Glucose biosensing company DexCom and ŌURA, a developer of smart ring technology, have announced a partnership to improve metabolic health.

This collaboration will integrate DexCom’s glucose data with the biometrics collected by ŌURA’s ring like vital signs, sleep, stress, heart health, and activity data. It will offer users of both products a more complete view of their overall health.

Additionally, DexCom is investing $75m in ŌURA’s Series D funding round. Finland-based ŌURA’s valuation has now exceeded $5bn.

Dexcom strategy and corporate development executive vice president Matt Dolan said: “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.

“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.”

Both partners will launch integrations to connect their products, including DexCom glucose biosensors, DexCom apps, Oura Ring, and the Oura App. These integrations will allow shared users to track glucose levels and understand how behaviours and biology impact metabolic health.

The companies will also co-market and cross-sell each other’s products. The first app integration is expected to launch in the first half of 2025.

ŌURA CEO Tom Hale said: “This partnership with Dexcom will enable us to empower our members to make informed decisions and adjust behaviours 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.”

Recently, DexCom launched Stelo, which is said to be the first glucose biosensor in the US cleared for use without a prescription.

ŌURA is said to have sold 2.5 million rings and expects annual sales to double in 2024 to around $500m.

The smart ring maker also introduced a new feature, Meals, within Oura Labs, an opt-in innovation hub. This feature tracks meal timing and aligns it with users’ daily routines. Last month, the company agreed to acquire Sparta Science, an enterprise software company, for an undisclosed amount. In early October, ŌURA introduced its fourth-generation hardware product, Oura Ring 4.
