Our Mission

Our Story

Cloud Clinic was founded by Dr. Bosty Chan and Hazel Tan in 2020. As a husband-and-wife duo, they bring together more than 10 years of healthcare expertise. It was through their own work and personal experiences that inspired them to build Singapore’s first digital hospital, focused on delivering quality healthcare through innovation.

Sire was founded in 2021 as Cloud Clinic’s first digital department, focused on men’s health. It was first inspired by Dr Bosty’s experiences in the local Urology centres that lack the privacy and sensitivity required for men’s health. Applying digital innovation such as telemedicine, Sire has brought a new experience for men to seek health in a discreet and respectful environment.

Dame was launched in 2023, as a sister spin-off of Sire, focused on women’s health. Dame’s mission is to provide continuous care to empower women to take ownership of their own health, which includes intimate and sensitive healthcare.
