Rebar has secured $14 million in Series A funding as it expands its AI platform for the HVAC, electrical, and plumbing industries. The round was led by Prudence, with participation from Zero Infinity Partners, Founder Collective, Villain Capital and Optimist Ventures.

The company launched commercially less than a year ago and is already working with large enterprise customers managing thousands of projects each month. Its focus is simple. Reduce the time and effort required to generate construction quotes.

A $14M push to scale AI in construction workflows

The new funding gives Rebar resources to grow its platform and increase adoption among contractors and distributors. Prudence led the investment, joined by Zero Infinity Partners, Founder Collective, Villain Capital and Optimist Ventures.

Rebar is positioning its software as a central operating system for construction trades such as HVAC, electrical and plumbing. The company focuses on workflows that remain heavily manual despite decades of digital tools.

Construction quoting is a clear example. It often requires reviewing large sets of architectural drawings and specification documents before any price can be produced.

Why quoting remains one of construction’s slowest processes

Generating a quote for a project is one of the most time consuming tasks contractors face. Teams frequently review hundreds of pages of plans and specification books before calculating costs.

Many digital tools still mirror the same manual steps that contractors once performed with pen and paper. The result is a process that can take hours or days for a single estimate.

“I spent years completing estimates by hand and have a deep understanding of this process that industry participants deal with every day. This is a pain point that previously seemed unsolvable with legacy technology, but leveraging our proprietary AI platform, contractors and distributors can spend less time buried in back office work and more time with customers, winning new business.”

Evan Brown, CEO of Rebar.

Rebar approaches the problem differently. Its vertical AI platform analyzes blueprints and project documents, extracting tens of thousands of data points from each project. That information is then used to automate estimating and quoting.

Expanding the platform across trades and regions

Rebar plans to use the new capital to broaden its operating system and add new AI driven tools that support additional workflows across the HVAC ecosystem.

The company is also preparing to extend its platform beyond HVAC into electrical and plumbing sectors. Geographic expansion is another priority, with growth planned across the United States and international markets.

“HVAC, electrical and plumbing are massive end markets that have historically had very little purpose built technology and rely mainly on manual processes. By leveraging Rebar’s proprietary AI platform, these businesses are leapfrogging software and adopting a solution that is orchestrating and automating end to end workflows. This is orders of magnitude better than anything this end market has seen before and is both a cost saver and revenue generator. The Rebar team is perfectly positioned to capitalize on this opportunity with their mix of industry expertise and deep technical capabilities.”

Jordan Viniar, General Partner at Prudence.

The company behind the platform

Rebar develops AI software designed specifically for contractors and distributors working in the HVAC industry. Its models process construction documents and automatically produce estimates and quotes that once required extensive manual review.

By reducing the time required to produce a quote, the company argues that contractors can submit more bids, lower operating costs, and improve their chances of winning projects.

Rebar began commercialization less than a year ago and already supports enterprise customers across thousands of monthly projects.
