What Stilta does

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.

Agentic AI for intellectual property

What is your company going to make? Please describe your product and what it does or will do.

We build agentic AI software to help patent attorneys analyze, challenge, and enforce patents. Our tool runs advanced searches and audits patent landscapes at a scale manual methods can't reach. Every result is source-backed and auditable, making it suitable for high-stakes IP litigation work.

Where do you live now, and where would the company be based after YC?

We currently work remotely across locations. After YC, we plan to base the company where it best supports our engineering and IP law firm customers, likely still remote or hybrid.

Explain your decision regarding location.

We want to stay flexible to access global talent and serve international law firms who need Stilta. The remote model fits the expertise we require and our users' distributed teams.
