Swiss Startup Ex Nunc Intelligence Raises $2.15M To Improve Trust In Legal AI

The company aims to solve reliability and trust problems in legal AI through its platform, Silex.

Ex Nunc Intelligence was founded by Kyriaki Bongard, Zoé Berry, and Thomas Sèze to provide reliable legal intelligence, serving as a core platform where professionals can search, reason, draft and manage knowledge.

The founders created the company to tackle AI’s biggest challenges in law: untrustworthy outputs and risks to confidentiality. With deep expertise in both law and AI, Ex Nunc delivers secure professional grade intelligence tailored for legal work.

“Our ambition is not to build another legal tool, but to create the underlying infrastructure that will power the next era of legal intelligence. Legal professionals need systems they can trust. That is what we are building,” said Kyriaki Bongard co-founder and CEO.

Ex Nunc’s technology is a legal intelligence platform that rebuilds the entire upstream pipeline from data ingestion and legal structuring to retrieval, reasoning and content generation. It integrates public legal sources with client specific knowledge stored in secure silos, protecting sensitive information while enabling advanced, intelligent processing that sets it apart from other solutions.

Silex is already used by several hundred professionals across law firms, notary offices and corporate legal teams with its impact validated through strategic partnerships with leading legal institutions and technology providers.

The new funding will accelerate Silex’s development, introduce AI agents for specialized legal areas, expand the underlying legal knowledge infrastructure and launch a native digital legal publishing layer for scholars and practitioners with transparent compensation.
