Overview
Aidy is a YC W24, San Francisco-based digital health startup whose current public product is an SMS-first and app-based companion for people with Crohn’s disease and ulcerative colitis. It helps users track symptoms, diet, meds, biologic schedules, and coverage requirements, then turns that data into reports and support for care teams; Aidy monetizes through B2B partnerships with health plans, employers, researchers, pharma patient-services teams, medical affairs/HEOR groups, and specialty pharmacies. Public records also show earlier Aidy/grants/policy pivots, so older traces should be treated carefully.

Work & culture
Public signals point to a very small, fast-moving, patient-centric team that emphasizes privacy, low-friction workflows, evidence-based content, and frequent product shipping. The company also appears to work closely with creators and patient communities.
Compensation
No public employee salary bands or equity/bonus details were found. A June 2026 creator-interest form says creator collaborations are paid, but that is not a general employee compensation signal.
