Orion Raises $17.5M to Reimagine Sleep with AI-Powered Smart Mattress Covers

Orion, the sleep-technology startup founded by Harry Gestetner, his father Daniel Gestetner, and partners Blake Johnson and Scott Cohen, has raised $17.5 million in a seed round to accelerate its mission of reinventing how the world sleeps. The round was led by Mucker Capital, with participation from Browder Capital, Second Sight Ventures, and an elite roster of operators, founders, and industry heavyweights across tech, consumer, and wellness.

Orion’s flagship product is a sensor-activated, AI-powered mattress cover that dynamically regulates body temperature throughout the night — cooling or warming as needed to help users reach deeper, more restorative sleep. Paired with real-time biometric analysis and a subscription-driven insights platform, Orion aims to make elite sleep accessible at scale. The funding will fuel product development, expand R&D, and grow Orion’s recurring subscription model for personalized sleep intelligence.

Why It’s a Game-Changer

Sleep is the single most important lever for recovery, longevity, hormone balance, and cognitive performance — yet most “sleep products” are static. Orion is building dynamic sleep.

• Temperature is the key variable in achieving deep and REM sleep. Research shows that even minor overheating disrupts the body’s ability to enter restorative sleep cycles.
• Traditional mattresses trap heat. Orion’s cover actively responds to your physiology.
• The company aims to produce more affordable alternatives to traditional smart beds, democratizing access to high-quality sleep tech.
• Their subscription-based model adds another layer: ongoing biometric tracking, adaptive sleep coaching, and personalized adjustments — similar to how WHOOP and Oura transformed wearables.

Tech-enabled recovery has exploded in fitness, but sleep — the pillar everything else rests on — is the next frontier.

The Playbook Take

Orion is building what we’ve needed for years: sleep gear that works as hard as we do. We’re entering a world where recovery isn’t just about ice baths, compression boots, or protein shakes — it’s about unlocking the most powerful recovery tool we all ignore: sleep. Orion isn't selling mattresses — they’re selling sleep optimization systems. And if you care about performance, longevity, or just waking up without tossing and turning, this may be the most underrated upgrade of the decade.

If performance, longevity, and recovery are the future — sleep optimization is the arena. And Orion just put the rest of the industry on the clock.
