Higharc lands $95M Series C to scale AI homebuilding platform

Higharc, a Durham, North Carolina-based developer of AI-powered software for the homebuilding design-to-construction lifecycle, has secured a $95 million Series C round. The financing was led by Insight Partners, with participation from Wellington Management and existing backers including 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. The raise, announced on June 30, 2026, brings Higharc’s total funding to more than $170 million, according to the company and multiple reports.

The fresh capital will be used to scale Higharc’s AI product development and broaden adoption of its platform across the homebuilding market, including extending its estimating capabilities into the building-materials supply chain. Higharc’s software replaces traditional CAD and fragmented point solutions with a generative system that converts static floorplans into detailed 3D spatial data and automates design, estimating and sales workflows for builders. The company has reported that customers are reducing product-development timelines from months or years to weeks or days, cutting time to community opening by 25–50%, and increasing margins by 10–15%. The Series C round underscores growing investor interest in vertical AI platforms that leverage proprietary construction and homebuilding data to improve efficiency and profitability in residential development.
