Artificial intelligence continued to dominate construction technology investment activity at the end of 2025, with six contech startups securing a combined $124.5 million in new funding during the fourth quarter. Investors targeted platforms focused on streamlining permitting, preconstruction, scheduling, procurement and design optimization as contractors seek greater speed, accuracy and predictability.
The latest funding rounds highlight growing confidence in AI-assisted solutions that address persistent industry challenges such as labor shortages, regulatory delays and increasingly complex project delivery requirements.
New York City–based PermitFlow raised $54 million in Series B funding in a round led by Accel, with participation from Kleiner Perkins, Felicis and existing investors. Founded in 2021, the company uses artificial intelligence to simplify the permitting process by leveraging a proprietary database of more than 12 million permitting data points.
PermitFlow’s platform includes AI-powered agents that automate workflows and a submission agent designed to help contractors complete and file permit documents directly. The company plans to use the new funding to expand its team and scale its operations nationwide.
Attentive.AI, headquartered in Wilmington, Delaware, secured $30.5 million in Series B funding led by Insight Partners, with participation from Vertex Ventures, Tenacity Ventures and InfoEdge Venture Fund. The company operates Beam AI, a takeoff software platform serving more than 1,100 construction firms.
Beam AI combines artificial intelligence with a human-in-the-loop quality assurance model, allowing users to upload plans, define scopes and receive reviewed quantity takeoffs. The funding will support the development of next-generation AI products and expansion into new markets.
San Francisco–based Unlimited Industries raised $12 million in seed funding in a round co-led by Andreessen Horowitz and CIV. The company describes itself as an AI-native construction firm, with a platform capable of generating and evaluating hundreds of thousands of design configurations simultaneously.
The technology is designed to optimize layouts based on cost, safety and performance metrics before construction begins. The company plans to use the funding to accelerate growth and further enhance its proprietary AI capabilities.
ConCntric, based in Greenbrae, California, closed a $10 million Series A round led by 53 Stations with participation from Argonautic Ventures and strategic investors. The company offers an AI-powered preconstruction platform that centralizes workflows, data and collaboration in a single workspace.
With the new capital, ConCntric plans to expand its product features—particularly its agentic AI tool, Amplify—and grow teams across customer success, sales, marketing, product and engineering.
San Francisco–based Kojo received a $10 million Series C extension from Wesco International, a Pittsburgh-based distribution and logistics firm. Kojo provides AI-driven materials and inventory management tools for construction projects.
As part of the investment, Kojo’s AI capabilities will integrate with Wesco’s distribution network, enabling real-time material tracking, reduced manual data entry and AI-assisted procurement, scheduling and distributor coordination.
Planera, a construction scheduling software provider based in Pleasanton, California, raised $8 million in additional funding as it expanded services for data center construction clients. Customers include Ralph L. Wadsworth Construction and Ryan Cos.
The company has formed a dedicated service team with data center expertise and introduced new AI tools designed to identify potential delays early and uncover opportunities to accelerate project timelines.
Together, the funding rounds signal sustained investor interest in AI-driven construction technologies that improve preconstruction accuracy, reduce risk and compress schedules. As owners demand faster delivery and contractors navigate tighter margins, digital platforms that automate planning, permitting and procurement are increasingly viewed as essential infrastructure for the modern jobsite.
