Mantle is the cap table platform that’s free to start and fair as you grow.
Mantle Starter costs nothing and gives you unlimited stakeholders, SAFE issuance and e-signing, and scenario modeling. Track options, warrants, RSAs, SAFEs, and common shares in one place.
Paid plans add preferred shares, 409A valuations, in-platform exercising, and concierge onboarding from your spreadsheet or current provider. Pricing is flat, so your bill doesn’t jump because you hired or raised a round.
