Rebar is an AI-powered construction technology company founded in 2024 that automates the processing of construction documents - such as blueprints and spec books - for commercial HVAC, electrical, and plumbing suppliers and subcontractors. Its proprietary platform uses computer vision, layout analysis, and AI-powered document processing to extract critical data and generate accurate quotes in minutes, a process that has historically taken days or weeks of manual effort. The system has scaled to over 500 quotes per day across thousands of projects in North America, including billion-dollar construction projects.
The company's products include a vertical AI platform for construction document processing and hyper-specialized HVAC estimating software designed to enable inside staff to perform takeoffs quickly. Rebar's work in the space has been recognised with a 2026 AHR Innovation Award.
Rebar raised a $14 million Series A and operates from New York, NY, serving customers across North America. The company sits at the intersection of AI research and the commercial construction industry, applying advanced machine learning techniques to a domain where document complexity and volume have traditionally required significant manual labour.
