Dorothea Koh

Dorothea Koh, co-founder and CEO of Bot MD - an AI platform that puts a medical assistant in every doctor’s pocket.

Born and raised in Singapore, Dorothea studied Biomedical Engineering and Economics at Northwestern University. Her early career took her across hospitals in India, China, and the Philippines, where she watched exhausted doctors juggle outdated systems just to find a single answer.

In 2018, she decided to change that.

▪ Dorothea founded Bot MD, a phone-based AI assistant that lets doctors pull up clinical protocols, drug information, schedules, and hospital systems in seconds.
▪ What started with just 20 clinicians at the National University of Singapore Hospital quickly spread across Asia as word got out.
▪ When the pandemic hit, Dorothea’s team expanded Bot MD to help monitor the vital signs of migrant workers isolated in dormitories.
▪ Doctors received real-time alerts; patients got faster care; hospitals stayed afloat during the most overwhelming months of COVID-19.

Bot MD now operates across Southeast Asia - including Indonesia, where it partners with Siloam Hospitals and the Indonesian Medical Association - and supports doctors in multiple languages, including Bahasa Indonesia.

Today, it serves more than 20,000 clinicians and has impacted over 100,000 patients.

Dorothea Koh won the 2024 Her World Hello Possibilities Award for using technology to improve lives. She was also named among the “Great Women of Our Time 2022” by The Singapore Women's Weekly. Bot MD is listed by World Health Organization as an example of health-tech innovation for impact.

It’s inspiring to see women like Dorothea use technology to solve real problems and bring dignity, speed, and care back to frontline healthcare.
