About Chillshark
Innovating to bring the benefits of cold water immersion to everyone
Our Mission
At Chillshark, our mission is to make the transformative benefits of cold plunge therapy accessible to everyone, empowering individuals to unlock peak physical performance, emotional resilience, and mental clarity. We believe in the profound impact of cold exposure—whether it's for enhancing recovery, managing stress, or supporting mental health challenges like PTSD.
Meet the Founder Keegan O'Connor
Keegan O'Connor is the Co-Founder and CEO of Chillshark, a recovery technology company building the world's first intelligent cold water immersion platform. His path to founding Chillshark began with a deeply personal connection to recovery — after his own experience navigating PTSD treatment, he discovered cold water immersion as the single intervention that reliably regulated his nervous system, and set out to bring that access to others through science-backed technology.
