Omnilex raises $4.5m to scale AI-generated legal commentary
11 November 2025
Omnilex, a Swiss legal research startup, has secured a $4.5m Seed round led by Founderful, with participation from Plug and Play, Tiny Supercomputer Investment Company (TSIC), and Angel Invest. The company is building a reasoning environment that blends laws, court decisions, and commentary so lawyers can work faster and go deeper on complex questions.
The pitch is simple: tap free public legal data, enrich it with AI-generated legal commentary, and deliver precise results. According to Omnilex, this approach can reduce reliance on paid databases by up to 80% while maintaining legal depth. Switzerland and Germany are live; the US and several more countries are in testing.
Traction is notable for an early stage company. Omnilex says ARR doubled over the last three months. More than 120 organizations use the product, including Bayer Pharma and the Swiss Federal Chancellery, alongside legal teams across the DACH region.
What sets it apart
Omnilex positions its core innovation as AI-generated legal commentary-an intelligent layer that automatically annotates, interprets, and connects statutes and decisions across jurisdictions. The team reports more than 200,000 legal annotations created so far.
Marco Henri, Co-Founder and CEO, put it plainly: "Legal commentary exists to help legal professionals understand and apply the law. There will be a future where AI will help create, maintain and connect legal commentary. The most complex cases end up on lawyers' desks, and generic AI models can't help them solve these. We've created an AI system that can, thanks to creating the world's first AI-generated legal commentary."
Why it matters for legal teams
- Research efficiency: precise results that can cut time spent sifting sources.
- Depth: auto-annotations and cross-references help surface relevant reasoning faster.
- Cost pressure: if performance holds, the stated 80% reduction in paid database use will draw attention.
- Coverage: strong European foothold now; US and other jurisdictions in testing.
This is a smart use of public data plus AI. Competition in the US and UK will be intense, but Omnilex's early momentum in Europe suggests a clear product-market fit. Expect larger legal data providers to take note.
