About Vereign

Swiss trust infrastructure, open source, production-proven

Vereign AG is headquartered in Zug, Switzerland. We built and operate the infrastructure processing 800,000+ verified messages per month in Swiss healthcare — every line of code publicly auditable under AGPLv3+.

Meet the team behind verified trust

Building trust infrastructure for a connected world

Vereign is an infrastructure company. We build the trust layer for regulated digital communication — the layer that verifies identities, signs documents, and makes every exchange auditable. Our platform, Stargate, already processes 800,000+ verified messages per month in Swiss healthcare in partnership with HIN (Health Info Net).

We are headquartered in Zug, Switzerland — Europe's centre for digital trust and decentralised technology. Every line of our code is open source under the GNU Affero General Public License v3 or later, auditable by anyone, and hosted on our own infrastructure.

Our trajectory: from research in self-sovereign identity and Gaia-X contributions to production deployment in Swiss healthcare — and towards the institutional trust infrastructure that regulated industries across Europe need. The proof of concept is behind us. The deployment phase begins now.
