About Lynne Chou O'Keefe

Lynne Chou O'Keefe brings unusual hands-on medical device experience from Guidant and Abbott Vascular to venture capital, having launched over ten product families before becoming a VC, which gives her a deeper understanding of product development, regulation, and commercialization than most digital health investors. She was an early board member at Livongo during its journey from startup to IPO and multibillion-dollar acquisition, and now focuses exclusively on early-stage digital health companies at Define Ventures, positioning herself as a day-zero partner who helps founders shape business models and navigate the complex intersection of consumer experiences and healthcare reimbursement systems.
