About us

Building the AI operating system for the trades.

Rebar helps HVAC, plumbing, and electrical pros move faster — from takeoff to bid.

How we got here

The trades build the physical world – the software industry forgot about them.

For decades, construction tech has served owners and general contractors. The subcontractors and suppliers who actually execute the work — HVAC, plumbing, electrical — have been left with PDFs, highlighters, and pen-and-paper workflows.

02. The origin

Stale Growth

Co-founder Evan Brown grew up in his uncle's HVAC supplier office, watching estimators spend full weeks on quotes that should take hours. Years later, as an estimator himself, nothing had changed.
