CapSign vs Mantle

CapSign is a web-based cap table of record for private companies, combining equity, governance, and fundraising workflows. Companies can track share classes, options, RSUs, vesting, acceleration, 83(b) activity, ISO $100k limit tracking, dilution scenarios, and fundraising modeling. Registers can remain on CapSign, use public onchain lots, or use a confidential onchain register. CapSign says onchain registers run on Base Sepolia and will move to Base mainnet with the first verified issuers. Holder names are never public, while capitalization totals appear publicly only when a company opts in. Issuers can open Rule 506(b) or 506(c) placements where investors verify, sign, and pay, with shares issued at closing. Email signatures update records after the final signature. Companies can import or export Open Cap Format files. Investors can review holdings, sign documents, fund subscriptions by wire, and track vesting and 83(b) deadlines. Pricing is on request.
