Drew Baglino Launches Innovative Heat Pump Startup Sadi Thermal Machines

TL;DR

• Former Tesla executive Drew Baglino has launched Sadi Thermal Machines, a heat pump startup based in Scotts Valley, California, marking his second venture since leaving Tesla in 2024.
• The company, named after thermodynamics pioneer Sadi Carnot, employs Tesla alumni and builds on Baglino's expertise in heat pump tech, including the Model Y's "octovalve" system.
• Sadi targets energy efficiency and sustainability, potentially extending Tesla's innovations from EVs to residential and commercial applications amid rising demand for green heating solutions.

From Tesla Powerhouse to Serial Entrepreneur

Drew Baglino, once a key architect of Tesla's powertrain and energy innovations, has quietly stepped back into the spotlight as an entrepreneur. After departing Tesla in April 2024 amid a wave of layoffs, Baglino didn't stay idle for long. His first post-Tesla venture, Heron Power, emerged in 2025, focusing on solid-state transformers to modernize the electric grid. Now, less than a year later, he's founded Sadi Thermal Machines—a stealthy startup poised to disrupt the heat pump market. Registered in June 2025 in Delaware and California, Sadi shares headquarters with Heron Power in Scotts Valley, California, signaling Baglino's ambitious push into complementary clean energy technologies.

The Man Behind the Machines

Baglino's Tesla tenure was nothing short of legendary. As Senior Vice President of Powertrain and Energy, he held patents on groundbreaking heat pump technology that powered the efficient thermal management in vehicles like the Model Y. His "octovalve" system—a compact, multi-path valve—optimized heating and cooling, slashing energy waste in electric vehicles. In a 2022 discussion with Elon Musk, Baglino floated the idea of adapting this tech for homes and businesses, hinting at the vision now materializing with Sadi. Post-Tesla, he's assembled a dream team of former Tesla engineers, as evidenced by LinkedIn profiles, blending proven expertise with fresh entrepreneurial drive.

Heat Pumps: The Unsung Heroes of Sustainability

At the heart of Sadi Thermal Machines is the heat pump—a deceptively simple device that's revolutionizing energy efficiency. Unlike traditional heaters that burn fuel to generate warmth, heat pumps transfer heat from outside air (even in cold climates) into buildings, using electricity far more efficiently. Modern advancements, like those Baglino pioneered, achieve coefficients of performance (COP) exceeding 4—meaning they deliver four units of heat for every unit of electricity consumed. This slashes carbon emissions and energy bills, making heat pumps pivotal in the global push for net-zero buildings. With governments incentivizing adoption through rebates and mandates, the market is exploding: U.S. installations surged 40% in 2025 alone, per industry reports.

Sadi's Potential Game-Changer

Details on Sadi remain scarce, true to its low-profile launch, but the clues point to high-impact innovation. Named after Nicolas Léonard Sadi Carnot, the 19th-century physicist dubbed the "father of thermodynamics," the company evokes precision engineering rooted in fundamental science. Baglino's track record suggests Sadi could deliver next-gen heat pumps with Tesla-level integration—perhaps ultra-compact designs, AI-optimized controls, or seamless ties to grid tech from Heron Power. As electrification accelerates, Sadi arrives at a inflection point: residential heat pumps could cut U.S. heating emissions by 60% by 2030, while commercial applications promise massive scalability for data centers and factories.

Broader Implications for Clean Energy

Baglino's dual startups underscore a Tesla diaspora fueling the energy transition. Heron Power's $30-50 million Series A hunt, led by Capricorn Investment Group, highlights investor appetite for grid upgrades. Sadi extends this to end-use efficiency, potentially creating synergies: imagine heat pumps dynamically balancing loads with solid-state transformers. For consumers and the planet, it's a win—lower costs, reduced fossil fuel dependence, and accelerated decarbonization. As Baglino makes good on his vision, Sadi Thermal Machines could redefine how we heat our world, proving that one executive's exit from Tesla is the broader ecosystem's gain. Watch this space: more revelations are likely as Sadi heats up.
