Lim Wai Mun was born in Singapore and studied mechanical engineering at the National University of Singapore.
In 2016 he was delivering meals to elderly people and saw that many could not reach a doctor. He planned for doctors to visit homebound seniors for free, and took a year-long unpaid sabbatical to build it. Doctors with their own caseloads were hard to mobilise.
Doctor Anywhere launched in 2017 as telehealth for everyone. Patients and parts of the industry were sceptical, so the company added physical clinics and pharmacy delivery to build trust.
In August 2021 it raised a S$88 million Series C led by Asia Partners. In December 2021 it added $38.8 million and acquired the Catalist-listed Asian Healthcare Specialists. Lim was named EY Entrepreneur of the Year Singapore in 2022, and the company raised $40.8 million in December 2023. It opened Orchard MedSuites in February 2024.
