## Summary

Raised $20M Series B (Dec 2025) led by Energy Impact Partners and Galvanize Climate Solutions. ~1,000 units across 16 US states and 5 Canadian provinces. OTA software updates. Apple/Tesla/Nest design pedigree.

## Company Overview

Quilt makes premium whole-home heat pumps designed by alumni of Apple, Tesla, and Nest — applying consumer hardware product excellence to HVAC systems that have historically been designed by mechanical engineers with minimal user experience investment. The company raised $20 million in Series B financing in December 2025, led by Energy Impact Partners and Galvanize Climate Solutions, with approximately 1,000 units installed across 16 US states and 5 Canadian provinces.

Quilt's Tesla-inspired product philosophy — treating the heat pump as a software-defined hardware product — is the primary differentiator from incumbent HVAC manufacturers like Carrier and Lennox. Quilt deploys over-the-air software updates that improve heat pump performance post-installation, incorporating operating data from the installed base to continuously optimize the thermodynamic control algorithms. This creates an improving product experience over time, opposite to traditional HVAC systems that degrade without service.

The premium consumer positioning and Energy Star certification qualify Quilt installations for the Inflation Reduction Act's $2,000 heat pump tax credit, directly subsidizing adoption economics and aligning Quilt with the federal incentive structure designed to accelerate building decarbonization. Energy Impact Partners' investment connects Quilt to utility relationships that enable virtual power plant integration — aggregating Quilt heat pumps for demand response programs that provide grid services revenue.

## Frequently Asked Questions

### What does Quilt make?
Premium smart whole-home heat pumps by Apple/Tesla/Nest alumni — OTA software updates improve performance over time. ~1,000 units across 16 US states and 5 Canadian provinces.

### How much has Quilt raised?
$20M Series B in December 2025 led by Energy Impact Partners and Galvanize Climate Solutions.

### What is the OTA update advantage?
Heat pump algorithms improve with deployed data — continuous optimization over time, opposite to traditional HVAC that degrades without service. Software-defined hardware approach.

### What is the IRA connection?
Quilt installations qualify for the $2,000 IRA heat pump tax credit — directly subsidizing adoption and aligning with federal incentives for building decarbonization.

### What does Quilt's smart heat pump do differently from standard heat pumps?
Quilt's heat pump system includes an AI-powered energy management system that learns home thermal behavior and optimizes heating and cooling for comfort, cost, and grid participation — going beyond simple thermostat scheduling to dynamic optimization based on weather, electricity prices, and grid signals.

### How does Quilt participate in virtual power plant programs?
Quilt enrolls installed heat pump systems into VPP programs, using its AI to pre-heat or pre-cool homes before grid stress events and then reduce heat pump operation during peaks — providing grid flexibility without sacrificing comfort, while earning customers demand response payments.

### What is Quilt's target customer segment?
Quilt targets homeowners in California and other expensive electricity markets who want to reduce heating and cooling costs while participating in the energy transition. The combination of efficiency savings, demand response payments, and IRA heat pump rebates makes the system compelling financially.

### Does Quilt's system qualify for Inflation Reduction Act incentives?
Yes — Quilt's heat pump systems qualify for the IRA's 30% residential clean energy tax credit and potential HEEHRA rebates of up to $8,000 for qualifying households, significantly reducing the upfront cost of switching from gas heating to Quilt's all-electric system.
