ColdVentures’ ColdVest Gets Hot in Seed Round

ColdVentures, a developer of a body cooling medical device, has closed its seed funding round at a $2.5 million post-money valuation.

The Los Angeles-based startup, founded in 2023, is focused on preventing heat-related illnesses by bringing its FDA Class 1-certified wearable cooling solution to environments facing rising heat stress risks.

ColdVentures manufactures ColdVest, a patented, single-use FDA Class 1 medical device designed for rapid core body cooling through a self-contained chemical reaction that does not require electricity or ice. To activate the device, three liters of water are added to its integrated bladder, triggering the cooling chemicals and allowing the vest to be placed over the torso for immediate cooling effects.

The product provides immediate temperature relief for individuals experiencing heat-related stress or illness and can reduce core body temperature by up to 10 degrees Fahrenheit in well under 30 minutes.

ColdVest is used in schools, athletic programs, indoor industrial environments, and outdoor job sites such as construction zones—areas where heat exposure can present serious health risks. The device is positioned as a portable, non-invasive cooling solution aimed at preventing heat-related injuries or fatalities, particularly as climate conditions intensify globally.

ColdVentures, led by CEO Tracie Wagman, was founded in 2023 and is headquartered in Los Angeles.

“As global temperatures rise, the need for effective, portable cooling solutions becomes increasingly critical,” said Ms. Wagman. “Our mission is to provide accessible tools to prevent heat-related health issues, and this funding will enable us to scale our operations and reach more communities in need.”

The ColdVest product is currently available in the United States, Japan, and Australia.
