For decades we’ve heard that diabetes prevention is simple—lose weight, eat less, and exercise more. But something is wrong with this conventional wisdom.

Nearly 115 million people live with either diabetes or prediabetes in the United States, and that number is growing. It is time to reverse this trend.

Virta was founded in 2014 with the goal of reversing type 2 diabetes in 100 million people by 2025. Our mission is inspired by our founding story, and continues to guide us today.


A Personal Beginning

Virta co-founder and CEO Sami Inkinen wins his age group at the Ironman 70.3 World Championships and finds out he has pre-diabetes that same year.

Unsatisfied with the conventional wisdom of “exercise more and eat less,” Sami digs into the science of type 2 diabetes, leading him to Drs. Stephen Phinney and Jeff Volek, renowned experts on the science of carbohydrate restriction and metabolic health.

Virta is Born

With consultation from Steve and Jeff on using nutritional ketosis for athletic performance, Sami and his wife Meredith complete a record-breaking row from San Francisco to Hawaii to bring awareness to nutrition’s impact on our health.

Sami, Steve, and Jeff join forces, combining Steve and Jeff’s scientific knowledge with Sami’s technology expertise and Virta Health is born. Our mission—to reverse type 2 diabetes in 100M people by 2025.


A Commitment to Science and Evidence

Virta’s clinical trial is kicked-off in West Lafayette, Indiana, establishing the scientific foundation for type 2 diabetes reversal and Virta’s unwavering commitment to being evidence-based.

Virta later launches publicly to coincide with the release of our first peer-reviewed manuscript, which demonstrated diabetes reversal in nearly half of our population in as little as 10-weeks. 87% of patients on insulin either reduced usage or eliminated it altogether.

Team Building and Care Model Innovation

Virta establishes an advisory board of eminent physicians, scientists, and policy makers. Dr. Don Berwick, former Administrator of the Centers for Medicare and Medicaid Services, joins Virta’s Board of Directors.

Meanwhile, we refine our continuous remote care model, upending traditional diabetes treatment by providing near real-time and technology-enabled access to physicians and health coaches. The Virta Treatment is expanded to every state in the nation.

Sustainable Type 2 Reversal and Cardiovascular Benefits

Virta’s 1-year peer-reviewed results show diabetes reversal in 60% of completing patients, with 94% of participants reducing or eliminating insulin usage.

We release another peer-reviewed paper on the cardiovascular benefits of the Virta Treatment, which showed significant improvement in 22 of 26 markers of cardiovascular disease risk in patients with T2D.

Performance-based Fees and Growth

On the heels of a $45M Series B funding, doubling our team size, and 3x growth in customers, Virta announces that we’ll put 100% of our fees at risk for our enterprise partners, accelerating adoption of the Virta Treatment and bringing diabetes reversal to as many people as possible.

So much of our story is still untold, and we’re looking forward to the journey on our way to reversing type 2 diabetes in 100 million people by 2025.
