Ex Nunc Intelligence, a Lausanne-based LegalTech company behind the Silex platform, has closed an oversubscribed €1.8 mn pre-Seed round to build what it describes as infrastructure for legal intelligence rather than another point solution for lawyers.
The round was led by Spicehaus Partners, with participation from Bloomhaus Ventures, Active Capital, Aperture Capital, Core Angels, and a group of individual angel investors.
Kyriaki Bongard, co-founder and CEO of Ex Nunc Intelligence, said the company is focused on building systems lawyers rely on, not experimental tooling layered on top of generic AI. She framed the ambition around trust, durability, and infrastructure rather than features or speed.
Pascal Stürchler, co-founder and CEO of Bloomhaus Ventures, said Ex Nunc Intelligence is tackling one of the most difficult challenges in LegalTech, building AI systems lawyers accept as dependable. He pointed to the team’s mix of legal expertise, AI engineering depth, and early market traction.
Founded in 2022, Ex Nunc Intelligence positions itself as natively legal and natively AI, rather than a legal product adapted from general-purpose models.
A central differentiator is its ability to combine public legal sources with each client’s private knowledge base through secure, isolated data silos. Law firms and legal departments can connect internal documents without exposing sensitive information across clients or models.
That architecture targets one of the main blockers to AI adoption in legal work: data protection and confidentiality. Internal documents become structured, reusable knowledge assets rather than static files locked in document management systems.
While many legal AI products rely on off-the-shelf models and standard preprocessing, Ex Nunc Intelligence says it has built a proprietary legal intelligence stack end to end.
The system covers ingestion, legal structuring, retrieval, reasoning, and generation, with models and pipelines designed specifically for legal logic rather than generic text handling.
Bongard said the company sees AI as a way to extend legal expertise, preserve institutional knowledge, and turn both public and private legal information into a strategic asset, not as a substitute for legal judgment.
The new funding will accelerate development of Silex, support the rollout of specialised AI agents focused on specific areas of law, and expand the platform’s legal knowledge infrastructure.
Ex Nunc Intelligence is also building a native digital legal publishing layer within Silex, allowing scholars and practitioners to publish doctrinal content directly on the platform with clearer and more transparent compensation models.
Silex is already used by several hundred law firms, notary offices, and corporate legal departments. The company says every response generated by the platform is grounded in explicit legal sources, with no speculative output, a design choice aimed squarely at professional legal use rather than general productivity.
Strategic partnerships with legal institutions and technology providers continue to support adoption, reinforcing Ex Nunc Intelligence’s positioning as infrastructure rather than another short-lived LegalTech application.
