Anish Mariathasan is Co-Founder of Osseus (YC S26), the intelligent development platform for robotics that helps engineering teams manage complex cross-disciplinary dependencies using AI agents.

Anish holds an MEng in Biomedical Engineering from Imperial College London and turned down an Oxford PhD in AI for Health to pursue entrepreneurship full-time.

He previously co-founded a compliance AI startup and conducted ML research at a Harvard-HKU joint lab focused on computer vision for cancer research, giving him a rare blend of deep AI and hardware intuition.

Osseus was accepted into Y Combinator's Summer 2026 batch, validating the team's vision to build a live dependency graph that traces the downstream impact of hardware changes across mechanical, electrical, and software systems.

Osseus is positioned at the frontier of the booming robotics sector, offering teams an AI-powered design review platform and component marketplace that accelerates prototyping and reduces costly engineering iteration cycles.
