Higharc, an AI platform for the homebuilding design-to-construction lifecycle, has raised a $95 million Series C led by Insight Partners, bringing its total funding to more than $170 million. Alongside the funding, the company announced a partnership with US LBM, the largest private distributor of lumber and building materials in the U.S., expanding Higharc’s platform into the building materials supply chain.
CEO and co-founder Marc Minor said AI is reshaping how builders operate by automating complex design, estimating and sales workflows that traditionally required extensive manual effort. Higharc’s platform generates homes as spatial data models that capture code requirements and construction geometry, aiming to avoid the spatial reasoning errors common in other AI systems. The company reports that customers have seen faster product development timelines and improved margins.
As part of its expansion, Higharc introduced an AI Estimating product for building materials distributors, with US LBM as its first partner. The tool, powered by Higharc’s AutoTranslate AI, converts floorplan images into 3D spatial data models to generate material quantity estimates aligned with actual construction plans. Jonathan Greene, Chief Digital and Technology Officer at US LBM, said the capability enables faster, more accurate quoting and improved collaboration across the supply chain.
The funding round included participation from Wellington Management, Fifth Wall, Spark Capital and Lux Capital, among other existing investors.
