Aeroseal Raises $67M in Series B Funding 


Aeroseal, a Miamisburg, OH-based climate-tech startup, raised $67M in Series B funding.

The round was led by Breakthrough Energy Ventures and Climate Investment, with participation from Beazer Homes and Aramco Ventures, and existing partners Building Ventures, 2150, and Energy Impact Partners.

The company intends to use the funds to expand operations and its business reach.

Led by CEO Amit Gupta, Aeroseal offers a patented solution to the pervasive issue of energy leaks in buildings. The company provides carbon dioxide removal technology that produces a gum that seals air ducts and building envelopes efficiently. The application requires no lifestyle change for building tenants, no building renovation, and can be done in a single afternoon. Its patented methods are one of the ways to reduce energy loss from buildings and improve HVAC system performance.

Aeroseal has over 200 employees in Dayton, Ohio, who serve contractors, builders, and building owners by sealing ducts and walls in their homes and properties.  The company has already achieved remarkable milestones, having sealed over 260,000 homes and thousands of commercial buildings across 30 countries.
