Tetra is leading the clean energy transformation by adding transparency and efficiency into a forgotten industry. Home improvement contractors are left in the past, lacking automation and technology to run and scale their small business. This leaves homeowners without the necessary information to make easy, fast decisions and creates a painful buying process. Homeowners are unaware they can reduce carbon emissions and lower their utility bills. We provide the most efficient and affordable options to homeowners, improve their experience, and coordinate the installation of home improvement projects. In doing so, we're “super powering” contractors by automating admin tasks and allowing them to focus on installation excellence and customer happiness. We’re starting by transforming heating and cooling replacements, a $120 billion industry which makes up 12% of total energy usage in the US. Federal and state government agencies allocate billions of dollars in incentives to help homeowners choose high-efficiency systems—now at unprecedented levels thanks to the Inflation Reduction Act of 2022—but the dollars are historically underutilized due to lack of customer awareness. We’re democratizing and unlocking those incentive dollars. We started in Massachusetts, where we’re now 4%+ of the heat pump replacement market, and launched in New York in mid-2024, where we’re already seeing great traction, validating that our model has the potential to scale nationwide. With backing from the likes of Lerer Hippeau, Gutter Capital, Greycroft, and others, we’re now preparing to do exactly that.
