Thomas Kelly graduated from medical school in 2017 and began practicing medicine in Australia. However, he quickly experienced significant burnout from the healthcare system's demands.

Doctors typically see around 100 patients daily with only 10 minutes per appointment, while managing extensive administrative tasks. Inspired by his own struggles, Kelly developed Heidi, an AI tool that transcribes medical visits and generates clinical notes automatically.

His entrepreneurial journey began earlier with Oscar, an interview preparation tool for medical students that gained 20,000 users by 2020. Heidi's innovative approach has transformed medical documentation, allowing physicians to focus more on patient care. In October, the company secured $65 million in Series B funding, reaching a valuation of $465 million.

Kelly's solution directly addresses the systemic challenges healthcare professionals face daily.
