Stilta Raises $10.5M to Bring AI Agents to Patent Law

Stilta, a Stockholm-based AI startup, raised $10.5 million in seed funding led by Andreessen Horowitz to automate patent litigation and intelligence workflows for enterprises and law firms.

The raise signals a broader shift in how companies approach intellectual property. Patents represent a largely untapped asset class, and AI is now making the analysis required to enforce and monetize them faster and more accessible.

The Problem

Over 90% of S&P 500 company value is intangible, yet most patents are never enforced, licensed, or monetized. The reason is not a lack of evidence. The analysis required to surface that evidence has historically been too complex and too expensive for most organizations to pursue at scale.

Patent litigation workflows have not changed significantly in decades. Attorneys spend large portions of their time on manual document review, prior art searches, and freedom-to-operate assessments that can take months to complete.

What Stilta Does

Stilta builds AI agents that reason across 180 million patents, 250 million scientific publications, and over a trillion archived web pages. The platform helps companies defend against patent assertions, identify licensing opportunities in existing portfolios, and clear paths to commercialization. Every finding is traced to a specific source document.
