Fundraising,
minus the guesswork.
FounderOS is the operating system solo founders use to read term sheets in minutes, model dilution before it happens, and keep every investor conversation moving, without a finance team.
You're raising capital with a finance team of one.
Term sheets are written to be skimmed, not understood. Cap tables get messy the moment a second SAFE shows up. And most founders find out their dilution number after it's already signed.
One system. Every step of the raise.
Five tools that plug into each other, so a clause you flag in a term sheet updates your cap table automatically.
Term Sheet Analyzer
Upload any term sheet and get every clause explained in plain English. Liquidation preference, anti-dilution, board control, each flagged by risk level before you sign anything.
Cap Table Simulator
Model every round, SAFE, and option pool before it happens. See your ownership at exit, not just today.
Investor Board
Track every conversation, from first email to signed check, in one pipeline built for solo founders.
MRR Trends
Connect your revenue and watch the number every investor asks for, updated in real time.
AI Co-Founder
Ask the hard questions out loud. Dilution math, investor objections, what a clause actually costs you, answered against your own numbers.
From upload to understood, in one sitting.

I found a 4x liquidation preference in a term sheet I almost signed. FounderOS paid for itself in the first upload.
Priced for founders, not finance teams.
Before you ask.
FounderOS explains what's in a term sheet so you can negotiate with confidence. It's not a substitute for legal counsel on final signature, but most founders use it to know exactly what to ask their lawyer.
