Silicon Valley VC firm closes US$460m fund to ‘fuel’ digital health innovation
Define Ventures’ investment strategy focuses on partnering with healthcare start-ups serving multiple ecosystem partners

Define Ventures, a Silicon Valley venture capital firm that focuses on early-stage digital health start-ups, has closed a US$460m fund to advance innovation in healthcare.
Investing in incubation, seed, series A and series B stage start-ups, Define Ventures’ newest fundraise will push its total assets under management to approximately US$800m, making it one of the largest early-stage venture firms focused on investing in digital health.
“The healthcare system is evolving rapidly as multiple healthcare, technology and consumer trends converge, and even with the progress over the last few years, it remains a US$4tr market opportunity that desperately needs greater digital transformation,” says Lynne Chou O’Keefe, founder and managing partner at Define Ventures.
“At Define Ventures, we are at the centre of that convergence and combine the best of Silicon Valley thinking and deep healthcare operating experience to better understand how enterprise and consumer models will intersect to become the future of healthcare.
“We are honoured to have the support of strategic and limited partners for Fund III and Opportunities Fund who helped us raise one of the largest early-stage, digital health funds.
“We look forward to continuing to build with entrepreneurs that are redefining the healthcare ecosystem.”
Define Ventures currently partners with 21 companies and aims to attract new start-ups through “deep partnerships”.
Dan Brillman, co-founder and CEO of Unite Us, a Define Ventures partner company, says: “In the early stages of our company, Define Ventures stood out to us as a partner because its team has an established network from all corners of the healthcare ecosystem from providers to payers.
“Having Define’s experience in helping companies scale across multiple categories from enterprise to consumer models was invaluable, and we look forward to continuing to partner with Define as we expand our impact on people’s health in the community.”
Define Ventures’ investment strategy focuses on partnering with start-ups that are serving multiple ecosystem partners, such as consumers, payers, providers, employers and life-sciences companies.
The firm’s two new funds include Fund III, which will support new early-stage investments, and Opportunities Fund, which will support its existing partner companies in their growth trajectories.
