Youtrust

Youtrust SAS is a French digital-trust company based in Caen, RCS Caen B 794 513 986, founded in 2013 and led by co-founder Alban Sayag as président. It traded as Yousign until 2026, when it renamed to Youtrust — the legal entity kept the same register number, so this is a rename rather than a new company. The name change began in mid-May 2026 and the website moved to youtrust.com in mid-July 2026; application migration runs into 2027.

The rename marks a widening of scope beyond electronic signature. The platform is now organised around three pillars: Sign, covering the three eIDAS levels of electronic signature; Verify, covering identity, document and bank-account (IBAN) verification for anti-fraud and compliance; and Seal, covering electronic sealing for document authenticity. The company states that pricing, contracts and support are unchanged for existing customers.
