HOW IT WORKS
From inputs to investor-grade constraints in three steps
Enter your numbers
Input your current revenue, operating costs, cash balance, sector, and fundraising target. Everything is based on your actual reality — no estimates, no guesswork.
Run the analysis
The OS runs four valuation methods simultaneously, projects your runway month-by-month, models dilution, and stress-tests your numbers across Downside, Base, and Upside scenarios.
Get non-negotiable constraints
Walk into any investor meeting with a triangulated valuation, a documented runway, and a clear dilution model. No advice. Just the math your decisions must respect.
WHAT IT DOES
A free startup valuation calculator built for founders, not accountants
Most valuation tools give you a single number and call it done. The Founder Decision OS runs four methods simultaneously: DCF, revenue multiples, comparable transactions and asset-based. It then stress-tests every output across Downside, Base, and Upside scenarios.
Who it is for
Pre-seed and seed-stage founders preparing for their first institutional raise. Founders who have been asked for a valuation justification and need a defensible, model-backed answer. Finance leads at early-stage startups who need a quick but rigorous view of the business.
The tool is sector-agnostic and works for SaaS, marketplace, consumer, deep tech, and services businesses. Revenue multiples are calibrated by sector.
What it calculates
- Startup valuation: DCF and revenue multiple methods with scenario ranges
- Runway calculator: Month-by-month cash projection based on your burn rate
- Dilution modelling: Post-money ownership after your fundraising round
- Pre-money valuation: Implied by your target raise and acceptable dilution
- Scenario analysis: three simultaneous scenarios so you know your floor and ceiling
BESPOKE MODELLING
The OS gives you the framework.
We build the model for your situation.
Complex cap tables, non-standard terms, unusual sector multiples. If your numbers don't fit a template, your model shouldn't either. A bespoke build delivers the precision your deal actually requires.
Your numbers, not generic inputs
We work from your actual financials, cap table, and fundraising terms, not placeholder assumptions.
Sector-calibrated valuation
Revenue multiples, DCF discount rates, and comparable benchmarks specific to your industry and stage.
Investor-ready output
A clean, documented model you can share directly with investors, with every assumption visible and defensible.
The numbers that matter, delivered to your inbox.
Periodic dispatches on startup valuation, runway mechanics, and dilution. No advice. No fluff. Just math.
