ŌURA

I hold a PhD in neuroscience and have spent 13 years in sleep research. Before joining Oura, I was a postdoctoral researcher at UC Berkeley where I built an open-source algorithm that scores sleep stages from polysomnography. It was published in a top-tier journal and is now among the most widely used and cited automated sleep staging tools in the field. Since 2020, I have been the lead algorithm scientist for sleep tracking at Oura.

Oura’s business is built on turning round-the-clock signals from your body into insights you can act on, so that health becomes a daily practice instead of a guessing game. When we looked at our own support through that same lens, the gap was obvious—the experiences that mattered most were the ones we could not clearly see. To address this, we set out to find a better way to measure those experiences and developed a new metric: the Total Customer Experience Score, or TCX.

Every day, millions of members rely on Oura Ring to better understand their rest, readiness, and overall health. We’ve always provided our community clarity about how our technology works—what Oura measures, how PPG technology works, and how Oura’s algorithms perform against clinical standards like polysomnography (PSG). A recent baseless, opportunistic legal allegation seeks to discredit how consumer wearables—including Oura Ring—track and estimate sleep stages.

I have spent my career believing that innovation is the engine that expands scientific knowledge and moves us closer to improving the health and wellness of humanity.

Oura is pleased to welcome Sanjay Chandra as Chief Information Officer, reporting to Sean Brecker, and Han Chiu as Senior Vice President of AI and Software Engineering, reporting to Michael Chapp. Together, they bring deep experience scaling enterprise technology, software organizations, health technology, and AI-powered product development during periods of significant growth. “Oura has spent more than a decade earning our members’ trust with their health data and insights,” said Tom Hale.

Today, Oura announced long-term partnerships with top-10-ranked tennis players Coco Gauff and Taylor Fritz to spotlight how elite athletes are taking a holistic approach to health as they compete at the highest level of sport. Heading into the 2026 US Open, the fourth and final Grand Slam tournament of the year, Gauff and Fritz are leveraging research-grade data and insights from Oura to navigate how they prepare, compete, and recover.

Today, Oura announced it has purchased 500 Pine Street to serve as its permanent headquarters, marking a long-term investment in the company’s future and in its people. “500 Pine represents the next chapter for Oura,” said Tom Hale, CEO at Oura. “Owning our headquarters reflects our confidence in the future we’re building — as a company, as a category leader, and as a team.

In building Cycle Insights, our goal was simple: to give you a clearer window into your body’s natural rhythms. We know that for many members, Oura Ring isn’t just a sleep tracker—it’s a daily partner in understanding your fertile window, reading your body’s subtle temperature signals, and knowing when to try. Now, we’re asking for our members’ help to take that science another step forward.

From June 11 to July 19 this summer, millions of fans around the globe tuned in to support their countries in the 2026 World Cup. And while the drama unfolded on screen, Oura Ring was tracking another story right on our members’ fingers. Oura’s data science team analyzed de-identified, aggregate Oura Member data from competing countries to see how the tournament shifted real-world health metrics—from late-night bedtimes to physiological stress spikes.

At 31, Nicole was a healthy, high-achieving professional training for her first half-marathon. Suddenly, her health took a nosedive. Her Oura data recorded a drastic drop in heart rate variability (HRV), disrupted sleep, a constantly elevated resting heart rate, and high daily stress levels. What followed was a medical mystery filled with endless scans, panels, and frightening misdiagnoses—ranging from early-onset Multiple Sclerosis (MS) to rare autoimmune syndromes.
