Wellness technology is evolving, and Chillshark is leading a new wave by bringing cold plunge therapy into the home. Founded in January 2024 by Keegan O’Connor, this Austin-based startup has developed a compact, efficient system that transforms any standard bathtub into a cold plunge—without the need for expensive, space-consuming equipment.
The Chillshark Difference

Cold plunge therapy is no longer just for elite athletes and high-end recovery centers. Chillshark offers a practical solution that seamlessly integrates with your home setup.
Key features of the system include: ✅ A high-performance chiller that maintains consistent, ice-cold temperatures. ✅ A circulation system ensuring an even and refreshing cold plunge experience. ✅ Smart controls for scheduling and remote operation, so it’s ready when you are. ✅ Advanced filtration with a 10-micron water filter for hassle-free maintenance.
By simplifying access to cold therapy, Chillshark aims to help users improve muscle recovery, reduce inflammation, and enhance mental clarity—all from the comfort of home.
From Personal Experience to Innovation
For founder and CEO Keegan O’Connor, Chillshark is more than just a business. His personal journey with PTSD led him to discover the therapeutic benefits of cold-water immersion. Recognizing its potential, he set out to develop an at-home solution that could make a difference for others as well.
The company has since partnered with Grey Team, a nonprofit dedicated to supporting veterans, to study how cold plunges can aid in PTSD treatment. This collaboration highlights Chillshark’s commitment to not just fitness and recovery, but also mental health research.

Chillshark has successfully secured $600,000 in funding, including a $500,000 equity raise in September 2024. The company is currently offering early access through a Kickstarter campaign, allowing backers to secure their units at an exclusive discount.
