deepblock is a LegalTech firm specialized in digital transformation and in crafting bespoke information systems tailored for the legal industry, among others.

Established in 2017 by the dynamic duo of Christophe LEMÉE, an innovative engineer, and Jean-Philippe TOUATI, a seasoned lawyer from the Paris Bar, deepblock is the result of a combination between deep learning and blockchain technologies.

For the past seven years, deepblock has been busy developing a suite of functional modules that embody their commitment to transparency and digital sovereignty. Highlights from their suite include:

  • RNSV (Registre National des Signatures Visuelles), powered by a proprietary AI neural network
  • A robust eIDAS-compliant electronic signature engine
  • A comprehensive Intellectual Property management service
  • An OpenLogs DLT (Distributed Ledger Technologies) register using their own Open Technology layer

deepblock’s cutting-edge modules are API-friendly and have found applications across a diverse range of platform editors, catering to both the private and public sectors.

Today, deepblock is powered by a team of dedicated professionals spread across three strategic locations:

  • Their headquarters in the heart of Paris
  • Their research and development hub in Bagneux
  • Their project management teams located in Chessy

Solution Description

deepblock has developed an eIDAS-compliant e-signature service that integrates with Entrust Remote Signing Service to provide professionals with eIDAS qualified signing capabilities, without the need to host secure hardware such as USB tokens. This combined solution enables professionals of all industries – including notaries and lawyers – to generate e-signatures that have the highest level of assurance across the European Union.
