Rebar, a startup building an AI operating system for commercial HVAC suppliers, has raised $14 million in a Series A funding round, it tells Crunchbase News exclusively.

Prudence led the financing for the New York-based company. Zero Infinity Partners, Founder Collective, Villain Capital and Optimist Ventures also participated in the round.

Founded in October 2024, Rebar says it uses artificial intelligence to help commercial HVAC suppliers generate quotes on average 60% to 70% faster than traditional methods.
