Higharc announced it has raised $95 million in Series C funding to scale its AI platform for the homebuilding industry. The round was led by Insight Partners, with participation from Wellington Management and existing investors 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 funding brings Higharc’s total funding to more than $170 million.
Higharc is building AI software for the full design-to-construction lifecycle in homebuilding. The company’s platform helps builders automate complex workflows across design, 3D modeling, estimating, sales, and construction documentation.
The company also announced an agreement with US LBM, the largest private distributor of lumber and building materials in the U.S. The partnership marks Higharc’s expansion into the building materials supply chain.
Higharc said homebuilding is going through a major shift as design, modeling, and estimating workflows move toward AI. The company’s platform is designed to automate work that previously required weeks of manual effort across builder and distributor teams.
Higharc generates homes as spatial databases, capturing code requirements, construction standards, and geometry. This creates a structured data foundation for AI that is designed to produce accurate and build-ready outputs.
The company said its platform replaces AutoCAD and point solutions by enabling builders to automate design, estimating, and sales workflows. Using Higharc’s generative system, homebuilders can produce precise homes with construction documents, real-time estimates, and shoppable 3D models.
Builders across North America use Higharc to speed up design-to-construction workflows. The company said customers have compressed product development timelines from months or years to weeks or days, reduced time to community opening by 25% to 50%, and increased margin by 10% to 15%.
The new funding will support AI product development and expand Higharc’s platform to a broader segment of the homebuilding market.
As part of the expansion, Higharc announced an AI Estimating product for building materials distributors, with US LBM as its first partner. The product enables lumber and building materials distributors and dealers to generate accurate material takeoffs from builder plan sets at enterprise scale.
Higharc’s AutoTranslate AI can translate floorplan images into 3D spatial data models. The system combines proprietary AI vision models with deterministic construction logic to generate precise quantity estimates and align them to purchasable materials.
Higharc said this allows quantity estimates to reflect how homes are actually designed and built, rather than relying on approximations. The company sees this as a way to support faster quoting, smarter material planning, whole-home selling, and real-time collaboration between distributors and builders.
Higharc is headquartered in Durham, North Carolina. The company has been recognized in the Deloitte Technology Fast 500 and Fast Company’s Most Innovative Companies of 2026.
KEY QUOTES:
“AI isn’t just assisting builders. It’s reshaping how builders work, cutting time and cost per job while giving buyers a more personalized experience. The builders and distributors leading the way use AI to automate their most complex workflows unlocking teams to focus on product improvement and customer experience.”
“Everything we’re building is in service of one outcome: to make homebuilding seamless so builders can build better homes more affordably. This next phase is about scaling that impact by deepening our AI capabilities and bringing suppliers onto the same trusted system builders already rely on.”
Marc Minor, CEO and Co-Founder of Higharc
“We evaluated a lot of AI tools, but most produce outputs that require so much correction they’re unusable. Higharc is different. It’s grounded in how homes are actually built, so the outputs are usable from day one. Higharc helps us move faster and operate with more precision and fewer downstream surprises. And as a result, we’re breaking ground on more homes each year while protecting margins and pricing power.”
Kyle Bear, VP of Research and Development at Signature Homes
“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. 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.”
Jonathan Greene, Chief Digital and Technology Officer at US LBM
“We evaluate AI companies across every sector, and Higharc stands out as a clear leader in applying AI to residential construction. Higharc is setting the standard for how homes will be designed, permitted and built in the age of AI. Leading builders are already standardizing on the platform, and we have conviction that this extension into supplier workflows will transform the broader builder supply chain.”
Josh Fredberg, Managing Director at Insight Partners
