"Sadi was formed in June 2025 and shares its Scotts Valley, California, headquarters with Heron Power, a startup also founded by Baglino, that sells solid-state transformers, according to company filings. The name of the company is an apparent reference to Nicolas Léonard Sadi Carnot, a pioneering French physicist whose work formed the foundation of modern thermodynamics, including the internal combustion engine and the heat pump. Little is known about Sadi Thermal Machines, however, it appears to employ several Tesla alumni, according to a review of LinkedIn and a source familiar with the startup."
"Before founding Heron Power and Sadi Thermal Machines, Baglino spent nearly two decades at Tesla, where he worked on everything from the original Roadster to the Powerwall and Powerpack energy storage systems. When Baglino left Tesla in April 2024, he had risen to senior vice president, overseeing the development of the company's core energy technologies, including electric motors, batteries, and power electronics."
"Along the way, Baglino worked on Tesla's heat pumps. He's cited as an inventor on a patent for a thermal management system that operates two coolant loops, one to cool the battery and another to cool drivetrain components. To manage the two loops, Baglino and his teammates developed three-way and four-way valves that give an EV's thermal management system more sophisticated control over the temperature of various components."
Drew Baglino has founded Sadi Thermal Machines, a heat pump startup formed in June 2025 in Scotts Valley, California. The company shares headquarters with Heron Power, another startup Baglino founded that sells solid-state transformers. The name Sadi appears to reference Nicolas Léonard Sadi Carnot, associated with foundational work in thermodynamics, including heat pumps. Little public information is available about Sadi Thermal Machines, but it appears to employ multiple Tesla alumni. Baglino previously spent nearly two decades at Tesla, rising to senior vice president overseeing core energy technologies. He worked on Tesla heat pumps and is listed as an inventor on a patent for a thermal management system using two coolant loops and valves for more sophisticated temperature control.
