Fidji Simo, who left OpenAI in July 2026 as CEO of Applications/AGI deployment after a seven-year battle with Postural Orthostatic Tachycardia Syndrome, gave her first interview since departing and described ChronicleBio, the startup she cofounded with Rohit Gupta and Rishi Reddy. In its first year the Menlo Park company performed 890 blood draws from 709 patients in Utah, Arizona, Texas and India, holds over 3,500 blood tubes in a biobank, and has extracted 153 terabytes of biological data; it has raised $15 million. Using a mix of OpenAI and Anthropic models, it says it has identified five biologically distinct sub-diseases within POTS and plans to test existing drugs on those subgroups before the end of 2026. On Aug. 11, 2026 it opens sign-ups for mobile phlebotomy home blood draws across the U.S., free for the first 250 participants and $400 thereafter, with results returned to patients in exchange for their data.
