Mantle review

Mantle sets its prices by the features you need, not by how many people hold equity, and that is the core of its pitch. Every plan, including the free Starter tier, has unlimited stakeholders and unlimited admin seats, and Starter already handles common shares, options, SAFEs, warrants, notes and RSAs. Founders can issue SAFEs from built-in YC templates with native e-signature and model both SAFE and priced rounds, then export a pro forma cap table for investors. Essentials, at $1,200 per year, adds concierge migration, a one-time cleanup, preferred shares, board resolutions, in-platform exercises and HRIS sync. Growth, at $3,000 per year, adds an annual 409A valuation and SOC 2 Type 2 report access. The gaps show up later in a company's life: ASC 718 expense reporting, Form 3921, QSBS and Rule 701 tracking only arrive on the custom Growth+ tier. For a startup between incorporation and Series A, the combination of a no-cap free plan and published flat prices is the strongest value we compared.
