What Quilt does

Quilt Systems, Inc. is a Redwood City, California-based climate technology company founded in 2022 by Paul Lambert (CEO), Matthew Knoll (CTO), and Bill Kee (COO) that designs and sells ductless heat pump systems with integrated smart controls for residential homeowners. The company's product ecosystem comprises wall-mounted indoor units, outdoor compressor units available in 2-zone and 3-zone configurations, the Quilt Dial thermostat, the Quilt Sense radar-and-compute sensing module, and mobile applications for both consumers and HVAC technicians. Manufacturing is distributed across Vietnam, China, and Malaysia through joint development agreements, while hardware and software design is led by Quilt's California-based engineering team, which draws alumni from Google, Apple, Nest, Google X, and Rethink Robotics.

The company's technical proposition centers on industry-leading 25+ SEER2 efficiency ratings (AHRI certified), cold-weather performance (90% of rated capacity at -13°F), and a "software-defined HVAC" architecture demonstrated by the first over-the-air performance update in the HVAC industry, which delivered a 20%+ capacity boost without hardware changes. The system leverages radar-based occupancy sensing, room-by-room zoning, and a growing data flywheel built on roughly 1,000 installed units to optimize compressor control and energy savings. Secondary use cases include boutique hotels (The Madrona, Hotel Lilien) and short-term rental properties, with custom-finished indoor covers designed to blend into interior aesthetics.

Quilt operates an asset-light distribution model: all installations are handled exclusively by a network of 100+ Certified HVAC Partner installers across 26 US states and 6 Canadian provinces, supported by the Toolbox technician app. Revenue comes primarily from hardware sales with customized system pricing (upfront costs typically exceeding $15,000 for full-home installations), supplemented since May 2026 by the Palmetto Comfort Plan — a monthly lease starting at $117 per room covering equipment, installation, maintenance, and warranty — that converts the upfront cost barrier into recurring revenue. The company has raised $64 million in total venture funding across seed, Series A ($33M, April 2024), and Series B ($20M, December 2025) rounds from investors including Energy Impact Partners, Galvanize, Sequoia Capital, Gradient Ventures, and Lowercarbon Capital.
