CapSign

What CapSign is

CapSign provides private companies with a cap table of record and workflows for equity, governance, and fundraising. Companies can track share classes, options, RSUs, vesting, acceleration, 83(b) deadlines, and the ISO $100k limit; the product also lists dilution scenarios and fundraising modeling. A company can keep its register on CapSign, publish public onchain lots, or use a confidential onchain register. CapSign says holder names are never public, and capitalization totals appear on public pages only if the company chooses. It says onchain registers currently run on Base Sepolia and are intended to move to Base mainnet with the first verified issuers.

For private placements, issuers can open Rule 506(b) or 506(c) offerings where investors verify, sign, and pay; shares are added to the register at closing. Grant notices, consents, and subscription agreements can be signed by email, with records updated after the final signature. Companies can import Open Cap Format files or provide an export from a current provider for conversion, and can 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. The free plan is listed as free; paid pricing is available on request.
