About Stilta

Stilta builds agentic AI software for intellectual property, starting with patent litigation. Whether challenging or enforcing a patent, leading IP law firms and in-house IP teams use Stilta for source-backed, auditable analysis. Innovation drives the world's most important breakthroughs, but the tools that protect it haven't kept pace. Patent attorneys do high-stakes work with a process still built on manual document review and disconnected point solutions. Generative AI helps with drafting, but it doesn't deliver the trust and transparency that legal-grade work demands - no sources, no traceability, no audit trail. Stilta takes a different approach. We use agentic AI to run search and analysis at a scale manual methods can't match, with every output source-backed, referenced, and auditable. Until recently, this wasn't technically possible. We're four engineers from McKinsey/QuantumBlack who built and deployed AI systems at some of the world's largest organizations. With Stilta, we're equipping the people who protect the world's most valuable ideas with tools that match the stakes.
