Higharc, a Durham, NC-based AI-native homebuilding cloud platform, has raised $95M in Series C funding led by Insight Partners. The platform replaces disconnected tools like AutoCAD, spreadsheets, and PDFs with one connected system for designing, estimating, selling, and building homes using spatial AI that generates live 3D data. Total funding now exceeds $170M. The capital will scale AI product development and expand the platform into the building materials supply chain.
AI Funding Arrives for Fragmented Homebuilding
The timing comes amid labor shortages and margin pressure in residential construction. Higharc simultaneously announced a partnership with US LBM, the largest private lumber and building materials distributor, to deploy AI estimating across the supply chain. Its approach generates homes as structured 3D data models that automatically produce construction documents, material takeoffs, and interactive buyer experiences from a single source.
Legacy CAD Workflows Create Costly Delays
Homebuilders still rely on 41-year-old CAD line-drawing methods and disconnected point solutions. This creates version sprawl, manual re-entry errors, and slow cycles from concept to permit. Only 1.5% of construction firms currently use AI despite the scale of the $1.7T US homebuilding industry.
Spatial AI Replaces Line-by-Line Drafting
Higharc built a Generative Building Model that treats buildings as structured tokens rather than pixels or text. The system converts any floorplan into BIM-native 3D data in minutes, then updates estimates, sales visuals, and permit documents in real time. It explicitly contrasts with generic frontier models that struggle with construction precision and rules.
As Michael Bergin, co-founder and Chief R&D Officer, noted:
"Builders have been promised AI and automation before, but they've gotten tools that look impressive in a demo and fall apart on a real plan set."
Insight Partners Leads Category Bet
Insight Partners led the round with participation from Wellington Management and existing backers including Fifth Wall, Spark Capital, Lux Capital, Home Depot Ventures, and SE Ventures. The investor mix signals conviction in vertical AI for a massive but underserved industry. The simultaneous US LBM deal shows the platform is extending beyond builders into supply chain workflows.
Construction Software Market Accelerates
The construction software market stands at $11.78B in 2026 and is projected to grow at 9.7% CAGR. Higharc's $170M+ total funding positions it to capture share as builders replace fragmented tools. Named competitors include Homebound, which raised $75M Series C in 2022, and Welcome Homes, which has raised approximately $54M. Hyphen Solutions and Procore operate in adjacent construction management segments without generative design for residential production.
Quantified Builder Results Drive Adoption
Signature Homes reported $30M in additional revenue and $6M gross profit since deploying the platform. New Home Inc. saves $1,840 per home. HistoryMaker Homes reduced plan-to-permit time from over two months to 19 days. These outcomes explain why production builders from regional firms to public companies like Tri Pointe Homes are adopting the system.
