BlockBeats News, May 20th, AI patent startup Stilta announced the completion of a $10.5 million seed round financing. This round was led by Andreessen Horowitz, with participation from Y Combinator and individual investors from companies such as OpenAI, Legora, Sana, Lovable, Listen Labs, among others.

The new funding will be mainly used for recruiting engineers, patent experts, and a marketing team. The company plans to expand its team to about 10 people in the next 3 to 6 months and aims to establish an office in New York by the end of this year or early 2027.

Stilta focuses on AI Agent-driven patent management software, targeting scenarios such as patent infringement detection, patent licensing opportunity discovery, and patent litigation defense. Its platform can analyze hundreds of millions of patents, research papers, and historical web page data to help enterprises and law firms manage patent assets.

The company was founded earlier this year by former McKinsey members Oskar Block, Petrus Werner, Tobias Estreen, and Oscar Adamsson. It was selected for the YC Winter 2026 incubation program. Currently, about two-thirds of its customers come from the enterprise side, with the rest from law firms.

According to reports, Stilta is developing hundreds of AI Agents for tasks such as infringement analysis, patent invalidation analysis, and customizing adjustments for highly specialized fields like pharmaceuticals. In recent years, a16z and YC have been actively investing in the legal tech sector. Previously, a16z has made multiple investments in AI legal assistant Harvey, while YC has recently invested in legal AI companies such as Legora, PointOne, and Parlai.
