Quilt has raised $20 million in new funding. The Redwood City startup builds modern, app-controlled heat pumps, and the Series B round closed recently. The company plans to use the investment to scale operations and compete with established HVAC manufacturers. According to Reuters, the heat pump sector continues to expand at a fast pace.
Energy Impact Partners and Galvanize led the round. Alumni Ventures and Gradient Ventures also participated. Former Nest CFO Tom vonReichbauer will join Quilt’s board.
This brings Quilt’s total known funding to more than $53 million. The company previously announced a $33 million Series A in April 2024. The new board additions add more expertise in consumer technology and smart home systems.
Quilt plans to extend its reach across North America. The company has installed nearly 1,000 units across 16 U.S. states and five Canadian provinces.
Quilt’s approach centers on software and product design. The company builds its hardware like a smart device, which allows performance enhancements even after installation.
One recent “over-the-air update” improved existing unit performance by more than 20%. This method stands out in the HVAC market because it turns a traditional appliance into an upgradable product.
The broader home-heating market is also shifting. Governments continue to promote heat pumps as part of emissions-reduction strategies. Quilt’s design targets homeowners who want both efficiency and modern aesthetics.
The latest investment reinforces Quilt’s long-term strategy. With a software-focused model and growing demand for energy-efficient heating, the company positions itself as a notable competitor in the evolving climate-tech landscape.
