Smart ring maker raised $900M Series E at $11B valuation in Oct 2025; projects $1B+ revenue in 2025 and $1.5B in 2026; 5.5M rings shipped; 80% hardware and 20% subscription revenue mix; dominates wrist-free health tracking for sleep and recovery.
Oura is a Finnish health technology company best known for its smart ring — a wearable that tracks sleep, heart rate variability, body temperature, and readiness scores. Founded in 2013 and headquartered in San Francisco with R&D roots in Oulu, Finland, the company has shipped over 5.5 million rings globally since 2015, with nearly 3 million sold in 2025 alone.\n\nIn October 2025, Oura closed a $900M Series E led by Fidelity Management & Research, with participation from Iconiq, Whale Rock, and Atreides, pushing its valuation to approximately $11 billion — more than double its prior $5.2B round. The company reported over $500 million in revenue in 2024 and projected sales to exceed $1 billion in 2025, with a $1.5 billion forecast for 2026. Revenue is roughly 80% hardware and 20% monthly subscriptions at $6 per member.\n\nOura has built a strong enterprise and healthcare channel, partnering with the NBA, NFL, and major health systems to position the ring as a clinical-grade passive monitoring device. The subscription layer, with 2 million paying members, underpins a high-retention, recurring-revenue model that differentiates it from commoditized fitness trackers.
Apple Watch, $18B+ revenue 2024, 22% global smartwatch market share, 34% US wearables market, 100M+ active users, Series 10 (2024): sleep apnea detection, blood oxygen, ECG, fall detection, watchOS 11, fitness tracking leader
Apple Watch was introduced in 2015 as Apple's entry into personal computing worn on the wrist, designed to extend the iPhone experience to the body and provide health and fitness intelligence unavailable from any other consumer device. Apple's mission for the product evolved rapidly from notification delivery to health monitoring, driven by the recognition that continuous, passive measurement of physiological signals could provide clinically meaningful insights at population scale. Its core technology integrates custom Apple silicon, optical heart rate sensors, an electrical heart sensor for ECG, a blood oxygen sensor, and accelerometers within an ultra-compact, water-resistant enclosure running watchOS.\n\nApple Watch Series 10 (2024) introduced sleep apnea detection — a first for any consumer wearable — joining an existing health feature set that includes ECG, irregular heart rhythm notifications, blood oxygen monitoring, crash detection, and fall detection. The Apple Watch platform connects tightly with the Health app and iPhone ecosystem, with third-party app integrations across fitness, medication tracking, mental health, and chronic disease management. Apple Watch serves a broad customer base from fitness-focused consumers to patients with prescribed monitoring needs, supported by FDA clearances on its core health features.\n\nApple Watch generated an estimated $18 billion or more in revenue in 2024, capturing approximately 22% of global smartwatch market share and 34% of the US wearables market, with more than 100 million active users globally. It competes with Samsung Galaxy Watch and Garmin but has no peer in terms of health feature depth, ecosystem integration, and installed base. As regulatory bodies and health systems increasingly recognize wearable-derived data as clinically actionable, Apple Watch's combination of consumer scale and health credibility positions it as the de facto platform for digital health at the consumer level.
