About CapSign

Building the registry of private companies

Public companies have transfer agents and a shared record of who owns what. Private companies have spreadsheets, PDFs, and a vendor login. We think every private company deserves a register of record, and that it should be free.

Why we exist

Ownership is the most important record a company keeps

A cap table decides who gets paid in an exit, who votes on a merger, and whether an employee's options are worth anything. Yet for most private companies it lives in a spreadsheet, or in a system that charges by the seat and makes it hard to leave.

CapSign started in 2023 to fix that. We built a register that companies keep as their record of ownership, with the grants, consents, and raises that change it all in the same place. Then we made it free, and gave every private company a public page it can claim.

The result is a public directory where Verified on CapSign means the company keeps its live register here, and where holders, investors, and counsel can trust the numbers they see.

What we believe

Four principles we build by

The record should be trusted

Verified means something specific: a confirmed officer and a live register. We don't sell badges and we don't rank companies.

Your data is yours

Open Cap Format in and out. If we ever stop earning your trust, you should be able to leave in an afternoon.

Holders deserve the truth

Every employee and investor should be able to see what they own, and the signed document that says so.

Software, not a broker

Companies run their own offerings with their own investors. We build the tools and keep out of the deal.
