Mantle SAFEs

Mantle SAFEs lets founders and investors create, send, and sign Simple Agreements for Future Equity (SAFEs) within a single web platform without requiring a separate electronic‑signature service. Users can select from built‑in Y Combinator templates or upload their own, and the system visualizes how different financing scenarios would affect dilution in future rounds. The tool updates the company’s cap table and data room automatically once a SAFE is signed, and it supports an unlimited number of stakeholders on the free “Mantle Starter” plan, which does not require a credit card.

The service is aimed at early‑stage companies and their investors who need a quick, cost‑free way to issue SAFEs and keep equity records current. It combines document generation, in‑platform signing, and real‑time equity modeling in one interface. The platform also integrates with Mantle’s broader equity‑management features, such as 409A valuations and round calculators, providing a unified environment for fundraising and cap‑table maintenance.
