Quilt Raises $20M Series B to Expand Smart Heat Pump Systems and Accelerate Home Electrification
Quilt, a Redwood City, California–based clean home climate technology company, has significantly expanded its funding to scale production and sales of its intelligent heat pump systems designed to reduce carbon emissions from residential heating and cooling. The startup recently announced a $20 million Series B funding round, bringing its total capital raised to approximately $64 million, building on earlier investments to accelerate its mission of electrifying home climate systems with smarter, more efficient technology.
The Series B financing was led by Energy Impact Partners and Galvanize Climate Solutions, two prominent climate‑focused investment firms that have supported Quilt’s growth through multiple funding rounds. Additional participation in the Series B came from investors including Alumni Ventures, Gradient Ventures, Incite Ventures, and Lowercarbon Capital, reflecting ongoing confidence from both existing and new backers in Quilt’s technology and strategic direction as it expands its market footprint. Veery Maxwell of Galvanize Climate and former Nest CFO Tom vonReichbauer also joined Quilt’s board of directors as part of the financing package.
Quilt’s funding journey began with earlier support to develop and launch its product. In April 2024, the company secured $33 million in Series A funding, co‑led by Energy Impact Partners and Galvanize Climate Solutions, with participation from Lowercarbon Capital, Gradient Ventures, MCJ Collective, Garage Capital, Incite Ventures, and investor-entrepreneur Drew Scott, widely known as HGTV’s Property Brother. That capital was aimed at fueling Quilt’s initial product launch and expansion into new markets across the United States.
Prior to the Series A, Quilt closed a $9 million seed round that helped finance the development of its smart heat pump technology and early operational scaling. That initial funding allowed the startup to refine its integrated system of sleek hardware and intelligent software controls that enable homeowners to monitor and optimize heating and cooling room‑by‑room for comfort and energy efficiency.
Founded with the mission of moving residential climate control off fossil fuels, Quilt designs home climate systems that blend advanced ductless heat pump hardware with intuitive software, occupancy awareness, predictive energy usage, and a mobile app to deliver efficient and comfortable heating and cooling. By enabling all‑electric temperature management tailored to individual rooms, Quilt’s systems aim to reduce energy consumption and lower utility bills while offering a modern user experience that appeals to consumers seeking sustainable alternatives to traditional furnaces and air conditioners.
The recent Series B funding will support Quilt’s continued geographic expansion, product innovation, and partner network growth. The company has already installed nearly 1,000 heat pump units across 16 U.S. states and five Canadian provinces and plans to accelerate deployments as demand for electrified home climate solutions increases amid stronger climate policies and consumer interest in energy efficiency. The additional capital will help shorten customer wait times, expand service areas, enhance product features, and deepen support for Quilt’s network of certified installation partners.
Quilt’s approach to climate‑friendly HVAC technology distinguishes itself by prioritizing software‑driven control and design aesthetics alongside energy performance. Its systems have earned high efficiency ratings and deliver features such as over‑the‑air software updates that improve performance over time, real‑time energy usage insights, and automation that adjusts temperature based on occupancy patterns. These capabilities aim to reduce operational costs for homeowners while contributing to broader electrification of residential energy loads—a major focus in efforts to reduce greenhouse gas emissions tied to heating fuel combustion.
Investor enthusiasm for Quilt reflects broader trends in climate tech and sustainable home solutions, where venture capital continues to flow toward companies that combine hardware innovation with software‑enabled efficiency gains. With its enhanced funding base, Quilt is better positioned to compete with established HVAC manufacturers by offering homeowners a compelling, energy‑efficient alternative that aligns with growing environmental priorities. The company’s leadership anticipates that continued product improvements and expanded market reach will further drive adoption of electrified heat pump systems and support decarbonization efforts at the residential level.
As Quilt moves forward with its Series B‑backed initiatives, the company is expected to deepen its impact on the home climate control market, making sustainable heating and cooling technologies more accessible to a broader audience while reinforcing investor confidence in the clean energy transition.
