About

Stilta is an AI platform automating intellectual property research and analysis: users input a patent number and relevant content, and AI agents search for conflicting patents, identify similar properties, and compile filing and court histories 1. The platform aims to lower costs in patent litigation, enabling companies to analyze and enforce patents previously shelved due to prohibitive expenses 1. The $10.5M Seed announced May 19, 2026 was led by Andreessen Horowitz with participation from Y Combinator and operator-investors from OpenAI, Legora, and Lovable 1.

What Founders Say

Oskar Block, CEO, said of Stilta’s AI architecture: “They reason in parallel and converge the way a room full of specialists would, but at a scale no human team can match.” 1

Block on the broader implications: “The question isn’t really whether the legal system is prepared for AI. It’s whether companies are prepared for what becomes possible when the analytical bottleneck disappears.” 1
