Background
Josh Passell is the Co-Founder of Cora, an AI fitness coach backed by Y Combinator (W24). He studied Economics at Cornell University.
Josh has spent years immersed in training and fitness technology, and saw the gap firsthand: high-level coaches and sports scientists have access to recovery data, periodization theory, and nutrition frameworks that most everyday athletes never see. He co-founded Cora to close that gap.
His focus at Cora is on the athlete experience — making sure the coaching Cora delivers is grounded in the same principles that real sports scientists use, and that the product feels like talking to a coach who knows your body, not just a calorie counter.
