About

Certainly Health is a San Francisco-based healthcare price transparency marketplace — backed by Y Combinator (S23) with $2.3 million in seed funding in December 2023 from Pacific 8 Ventures, Y Combinator, institutional investors, and angels — providing patients with a doctor booking platform that shows upfront out-of-pocket costs using machine learning to predict and guarantee healthcare spending before appointments, addressing the surprise medical bill crisis where 57% of Americans have received unexpected bills and 38% delay care due to cost uncertainty. Founded in 2023 by Daryl Sew and Kevin Chiu (Stanford graduate, former Uber engineer, and Uber Health founding member who grew that program to $100 million in 2 years), Certainly Health enables patients with insurance to book doctors while seeing the actual cost they will owe — not the sticker price.
