Cap tables should be a free feature, not a $5,000 subscription.
CaptableAI is built by Fairmint, a steward of the Open Cap Table Format and the Open Cap Table Protocol. We think equity records belong in an open standard, held by the company that owns them, readable by any tool, and increasingly driven by the AI assistant you already have open.
Open by default
Your cap table is stored as schema-conformant OCF. Export it and import it anywhere that supports the standard. Leaving costs you a download.
Verifiable, not just stored
Anyone can hold a spreadsheet. We reconcile every object against the documents behind it, so what you show an investor is provable.
Where you already work
A cap table you touch twenty times a year shouldn't need its own login. Connect it to your assistant and ask.
The standards we build on
Three open standards do the heavy lifting. None of them are ours alone, and that's the point.
Open Cap Table Format
The machine-readable schema for equity data. It's how your cap table is stored, exported and verified. Coalition site →
Open Cap Table Protocol
Onchain issuance and transfer, for teams that want every stakeholder to hold a verifiable view of what they own.
Model Context Protocol
The open standard that lets any AI assistant call our tools. It's why you don't need our app. About MCP →

Messy is normal. Run the free check, or spend 30 minutes with someone who has seen worse.
