Run your numbers likeyou mean to raise.
Five finance instruments, free in your browser — LTV, valuation, dilution, runway, SaaS metrics. No signup, no email. When it's time to walk into the room, own the audited Excel + AI stack they're built on.
Try the answer before you buy the artifact.
Each instrument runs the same logic as its Excel model. Use them free with your real numbers — the row numbers are the templates' real indices.
Unit Economicsfree
Does your business model work? LTV, CAC, payback — three scenarios, pass/fail against investor benchmarks.
DCF Valuationfree
What is your company worth? Five-year FCF projection, terminal value, WACC bridge to a per-share number.
Cap Table & Dilutionfree
What will you own after the next round — and take home at exit? Rounds, pool top-ups, preference waterfall.
Startup 3-Statementfree
How long do you have? 24 months of P&L and cash flow — peak burn, runway, and the date the raise is due.
SaaS Metricsfree
Every metric a Series A deck needs, from one MRR waterfall: NRR, Rule of 40, CAC payback, LTV:CAC.
The instrument is free. The artifact is yours.
Buying a model gets you four files that work together — the browser instrument stays free either way.
The audited model
Opens clean in Excel and Google Sheets — no repair prompts, no #REF!. Yellow cells are inputs; everything else is a live formula.
The AI copilot
Paste it into Claude or ChatGPT with your raw numbers — bank balance, invoices, headcount — and get model-ready inputs back, derivation shown.
The quick-start
A five-minute path through the model, an assumptions glossary, and what to check when a number looks wrong.
The live web version
The free calculator you already used — it runs the same logic, so the Excel never surprises you.
The Founder Finance Stack — $199
All five audited models, all five AI packs, all five guides. The complete numbers stack for a raise, for less than two-thirds of à la carte.
Raw numbers to investor-ready, in an afternoon.

Checkout on Gumroad takes a minute. The files download immediately.
Let the AI fill it
Paste the prompt pack and your raw numbers into Claude or ChatGPT, drop the outputs into the yellow cells. The dashboard does the rest.
Fair questions, straight answers.
Why pay when the instruments are free?
The instruments answer the question; the models let you defend the answer. Buying gets you the audited Excel artifact investors will ask for, the AI workflow that fills it from your raw numbers, and the guide that explains every assumption.
Will the Excel work in Google Sheets?
Yes. Every model opens clean in both Excel and Google Sheets — no macros, no add-ins, no repair dialogs.
Do I need finance experience?
No. Inputs are yellow cells with plain-English labels, the guide has an assumptions glossary, and the AI prompt pack turns numbers you already have into the inputs the model needs.
Which one should I start with?
Pre-fundraise: Unit Economics — it tells you whether the machine works. Actively raising: the 3-Statement, or the stack if you'd otherwise buy two or more.
What exactly do I receive when I buy?
Per model: the Excel file, the quick-start guide (PDF), and the companion-AI prompt pack. Delivered instantly by Gumroad after checkout. The stack includes all five of each.
BooferClaus is a design studio too. The finance stack is what happens when a designer who ships gets tired of founders' spreadsheets.
