Homebuilding AI company Higharc announced June 30 that it raised $95 million in Series C funding and entered a partnership with lumber and building materials distributor US LBM.

The funding round was led by software investor Insight Partners, with participation from Wellington Management and existing investors 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 round brings Higharc’s total funding to more than $170 million.

Durham, NC-based Higharc said the new funding will support AI product development and help expand its platform to a broader segment of the homebuilding market.

The company also announced its AI Estimating product for building materials distributors, with US LBM as its first partner. Higharc said the offering gives lumber and building materials distributors and dealers the ability to generate material takeoffs from builder plan sets at enterprise scale.

Higharc’s AutoTranslate AI translates floorplan images into 3D spatial data models, combining AI vision models with construction logic to generate quantity estimates and align them to purchasable materials. The company said the resulting estimates reflect how homes are designed and built, rather than approximations.

“With advanced technology accelerating the building materials industry, what sets Higharc apart for US LBM is the ability to go from a static 2D plan to a precise and dynamic 3D data model in one step,” US LBM Chief Digital and Technology Officer Jonathan Greene said in the announcement. “That unlocks not just fast, accurate quoting but smarter material planning, the ability to sell the whole home and real-time collaboration with our customers — powering better outcomes for us, the builder and ultimately the homeowner.”

With $6.8 billion in 2025 revenue US LBM is one of the largest building products distributors in the United States and No. 5 on MDM’s 2026 Top Distributors List for Building Materials/Construction, operating more than 450 locations nationwide. Through its local divisions, the company provides a wide range of building materials to custom home builders, national builders and specialty contractors.

Higharc said its platform helps homebuilders automate design, estimating and sales workflows, producing construction documents, real-time estimates and shoppable 3D home models.
