Since our founding in 2023, we have formed partnerships with leading healthcare organizations and are on track to serve hundreds of thousands of patients on our platform within the next year. We have raised over $35M from a16z and other top-tier VC firms, and on pace to 5x revenue this year.

Our founding team includes experienced clinical and technology leaders from Harvard Medical School, Massachusetts General Hospital, UCSF, the MIT Media Lab, and Mount Sinai. Our small but stellar engineering team (ex-Stripe, NVIDIA, Google DeepMind) is growing fast — and we’re looking for exceptional people to join us at this inflection point.
