Stilta builds an AI-driven platform that automates the research and analysis behind patent and intellectual property cases, using a network of AI agents to search for conflicting patents, flag similar property, and pull filing and court histories. The software returns litigation-grade outputs including reports and claim charts with pinpoint citations. The company was founded by Oskar Block, Tobias Estreen, Petrus Werner and Oscar Adamsson, with Block serving as CEO. Stilta raised a $10.5 million seed round led by Andreessen Horowitz and supported by Y Combinator and operators from OpenAI, Legora, and Lovable, which establishes its current financial runway. It competes with other legal-tech entrants like Solve Intelligence and DeepIP. The startup aims to make patent analysis more efficient and affordable so companies can better realize latent value in their patent portfolios.
