CapSign

What CapSign is

CapSign is a web-based cap table and workflow service for private companies. It supports share class tracking, options, RSUs, vesting, acceleration, 83(b) tracking, ISO $100k limit tracking, dilution scenarios, and fundraising modeling. Companies can keep their register on CapSign, publish public onchain lots, or use a confidential onchain register. CapSign says these onchain registers run on Base Sepolia and will move to Base mainnet with the first verified issuers. Holder names are never public, while a company can choose whether capitalization totals appear on public pages.

For placements, issuers can open Rule 506(b) or Rule 506(c) offerings where investors verify, sign, and pay; closing issues shares to the register. Grant notices, consents, and subscription agreements can be signed by email, and the record updates after the final signature. Companies can import Open Cap Format files, send a provider export for conversion, and export in Open Cap Format at any time. Investors can view shares, options, and SAFEs across companies, sign documents, fund subscriptions by wire, and track vesting and 83(b) deadlines. CapSign supports corporations, LLCs, and limited partnerships, with formation location and currency options. It provides software and does not act as a broker-dealer, find investors, recommend securities, or match buyers and sellers.

Who it suits

CapSign suits private companies that need to manage ownership records, equity awards, governance documents, or fundraising placements. Its investor tools also serve holders tracking interests and deadlines across companies.

Getting started

1. Open https://capsign.com/ in a web browser.
2. Use the free CapSign plan for cap table, claiming, Open Cap Format import/export, e-signatures, and issuer placements.
3. Import an Open Cap Format file or send a current provider export for conversion.
4. Set up the company register and choose its register approach.

Verdict

Choose CapSign if a private company needs cap table records alongside equity, signatures, and placement workflows. Companies seeking a broker-dealer, investor finding, or buyer-seller matching service should look elsewhere; CapSign says it does not provide those services.
