Stilta, a nascent entrant in the legal technology sector, has quickly drawn significant attention from venture capital. The Stockholm-based startup, which is just five months old, recently secured a $10.5 million seed funding round spearheaded by Andreessen Horowitz, a renowned name in venture capital circles. Founded in December 2025 by former McKinsey engineers, Stilta claims that its AI agents can take on key challenges in patent litigation such as invalidity and infringement analysis.
To gain deeper insight into Stilta’s workings, visit their website. The company’s agents reportedly have the capability of navigating an expansive database consisting of 180 million patents, 250 million scientific publications, and over a trillion archived web pages. This is facilitated through an integration with the Internet Archive’s Wayback Machine, aiding in thorough prior art searches essential for invalidity assessments. For a firsthand understanding of its competitive landscape, Stilta’s CEO highlighted Patlytics and Solve Intelligence’s Charts product as their closest competitors.
The funding boost enables Stilta to embark on hiring beyond its founding team and aims at establishing a physical presence in New York by year-end. Notably, the AI landscape for patent practitioners is expanding rapidly, with recent developments like Patlytics securing $40 million in Series B funding and Solve Intelligence following suit.
CEO Oskar Block demonstrated the system’s capabilities, explaining how users could drop in a patent number, triggering multiple AI agents to perform intensive searches for prior art. Its platform not only supports invalidity analyses but also infringement reviews and freedom-to-operate inquiries, allowing collaborative project engagement for legal teams. For those interested in Oskar Block’s professional background, more information is available on his LinkedIn profile.
As per the company press release, Stilta is also establishing substantial traction within the enterprise sector, signing up several notable clients, including top-tier corporations like Roche, Alfa Laval, and Maersk.
