Redefine Surgery raises $10M pre-seed for surgical AI, backed by surgeons
What's the deal? Redefine SurgeryDealroom has a profile for this one. Try Dealroom →, a medical technology company building physical AI for surgery, has closed an oversubscribed $10 million pre-seed round backed predominantly by surgeon investors. The funding will support development of its surgical intelligence platform toward commercialisation.
Why now? The raise coincides with Catalyst OrthoScience joining as a Founding Partner. Together, the companies plan to develop an integrated surgical intelligence system connecting data, decisions, and outcomes across shoulder replacement procedures.
What's the endgame? Redefine's platform uses computer vision to help machines understand surgery, creating an intelligence layer for real-time guidance, smarter instruments, and robotic assistance. It is designed to be portable and adaptable across anatomies and workflows, with an initial focus on orthopaedic surgery.
The company calls its approach Collaborative Surgical Intelligence, intended to make expert technique more accessible through the tools surgical teams already use. It is capturing procedures across multiple specialties to train and validate its AI models, guided by a network of more than 25 surgeon advisors.
What could go wrong? The platform remains under development, with commercialisation subject to regulatory clearance and product readiness.
"Closing this round and establishing our partnership with Catalyst are two important steps toward bringing surgical intelligence into everyday practice," said Peter Verrillo, chief executive officer and co-founder of Redefine Surgery. "With Catalyst, we have a partner that shares our belief that the opportunity extends across the full episode of care."
The signal: The round sits above the 95th percentile by size among US health seed-stage deals, a notable figure for a pre-seed raise. It reflects growing investor interest in applying AI and robotics to the operating room — with surgeons themselves footing much of the bill.
