About Supersign
Open source e-signature infrastructure for teams who value control, transparency, and no vendor lock-in.
Our Mission
Electronic signatures should be accessible, transparent, and free from artificial limits. We believe in empowering teams with the same enterprise-grade infrastructure used by the biggest companies, but without the enterprise pricing or vendor lock-in.
Supersign is part of the Super Family of open-source productivity tools - built for developers, startups, and enterprises who refuse to compromise on control or compliance.
