Higharc Raises $95M in Series C Funding Led by Insight Partners

The round also saw participation from Wellington Management, Fifth Wall, Spark Capital, Lux Capital, and SE Ventures. The round brought total capital raised to more than $170 million.

The company plans to use the funding to expand its AI product development, grow its platform for more residential housing customers, and add more building materials suppliers to its network.

At the same time, Higharc announced a partnership with US LBM, the largest private distributor of lumber and building materials in the U.S. The agreement expands Higharc’s platform into the building materials supply chain.

The homebuilding industry is increasingly adopting AI to handle complex design, 3D modeling, and estimating tasks. Work that once took weeks to complete manually can now be automated, helping builders, and suppliers work faster and more efficiently.

While AI is transforming technical work across industries, many AI systems still struggle with spatial reasoning. In homebuilding, this can lead to construction delays, excess materials, costly change orders, and a poor customer experience. Higharc addresses this by creating homes as structured digital models that include building codes, construction standards, and geometry.

Higharc replaces AutoCAD and other standalone tools with a single platform that automates home design, estimating, and sales. Its AI-powered system helps builders create accurate, construction-ready home plans with detailed documents, real-time cost estimates, and interactive 3D models.

As part of its expansion, Higharc has launched AI Estimating for building materials distributors, with US LBM as its first partner. Estimating materials for buildings has traditionally been a complex, manual process that often leads to errors and delays. The new product helps distributors and dealers generate accurate material takeoffs from builder plan sets at large scale.

The system is powered by Higharc’s AutoTranslate AI, which converts floorplan images into detailed 3D digital models. By combining AI vision technology with construction-specific logic, it produces precise material quantity estimates and connects them directly to purchasable products, creating estimates that closely match how homes are actually designed and built.

"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," explained Minor.

"We evaluate AI companies across every sector, and Higharc stands out as a clear leader in applying AI to residential construction," said Josh Fredberg, Managing Director at Insight Partners. "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."

"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," said Jonathan Greene, Chief Digital and Technology Officer at US LBM.

"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," said Kyle Bear, VP of Research and Development at Signature Homes. "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."
