What Ex Nunc Intelligence does

Ex Nunc Intelligence SA is a Lausanne-based (Ecublens) Swiss legal technology company founded in 2023 by co-founders and co-CEOs Kyriaki Bongard and Zoé Berry. The company develops Silex, an AI-powered legal research and productivity platform hosted entirely in Switzerland. Silex indexes over 800,000 Swiss and international legal sources — including cantonal and federal law, international texts, circulars, and curated web content — and updates them daily. Users query the platform in natural language and receive documented responses with relevant legal references in seconds. The platform is designed for legal performance, with explicit hallucination reduction, professional privilege protection, GDPR-compliant data handling, and a zero-learning-on-user-data policy.

The product is sold through two motions: a self-serve product-led growth channel with a 7-day free trial, monthly or annual individual subscriptions (with invoicing available for annual plans), and an enterprise field-sales motion covering multi-seat licenses for large organizations. Named customers include Banque Cantonale de Genève (BCGE), Bordier 1844, Retraites Populaires, Bonnard Lawson International Law Firm, Valfor Avocats, Horizon Avocats, Brodt & Partenaires, and Boivin Sàrl. The company reports 700+ organizations using the platform, 25+ banks and financial institutions in active collaboration, and 70+ additional institutions in discussion or trial. End-markets include law firms, notaries, corporate legal departments, fiduciaries and tax advisors, and regulated financial institutions.

The business has been financed by a CHF 50,000 Digital Seed loan from the Foundation for Technological Innovation (FIT) in June 2024 and a USD 2.15 million pre-seed round in January 2026 led by Spicehaus Partners with Bloomhaus Ventures, Active Capital, Aperture Capital, Core Angels, and angel investors. Reported operational outcomes include a 94% reduction in legal research time, a 56% average increase in cases handled, up to 85% savings on legal database subscriptions, and an 80% reduction in error risk. Headcount is small (1-10 employees). Revenue is not publicly disclosed.

Direct peers

• Luminance: UK-based legal AI platform for contract review, due diligence, and compliance analysis, with strong adoption among corporates and law firms. Comparable in applying domain-specialized AI to legal workflows at enterprise scale.
• Harvey AI: Generative AI platform purpose-built for elite law firms and in-house legal teams, offering legal research, drafting, and analysis assistants. Closest global analogue to Silex in product shape (legal-domain LLM agent) and target buyer (law firms and regulated enterprises).
• Legora: Swedish-founded (formerly Leya) AI legal assistant used by law firms across Europe for drafting and research. Comparable European legal AI peer with cross-jurisdictional content strategy analogous to Silex's Swiss + international indexing.
• vLex: Global legal research platform combining a large multi-jurisdictional case law and legislation database with Vincent AI for natural-language legal Q&A. Directly comparable to Silex on legal corpus + AI agent model, with broader international coverage.
• Spellbook: AI legal assistant for lawyers focused on contract drafting and review, used by thousands of law firms. Comparable product shape (legal-domain LLM assistant) and overlapping SMB/mid-market law firm buyer persona.

Emerging players

• Henchman: Emerging legal AI knowledge management tool that surfaces a firm's prior work product for drafting and research. Comparable in targeting productivity gains for lawyers through AI-driven access to legal knowledge, with a different content anchor (internal precedents vs. statutes).

Broad incumbents

• Thomson Reuters: Owner of Westlaw, Practical Law, and CoCounsel (built on the Casetext acquisition). Dominant legal research incumbent integrating generative AI across its full content corpus and enterprise customer base — the principal threat to any legal AI startup.
• LexisNexis (RELX): Operates Lexis+ AI on top of one of the world's largest legal and news databases, serving law firms, corporates, and government. Comparable to Silex as a legal research + AI assistant, with vastly greater scale, content, and enterprise distribution.
• Wolters Kluwer: Provides legal and regulatory information software (including OneSumX for Finance and legal compliance modules) to banks, insurers, and law firms. Comparable enterprise buyer overlap with Ex Nunc's regulated financial-institution segment.

Regional players

• Weblaw: Established Swiss legal publisher and online legal database operator serving Swiss law firms and courts. Direct regional competitor with deep Swiss legal content and existing enterprise relationships that Ex Nunc must displace or partner with.
