Lausanne-based Ex Nunc Intelligence, the developer of a LegalTech platform Silex, has today announced the closing of an oversubscribed pre-Seed round of €1.8 million ($2.15 million) to create the infrastructure layer for legal intelligence.
The round was led by Spicehaus Partners, with participation from Bloomhaus Ventures, Active Capital, Aperture Capital, Core Angels, and a group of angel investors.
“Our ambition is not to build another legal tool, but to create the underlying infrastructure that will power the next era of legal intelligence,” said Kyriaki Bongard, co-founder and CEO of Ex Nunc Intelligence. “Legal professionals need systems they can trust. That is what we are building.”
In the context of 2025 European LegalTech funding activity, Ex Nunc Intelligence’s pre-Seed round sits among a steady flow of early-stage investment into AI-driven legal infrastructure and workflow tools.
In the Netherlands, Saga raised more than €1.5 million to expand its lawyer-centric AI platform beyond Europe, while Denmark-based Pandektes secured €2.9 million to automate legislative navigation across jurisdictions. In the UK, Augmetec closed a Seed round of over €2.4 million to develop its investigative and regulatory legal platform, while Italy’s Lexroom.ai raised €2 million to advance a vertical generative-AI solution for legal research and document work.
At the growth end of the spectrum, Sweden-based Legora attracted €70.6 million in Series B funding to scale its collaborative AI tools for law firms and in-house teams.
Taken together, these rounds represent approximately €79 million in LegalTech investment in 2025 alone. Against this backdrop, Ex Nunc Intelligence’s pre-Seed round is comparable in size to other early-stage raises in the sector, particularly those focused on AI-assisted legal knowledge and workflows, and reflects continued capital allocation towards trusted, domain-specific legal AI platforms in Europe.
“Ex Nunc Intelligence is solving one of the hardest problems in legal tech: building AI that lawyers can truly trust,”, says Pascal Stürchler, co-founder and CEO of Bloomhaus Ventures. “With a rare combination of legal domain expertise, top-tier AI engineering, and early traction, the team is well positioned to build core infrastructure for the future of legal work.”
Founded in 2022, Ex Nunc Intelligence is paints themselves as one of the first companies truly native to both law and AI, rather than a legal product built on top of generic AI. A key differentiator of Ex Nunc Intelligence is its ability to combine public legal sources with each client’s private knowledge.
Through secure and isolated data silos, law firms and legal departments can reportedly connect internal documents without compromising confidentiality.
This architecture addresses one of the main barriers to AI adoption in law: data protection, while transforming internal documents into structured, reusable, and strategic knowledge assets.
Where most legal AI tools wrap off-the-shelf models and apply standard preprocessing, Ex Nunc Intelligence says they combine deep legal expertise with advanced AI engineering to design truly intelligent legal processing pipelines.
The company has built a proprietary legal intelligence stack, designing its own models, a full-stack approach and architecture from data ingestion and legal structuring to retrieval, reasoning and generation.
“At Ex Nunc Intelligence we believe that where AI can truly make a difference in the legal sector is not by replacing lawyers, but by augmenting their expertise, securing their knowledge, and transforming both public and private legal information into a strategic asset,” added Kyriaki in a public statement.
This new funding will accelerate the development of Silex, support the rollout of a new generation of specialised AI agents dedicated to specific areas of law and the expansion of its legal knowledge infrastructure.
As part of this roadmap, Ex Nunc Intelligence is also developing a native digital legal publishing layer integrated into Silex, enabling legal scholars and practitioners to publish doctrinal content directly within the platform, while ensuring transparent and improved compensation models for authors.
The platform Silex is currently used by “several hundred law firms, notary offices, and corporate legal departments, underscoring strong demand and market validation“. Unlike generic digital tools, Silex is built specifically for professional legal use, with every answer grounded in explicit legal sources and no speculation.
This growth is further supported by strategic partnerships with key legal institutions and technology providers, accelerating market adoption and reinforcing Ex Nunc Intelligence’s position as a trusted infrastructure partner for the legal sector.
