Higharc, a Durham, North Carolina-based homebuilding software company, closed a $95 million Series C led by Insight Partners, bringing its total funding to more than $170 million, the company announced June 30.
Wellington Management, Fifth Wall, Spark Capital, Lux Capital, SE Ventures, Simpson Strong-Tie, PSP Partners, RXR Arden Digital Ventures, Suffolk Technologies, Vertex Ventures, NC Tweener Fund and MetaProp also participated in the round. Higharc did not disclose a valuation.
The company’s platform generates homes as 3D spatial databases rather than static drawings, capturing code requirements, construction standards and geometry in a structured model that builders can use to automate design, estimating and sales workflows. Its AutoTranslate tool converts an existing 2D floorplan image into that same 3D data model in a single step, according to the company.
Higharc is using part of the round to expand beyond homebuilders and into the building materials supply chain. The company named US LBM, the largest private distributor of lumber and building materials in the U.S., as the first partner for its new AI Estimating product.
“What sets Higharc apart is the ability to go from 2D plan to 3D data model in one step,” said Jonathan Greene, chief digital and technology officer at US LBM.
Higharc CEO and co-founder Marc Minor said the company’s own customer data shows the shift has moved past pilot projects. “AI isn’t just assisting builders. It’s reshaping how builders work, cutting time and cost per job,” Minor said.
Higharc reports that builder customers have cut time to community open by 25% to 50% and increased margins by 10% to 15%, though those figures come from the company rather than an independent audit. Kyle Bear, vice president of R&D at Signature Homes, credited the platform with skipping the rework other design tools require, saying its “outputs are usable from day one.”
The company was named to Deloitte’s Technology Fast 500 and Fast Company’s Most Innovative Companies list for 2026. Higharc has not disclosed current revenue or customer count.
