CapSign
What it is
CapSign provides private companies with a web-based cap table of record and workflows for equity, governance, and fundraising. Companies can track share classes, options, RSUs, vesting, acceleration, 83(b) status, and ISO $100k limit tracking. They can import Open Cap Format files or have a current provider export converted, then export in that format at any time. Companies may keep their register on CapSign, publish public onchain lots, or use a confidential onchain register. CapSign says its onchain registers run on Base Sepolia and are intended to move to Base mainnet with the first verified issuers. Holder names are not public, and capitalization totals appear on public pages only if a company chooses. Issuers can open Rule 506(b) or 506(c) placements where investors verify, sign, and pay; shares are issued to the register at closing. Investors can review holdings across companies, sign documents, fund subscriptions by wire, and track vesting and 83(b) deadlines. The listed CapSign plan is free and includes cap table, claiming, Open Cap Format import/export, e-signing, and issuer placements.
