Hearth is the AI growth system for local home improvement small businesses. We build revenue-critical software for home improvement contractors — the roofers, HVAC techs, and builders who keep America running.

Our platform helps real business owners win more jobs, protect profit margins, and manage homeowner relationships professionally so they can build generational companies for their families and communities.

We are now building the next layer: a personal AI employee for every small business in the trades focused on autonomously generating sales for America’s home improvement pros. An assistant who answers every call 24/7, qualifies leads, books appointments, follows up on quotes and estimates, and helps small business owners go from missing half of their business to capturing all of it.

With 15,000+ paying customers, default profitability, and backing from some of the world’s best investors (Founder’s Fund, 8VC, Human Capital, etc.), Hearth is focused on bringing AI to the trades.

At Hearth we are committed to making a meaningful impact on home improvement professionals across America and every PR you merge will be in furtherance of this goal. We are driven by our customers and the features you ship will have immediate meaningful impact. This role is for strong engineers that want more than just to write “good” code but also are looking to help create something with real impact.

At Hearth customer feedback is taken seriously and acted on, we are obsessed with building the best possible version of our software.
