weakest markers, and the fixes that move them.

Your score out of 100, and the two markers to fix first.

Model Lab

A pre-revenue model you can actually defend. A handful of drivers go in, a 24 month cash curve and your zero-cash date come out. It knows training is R&D, grants are not revenue, and credits run out.

16 months of runway, and the month the credits cliff.

Raise Checklist

The data room list, reorganised around what your lane's investors open first. AI cost splits, token tables, grant files, and the finance section most rooms get wrong.

Your room is 62 percent ready, and what an investor notices first.

Founder Fit

Thirty two questions and two reflections on exit, money, commitment, control and conflict. Invite up to five founders by email. Your answers are never shown to your co-founders. You get one written team reading.

A written reading of where your team aligns, and the talks to have.

Second Opinion

A brutally constructive reviewer for your deck and your model. It reads like the toughest partner in the meeting, then tells you how to fix it.

The three weakest slides, and why.

Time Off Planner

Twelve questions, one honest time off policy. Employees and contractors treated differently, because they are.

Contractors get a billable cap, not an allowance.

Expense Policy

Thirty questions settle cards, receipts, travel and the crypto edge cases before they become arguments.

Gas fees are expenses. Personal wallets are not treasury.

Invoice Generator

A clean invoice in two minutes. VAT aware, crypto friendly, prints straight to PDF.

Reverse charge handled in one toggle.

Data Room

A pre-seed data room checklist that follows you across devices. Track what is missing, in progress and ready, and keep it clean for your raise.

Your room, organised and always with you.
