Unlimited Industries, a California-based AI construction company, has raised $12 million in seed funding co-led by Andreessen Horowitz and CIV. The company uses AI to automate engineering design for large-scale infrastructure projects, reducing pre-construction time from months to days whilst cutting costs significantly. Founded by Alex Modon, Tara Viswanathan and Jordan Stern, Unlimited operates as an AI-native construction firm that both designs and builds. Its proprietary platform generates and evaluates hundreds of thousands of design configurations simultaneously, optimising for cost, safety and performance. On recent projects, the company reduced pre-construction engineering from six months to weeks and cut projected capital costs by over 50%. The startup is initially focusing on power infrastructure for data centres, critical minerals and advanced manufacturing projects across the United States.
