Earlier this year the startup Doctronic launched a provocative, first-in-the-nation experiment to renew drug prescriptions with a chatbot. Now it’s refilling its coffers with $40 million in fresh funding.

Doctronic on Monday announced the Series B investment round led by Abstract and Lightspeed Venture Partners. It has now raised $65 million across three funding rounds in less than a year. The company’s core service uses a chatbot to talk to patients about symptoms and health concerns before transferring them to a clinician over telehealth for diagnosis and treatment, for a $39 fee.  

Doctronic, which describes itself as the world’s most popular AI doctor, plans to use the funding to expand hiring to keep up with growth that has progressed at a breakneck pace. The company was founded in 2023 and only started offering a service with human clinicians in January 2025. Now it’s on track to earn more than $10 million in revenue this year and is preparing to launch versions of its technology with partners, including digital health companies, health systems, and payers.
