OpenAI invests in Coherence as part of $45 million seed round for brain‑implant cancer detection
OpenAI’s Startup Fund announced an investment in Coherence, a San Francisco startup developing brain‑computer‑interface implants that can read electrical signals linked to brain tumors. The funding is part of a $45 million seed round, and OpenAI says it will not have access to the brain or health data generated by the devices.
Key points
- OpenAI Startup Fund invested in Coherence during a $45 million seed round.
- Coherence’s implant records brain signals for ~30 minutes during tumor surgery to detect cancer activity.
- OpenAI will not receive any brain or health data from Coherence’s devices.
Coherence’s implant was briefly tested in three patients undergoing tumor‑removal surgery at the Royal Melbourne Hospital, recording brain activity for about 30 minutes. The company plans to expand testing to seven more patients and launch a long‑term clinical trial aimed at detecting and treating glioblastoma, with future implants intended for other cancers. The move follows OpenAI’s earlier $252 million investment in Merge Labs, another BCI venture co‑founded by Sam Altman.
