It took one rotation in the ER of a major Boston hospital for this former med student to realize that a disproportionate number of people who came to the ER based on flawed, online self-diagnosis while patients who needed to be in the hospital often stayed at home. Recognizing this troubling dynamic, Andrew Le took a sabbatical from med school to launch Buoy Health, an AI-powered digital assistant that helps patients accurately self-diagnose and access appropriate care. The company has helped over 9 million people understand their symptoms and seek relevant care options whether it’s telemedicine, primary care, behavioral health resources, etc. Boston TechWatch caught up with Cofounder and CEO Andrew Le, MD to learn more about the company, its future plans, the impressive traction during the pandemic, and recent round of funding from investors that include Cigna Ventures, Humana, Optum Ventures, WR Hambrecht + Co, and Trustbridge Partners.
