Scobleizer · x · 2026-11-13
Investor lpolovets announced co-leading an $8M seed round (with Inflect) for 4D Surgical's public launch. The startup builds robotic arms that can operate inside MRI machines — a combo previously impossible because conventional robots fail near strong magnetic fields — letting surgeons see inside the living brain in real time and precisely guide treatments, with potential to transform care for Parkinson's, epilepsy, and Alzheimer's.
