In 2009, Amit Gupta, a rising executive at Carrier HVAC, inherited responsibility for Aeroseal, a neglected product line with untapped potential.
Aeroseal’s roots trace back to 1993 when Dr. Mark Modera (now a professor at UC Davis) invented a technology that used micron-sized aerosol particles to seal air leaks inside air ducts and building envelopes.
The idea was groundbreaking: fix the leaks and tackle one of the world’s most absurd inefficiencies—10% of global energy wasted due to buildings leaking air.
Here’s the math:
↳ Buildings consume 40% of global energy
↳ Half of that energy is used for heating and cooling (HVAC)—equaling 20% of all energy globally
↳ Half of that HVAC energy is wasted through leaks—equaling 10% of global energy
For Amit, this wasn’t abstract. With relatives in the UK enduring drafty homes and soaring heating bills, he saw the economic, social, and environmental stakes firsthand. Many faced the monthly dilemma: "heat or eat."
In 2010, Amit left his corporate career, rebooted Aeroseal, and focused on what customers care about most:
✅ Cutting energy bills
✅ Improving indoor air quality
✅ Creating comfortable spaces
At first, he bootstrapped the business, working with homeowners in older, leaky homes. He refined the technology, filed global patents, and grew opportunistically.
Then came the tipping point: the world’s biggest builders, cities, and investors embraced the urgency of climate action. Amit was ready. Aeroseal was ready.
Today, Aeroseal has sealed over 260,000 buildings, saving billions in energy costs, cutting thousands of tons of CO2 emissions, and improving comfort for millions.
Backed by Bill Gates’ Breakthrough Energy Ventures and other world-class climate tech investors, including Climate Investment (CI), Aramco Ventures, 2150, Energy Impact Partners, and Building Ventures, Aeroseal is now scaling to seal the cracks in our energy future.
