Our Story

Dr Bosty Chan is a Singapore-born doctor who founded Sire based on his real-life experiences from working in the local Urology department. Through his training in Tan Tock Seng Hospital and Sengkang General Hospital, he had the chance to witness firsthand the struggles Singaporean men were facing regarding their “private areas”.

Prior to Sire, Dr Bosty has been involved in the healthcare startup scene. He is the founder of Lokuns, which currently maintains Singapore’s largest community of General Practitioners (GPs). He also worked at TrustScan, a local COVID-passport aggregator during the peak of COVID-19 in 2020.

Dr Bosty was also a recipient of the Ministry of Health grant for his medical training in the United Kingdom, Scotland. He returned to Singapore to practice in 2016.
