Cursor for patent practitioners

Stilta is the AI-native software for patent practitioners, built on agentic workflows to amplify how IP work is done end-to-end. Instead of spending weeks manually researching and analyzing patents, practitioners can reduce manual work by up to ~60% while unlocking new revenue opportunities. Innovation is key to solving the world’s most important challenges, but the tools to protect innovation haven’t kept up. Patent teams are stuck doing high-stakes work with a process built around manual document review and disconnected point solutions. Existing tools are rigid and fail by not integrating AI with clear traceability (every output must be source-backed, referenced, and auditable). General LLM solutions generate text, but they don’t solve trust and integration in legal-grade workflows. We’re four engineers from McKinsey/QuantumBlack who’ve spent the last few years building and deploying AI for large organizations. Now we are building Stilta because the practitioners protecting the world’s most valuable ideas deserve tools that match the stakes. We’re already live with leading firms in both Europe and the US.

Problem

Missing the right patent, or getting the analysis wrong, can cost billions. That’s why patent practitioners spend a large share of their time reading technical documents and building arguments. LLMs can generate text, but patent work has non-negotiables that most tools still don’t meet.

  • Research is manual: practitioners spend hours searching and analyzing to find the few patents that matter
  • Tools produce static reports: most solutions generate a final document or flat lists instead of interactive, argument-led analysis that adapts
  • Context gets lost: teams lack flexible end-to-end tools, resulting in a fragmented and clunky software stack
  • AI isn’t trusted without evidence: in patent work, outputs must be traceable to specific references with clear rationale

Solution

We've built Cursor for patent practitioners, using agentic AI to improve how high-stakes patent work is done end-to-end. Our agentic approach works alongside you, iterating on analysis rather than producing one-time reports. Specialized agents with deep domain and skills expertise handle complex patent analysis while building context from your documents and prior work. This enables deeper and more granular analysis that was not previously technically feasible.

Whether you're searching for prior art, analyzing portfolios, or monitoring for infringement, you get interactive litigation analysis you can build on - not flat lists. We're already live with leading firms in both Europe and the US.

Why this matters

Innovation is key to solving the world’s biggest challenges, but protecting innovation is still slowed down by manual, fragmented workflows. Patent practitioners should be able to move at the pace of innovation, so great ideas turn into durable competitive advantage.

Who we are

We’re four engineers and previous founders who met at McKinsey/QuantumBlack and spent the last few years building and deploying AI for large organizations. We saw first hand how the IP world has one of the largest gaps between available tools and what's needed - the perfect match for what we've built our expertise to solve.

  • Tobias previously led AI projects at QuantumBlack and Netlight (and once turned down a pro League of Legends contract).
  • Petrus is a builder who’s spent the past 5 years scaling AI systems at QuantumBlack and AWS.
  • Oskar founded and bootstrapped two startups to +$1M ARR in parallel to working at McKinsey & Goldman Sachs.
  • Oscar competed nationally in Math, lead product development at unicorns, and worked with +50 CEOs at McKinsey.

Our ask

If you know patent practitioners who'd benefit from faster, better, and more interactive research, we'd love an intro.
