Digital sovereignty for everyone

Digital interactions depend on mutual trust. We are a bunch of like-minded people who think that this can be achieved with openness, transparency and decentralised technology.

Our vision is therefore to empower individuals and companies alike by adding a self-sovereign layer of trust and evidential value to their day-to-day communications.

Easily usable for everyone, secure and with privacy-by-design.


We partner with the best

We can't do this alone. We collaborate with the best partners sharing our vision.


Together, we are Vereign

We are an international team with experienced founders of diverse backgrounds. Among us are software visionaries, successful business specialists and experienced advisors from law and IT security. Together we solve complex challenges and make Vereign happen!
