California-based diabetes management company Dexcom is combining data from its glucose monitor with vital sign, sleep, stress, heart health and activity data from the Oura Ring.

Dexcom is also investing $75m in Ōura as part of a partnership the companies hope will help millions of people improve their metabolic health.

Combining Dexcom glucose data with the biometrics collected by Oura Ring should provide users of both products with a more complete picture of overall health. The $75m investment in Ōura’s series D funding brings Ōura’s valuation to more than $5bn.

“Dexcom offers the most accurate glucose biosensing systems on the market that help reveal the impact of daily lifestyle choices on glucose levels and enable our users to make informed decisions about their health and overall well-being,” said Matt Dolan, executive vice president at Dexcom. “Partnering with Ōura gives us the opportunity to redefine the category again, integrating data from Dexcom glucose biosensors with the continuous insights and metrics measured by Oura Ring. This powerful combination will attract new shared customers who want to better understand the link between activity, sleep, nutrition and their glucose.”

With this partnership, Dexcom and Ōura plan to launch integrations enabling data to flow between their products, including Dexcom glucose biosensors, Dexcom apps, Oura Ring and the Oura app, so shared users can track their glucose levels and understand the impact of behaviour and biology on their metabolic health. The companies will also co-market and cross-sell each other’s products. The first app integration resulting from the partnership is expected to launch in the first half of 2025.

“Ninety-seven percent of Oura members have expressed interest in understanding how the food they eat impacts their health,” said Tom Hale, Ōura chief executive officer. “This partnership with Dexcom will enable us to empower our members to make informed decisions and adjust behaviour to positively impact their biometrics and long-term health. Working together, Ōura and Dexcom will help members decide what and when to eat by surfacing correlations between activities like sleep and exercise and members’ glucose levels. And, because we know that people are affected differently by the same foods and activities, guidance and insights will be personalised.”

Dexcom has been the pioneer in glucose biosensing for 25 years, with a long list of first-in-market innovations. Most recently, Dexcom led the creation of a new category by launching Stelo, a glucose biosensor cleared for use without a prescription in the USA. More than 2.5 million active users across the globe use Dexcom’s portfolio of glucose biosensors to take control of their health.

This year has marked a significant acceleration of Ōura’s business, including its metabolic health roadmap. Earlier this year, Finland-based Ōura announced it has sold 2.5 million rings. It, expects to see annual sales double in 2024 to roughly $500m and it is profitable.

Ōura also introduced this year a new feature, Meals, to the Oura Labs opt-in innovation hub within the Oura app that allows members to test features in development and provide feedback. The feature enables tracking meal timing and then maps that timing to their chronotype to understand how, what and when people eat can impact health metrics such as sleep, stress and recovery.

Eighty-eight percent of Americans are not in optimal metabolic health, which comes with increased risk of developing co-morbid conditions such as diabetes, heart disease, stroke or all three. Partnerships that combine medical-grade technology with software are driving forward the consumerisation of healthcare, allowing consumers to drive their health journeys and empowering them with their own health information. Dexcom and Ōura plan to meet a need that will change the healthcare landscape going forward.

Dexcom (Dexcom.com) empowers people to take control of health through biosensing technology. Founded in 1999, Dexcom has pioneered and set the standard in glucose biosensing for more than 25 years.

Founded in Finland in 2013, Ōura (ouraring.com) has offices in Oulu, Helsinki, San Francisco and San Diego.
