Ex Nunc Intelligence, a Switzerland-based startup building infrastructure for trustworthy legal AI, has secured $2.15 million in an oversubscribed pre-seed funding round.
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.
The funding will be used to further develop the company’s legal intelligence platform, Silex, and expand its underlying technology stack.
Building reliable infrastructure for legal intelligence
Ex Nunc Intelligence was founded by Kyriaki Bongard, Zoé Berry, and Thomas Sèze with the goal of addressing one of the most persistent challenges in legal AI: trust. While AI adoption in legal workflows is accelerating, concerns around unreliable outputs, data leakage, and confidentiality remain major barriers.
The company positions itself not as another point solution, but as a foundational platform for legal intelligence. Its system is designed to support legal professionals across search, reasoning, drafting, and knowledge management within a single, secure environment.
According to co-founder and CEO Kyriaki Bongard, the ambition is to create dependable infrastructure that legal professionals can rely on for high-stakes work, where accuracy, transparency, and confidentiality are essential.
Rebuilding the legal AI pipeline from the ground up
At the core of Ex Nunc’s approach is a vertically integrated legal intelligence architecture. The platform reconstructs the entire upstream AI pipeline, from legal data ingestion and structuring through retrieval, reasoning, and content generation.
Silex combines public legal sources with client-specific materials stored in isolated, secure data environments. This design enables advanced AI-driven analysis while ensuring that sensitive information remains protected and segregated.
By focusing on legal-specific data structures and reasoning workflows, Ex Nunc Intelligence aims to avoid the hallucinations and opacity that often affect general-purpose AI systems used in legal contexts.
Early adoption across the legal sector
Silex is already in active use by several hundred professionals, including law firms, notary offices, and in-house legal teams. Its adoption has been supported through partnerships with established legal institutions and legal technology providers, helping validate its relevance in real-world professional settings.
The platform is positioned as a core workspace where legal knowledge can be searched, analysed, and reused consistently across cases and teams.
Next phase of development
With the new funding, Ex Nunc Intelligence plans to accelerate product development across several areas. These include the rollout of AI agents tailored to specific legal domains, expansion of its proprietary legal knowledge infrastructure, and the launch of a native digital legal publishing layer.
This publishing component is designed to allow legal scholars and practitioners to distribute expertise transparently, with built-in attribution and compensation mechanisms.
