Stilta, an AI company focused on patent litigation and intelligence, announced $10.5 million in funding led by Andreessen Horowitz, with participation from Y Combinator and founders and operators from leading AI companies including Sana, Legora, OpenAI, Lovable, and Listen Labs.
Founded in 2026, Stilta develops agentic AI software designed to help enterprises enforce, defend, and commercialize patents. The platform analyzes more than 180 million patents, 250 million scientific publications, and over a trillion archived web pages to uncover evidence that traditional patent review systems and manual analysis may overlook. The company said its software enables organizations to defend against patent assertions, identify commercialization opportunities, and uncover hidden value within patent portfolios while maintaining traceability to source documents.
The company noted that patents remain one of the most underutilized asset classes in business, despite intangible assets accounting for more than 90% of S&P 500 value. Stilta aims to reduce the complexity and cost traditionally associated with patent enforcement and monetization.
Since launching in February 2026, Stilta said it has signed enterprise customers and pilot programs, including Roche, Alfa Laval, and Maersk, along with three of the five largest intellectual property firms globally.
The funding will be used to expand the company’s team across Stockholm and New York, including hiring engineers, go-to-market personnel, and patent experts. Stilta’s four founders previously worked in McKinsey & Company’s AI practice before launching the company.
KEY QUOTES:
“When one company starts using AI for patent enforcement, every competitor has to follow. That shift is happening right now. We built Stilta to be the platform IP teams reach for when the stakes are highest, and to make sure no invention worth protecting goes unprotected.”
Oskar Block, Co-Founder And CEO, Stilta
“When you can analyze more than 10x more patents to find critical commercialization risks, you don’t just get more efficient — you get better decisions. Our attorneys can focus on partnering with our clients on what matters most, backed by top tier FTO assessments protecting them from costly infringement risks.”
Joakim Hernström, CEO, Bergenstråhle And Partners
“Patent litigation runs on labor-intensive workflows that haven’t meaningfully changed in decades. Stilta automates them and, in doing so, becomes the system of record for how enterprises protect and monetize their most valuable intangible assets.”
David Haber, General Partner, Andreessen Horowitz
