Aeroseal Raises $22M in Series A Funding

Aeroseal, LLC, a Dayton, Ohio-based climate tech company lowering carbon emissions from residential and commercial buildings, raised $22m in Series A funding.

The round was led by Breakthrough Energy Ventures with participation from Energy Impact Partners and Building Ventures.

The company intends to use the funds to scale its R&D, marketing team, and increase support of its dealer network.

Led by Amit Gupta, CEO, Aeroseal has developed technologies, HomeSeal Connect and AeroBarrier Connect, which inject a fog of sealant particles into pressurized spaces. These particles safely seal leaks as big as 5/8” and as small as a human hair. Software tracks the entire process, creating a certificate of completion showing before and after leakage.

The company has 100 employees in Dayton, Ohio, and serves contractors and builders who are sealing ducts and walls around the globe in everything from homes, hospitals, and schools to government facilities, hotels, and offices.
