David Stoffel
David Stoffel is the Chief Business Officer of RapidAI, the clinical-AI company whose stroke-imaging algorithms helped rewrite the rules of how strokes get treated. A medical doctor who chose boardrooms over bedsides, he has spent more than two decades turning ambitious medical technologies into standards of care - from the da Vinci surgical robot at Intuitive Surgical to mobile cardiac telemetry at iRhythm and point-of-care EEG at Ceribell. At RapidAI he runs the commercial engine: marketing, clinical affairs, education, customer success, corporate development, and finance.
Nate Mazonson
Nate Mazonson is the co-founder and CEO of Alara Imaging (Alara Gateway), a San Francisco health-tech startup building a secure gateway-as-a-service that moves radiology data between hospitals and the cloud in real time. A Dartmouth-trained environmental engineer turned Stanford MBA, he spent five years in venture capital at Cambridge Associates and Kleiner Perkins before co-founding the vertical-farming company Plenty in 2015 and then Alara in 2019. His through-line: take antiquated, high-stakes infrastructure - first food, now medical imaging - and rebuild it as modern, machine-learning-ready software.
Connie Lehman
Connie Lehman is a radiologist who spent three decades reading mammograms and decided the picture could tell a different story. As founder and CEO of Boston-based Clairity, she built the first FDA-authorized AI platform that reads a routine screening mammogram and estimates a woman's five-year risk of developing breast cancer, spotting tissue patterns invisible to the human eye. A Professor of Radiology at Harvard Medical School with more than 300 peer-reviewed publications, she left a celebrated academic career to commercialize the idea that imaging should predict cancer, not just find it. TIME named her to its 2026 TIME100 Health list and Forbes to its 50 Over 50: Innovation list.
Mohamed Shoura
Mohamed Shoura is the founder and CEO of PaxeraHealth, a Boston-based medical imaging AI company he launched in 2009 after spending 12 years inside Siemens and Toshiba Medical Systems. He holds a Ph.D. in Medical Imaging, has served as an adjunct professor at the Johns Hopkins University School of Medicine, and pursued a business degree at Harvard. Under his leadership PaxeraHealth has reached more than 2,500 PACS installations across 50+ countries, won Best in KLAS for Global PACS three years running, and closed a Series A round in late 2022. He also founded CarePassport, an award-winning patient engagement platform.
Doktor Gurson
