Ex Nunc Intelligence Secures €1.8M to Build the “Infrastructure Layer” of Legal AI

• ByStartupStory     |    January 14, 2026

In a definitive move to shift LegalTech from generic productivity tools to professional-grade infrastructure, Lausanne-based startup Ex Nunc Intelligence has successfully closed an oversubscribed €1.8 million ($2.15 million) pre-seed funding round. Announced on January 12, 2026, the investment highlights a growing demand for “AI-native” legal systems that prioritize data sovereignty and professional secrecy over simple automation.

The round was led by Spicehaus Partners, with significant participation from Bloomhaus Ventures, Active Capital, Aperture Capital, Core Angels, and a syndicate of strategic angel investors.

Silex: Moving Beyond the “AI Wrapper”

While many current LegalTech solutions function as “wrappers” around off-the-shelf Large Language Models (LLMs), Ex Nunc has built its Silex platform from the ground up. The company focuses on a vertically integrated legal intelligence stack—re-engineering everything from data ingestion and legal structuring to reasoning and generation.

Key Features of the Silex Platform:

• Isolated Data Silos: Addressing the legal industry’s primary barrier to AI—confidentiality—Silex allows law firms to connect private internal knowledge bases with public legal sources within secure, isolated environments.

• No Hallucinations: Every response generated by Silex is grounded in explicit, traceable legal sources. If the law does not allow for a definitive conclusion, the system is designed to state uncertainty rather than speculate.

• Proprietary Pipeline: The platform uses a specialized legal intelligence stack designed for legal logic, ensuring that internal documents are transformed into structured, reusable strategic assets.

“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.” — Kyriaki Bongard, Co-founder and CEO of Ex Nunc Intelligence.

Strategic Roadmap: Specialized Agents & Digital Publishing

The new capital is earmarked for an aggressive expansion of the Silex ecosystem through 2026 and 2027:

1. Domain-Specific AI Agents: Rolling out a new generation of specialized AI agents tailored to specific areas of law (e.g., Intellectual Property, Mergers & Acquisitions, and Tax).

2. Digital Publishing Layer: Introducing a native digital legal publishing layer within Silex. This will enable legal scholars and practitioners to publish doctrinal content directly on the platform with transparent compensation models.

3. European Expansion: Scaling the verified legal knowledge infrastructure across multiple European jurisdictions.

Market Traction and Institutional Support

Founded in 2022 by Kyriaki Bongard (CEO), Thomas Sèze (CTO), and Zoé Berry, Ex Nunc emerged as the first LegalTech spin-off from EPFL (École Polytechnique Fédérale de Lausanne). The platform is already utilized by several hundred law firms, notary offices, and corporate legal departments across Switzerland and Europe.

Pascal Stürchler, CEO of Bloomhaus Ventures, noted that the startup is solving one of the hardest problems in the sector: building AI that lawyers can truly trust. By combining deep legal domain expertise with top-tier AI engineering, Ex Nunc is positioning itself as the “backbone” of the future legal office.
