Stilta is a Stockholm-based, Y Combinator (W26) startup building agentic AI for high-stakes patent work. Its platform runs invalidity, infringement, and freedom-to-operate analyses in minutes by deploying networks of AI agents across roughly 180 million patents, 250 million scientific publications, and more than a trillion archived web pages, returning source-backed, auditable claim charts rather than static reports. Founded in December 2025 by four former McKinsey and QuantumBlack engineers, Stilta raised a $10.5M seed led by Andreessen Horowitz and is used by IP firms and in-house teams at large enterprises.
Vetnio is a Swedish AI copilot that automates the paperwork of veterinary medicine. It listens to consultations between vets and pet owners, writes structured clinical notes, drafts client communications, and offers science-backed diagnostic prompts - giving clinicians back roughly two hours a day. Founded in 2024 by longtime friends Arman Karegar and Max Henry Xie, it is one of the few European veterinary companies backed by Y Combinator (W25).
