Unlimited Industries, a San Francisco-based AI-native construction company, has raised $12m in seed funding to accelerate its mission to redesign how the United States builds infrastructure. The round was co-led by Andreessen Horowitz and CIV, with participation from other leading investors.
The company’s proprietary platform automates engineering design, allowing it to evaluate hundreds of thousands of potential configurations in parallel and identify optimal layouts for cost, safety, and performance. By integrating design and construction under one roof, Unlimited aims to cut project costs by millions and reduce pre-construction timelines from months to days.
Alex Modon, Co-Founder and Chief Executive of Unlimited Industries, said the approach “replaces static design choices with a dynamic, data-driven process that learns from every project. The result is faster, cheaper, and more successful projects.”
Founded in 2025 by Modon alongside Tara Viswanathan and Jordan Stern, the company is tackling the inefficiencies endemic to industrial construction. On a recent project, Unlimited reduced pre-construction engineering time from six months to a few weeks and identified a design that cut projected capital costs by more than 50%. Each project further strengthens its AI platform, creating a continuous optimisation loop.
Traditional construction firms often profit from delays through cost-plus contracts and change orders. Unlimited’s model ties incentives to measurable outcomes, allowing near-infinite design iterations at marginal cost close to zero.
Katherine Boyle, General Partner at Andreessen Horowitz, described Unlimited’s approach as a “paradigm shift, turning design and build into a rapid and continuous optimisation problem.” Abhijoy Mitra, Co-Founder and Managing Partner at CIV, added that the firm’s platform “amplifies the impact of the existing workforce with the latest advancements in AI.”
Unlimited is initially focused on energy infrastructure, data centres, critical mineral facilities, and advanced manufacturing, partnering with both century-old companies and emerging energy startups. Its broader mission is to make American industrial construction agile, software-driven, and capable of meeting the nation’s most ambitious infrastructure goals.
