Pascal
Pascal is a Cambridge, Massachusetts climate-tech company commercializing solid refrigerants to replace the greenhouse-gas coolants that make air conditioners, heat pumps, and refrigerators bad for the climate. Spun out of Harvard in 2023, Pascal builds cooling systems around barocaloric materials - wax-like layered solids that absorb and release heat when squeezed and released - working at pressures low enough to run on today's mass-market HVAC hardware. The company raised an $8M seed round in 2024 and aims to eliminate refrigerant emissions while cutting cost and boosting efficiency.
Prefix
Prefix is a New York-based facility management platform for multi-site restaurant and retail operators. It acts as the connective layer between brands and local service technicians - coordinating on-demand and preventive repairs across HVAC, refrigeration, plumbing and electrical, and managing the full job lifecycle from request to invoice. With AI-powered vendor management and 24/7 support, Prefix says it delivers roughly 3x efficiency gains and 15%+ cost savings for the nearly 2,000 locations it serves.
Axiom Cloud
Axiom Cloud builds AI software that makes commercial refrigeration systems cheaper to run, easier to maintain, and dramatically less polluting. Its cloud platform plugs into existing refrigeration controllers at grocery stores and cold-storage facilities to spot refrigerant leaks early, shift energy use off-peak, and automate work orders - cutting both costs and the climate impact of supermarket cooling.
GlacierGrid
GlacierGrid (formerly Therma) is a San Francisco climate-tech company whose AI-powered Cooling Intelligence Platform combines IoT sensors, machine learning, and equipment controls to cut energy use, prevent food waste, and reduce carbon emissions across HVAC and refrigeration systems. Its customers include McDonald's, 7-Eleven, Marriott, Domino's, Dutch Bros, Taco Bell, Wendy's, Dunkin', Vail Resorts, and Cornell University.
