Higharc, the Durham, N.C. homebuilding AI company, closed a $95 million Series C on June 30, 2026, led by a global software investor. The company used the announcement to extend its Estimating AI product to materials distributors and named US LBM as a new partner in that channel.
Where the Materials Flow
Higharc describes its platform as covering the full design-to-construction lifecycle for homebuilders. That framing has centered on the builder — the party responsible for design, permitting, and construction management. Extending Estimating AI to materials distributors adds a distinct class of user: the companies that hold building materials inventory and fulfill the orders generated during a builder's design and estimating process.
Distributors sit between manufacturers and job sites. They are the parties that absorb timing and quantity mismatches when a builder's material plan diverges from what actually gets ordered. Pulling AI-driven estimation data into that layer gives distributors earlier visibility into what builders will need — before the purchase order, not after.
US LBM as the Anchor Relationship
US LBM is a building materials distributor. The Higharc partnership names US LBM as the entry point for the distributor-channel expansion. The announcement does not detail the commercial structure, technical integration, or scope of the arrangement.
The $95 Million Round
The Series C was led by a global software investor. The announcement does not name the lead firm, disclose additional participants in the round, or include a post-money valuation.
The distributor push follows a pattern common to vertical software companies building in construction: establish the primary platform with the builder, then extend toward the adjacent players — in this case materials distributors — who depend on the same underlying design and cost data. Whether the US LBM relationship is exclusive or a template for a broader distributor network is not addressed in the source.
