Unlimited Industries, a California-based company using AI for infrastructure construction, has raised $12 million in seed funding.
The round was co-led by Andreessen Horowitz and CIV, with participation from industry investors. The capital is intended to accelerate Unlimited’s expansion and develop its proprietary AI platform – one designed to make large-scale engineering and construction faster, cheaper, and more ambitious.
Unlimited is an AI-native construction company that designs and builds with a proprietary platform that generates and evaluates hundreds of thousands of design configurations in parallel, automatically identifying layouts for cost, safety, and performance before construction begins. By integrating AI-driven design with its own vertically integrated engineering and construction teams, Unlimited said it eliminates the costly handoffs and misaligned incentives that have defined the industry for decades.
The company was founded by Alex Modon, a multidisciplinary engineer and repeat founder who entered the world of industrial construction only to discover how outdated it was. On his first major project in one of the most construction-friendly regions of Texas, he found a system mired in inefficiency, misaligned incentives, and inertia. Projects that should have taken months dragged on for years, and each step relied on disconnected tools and manual processes that made it impossible to iterate quickly. The experience led to a realization: with the advent of powerful new AI models, physical infrastructure could finally be built the way software is built. That idea became Unlimited.
Across the United States, a new industrial age is taking shape. Trillions of dollars in infrastructure, from energy projects and advanced manufacturing to data centers and critical mineral facilities, must be built in the next decade. But large construction projects are slower and more expensive today than they were half a century ago. to change that.
“Advances in AI mean we can finally build the physical world the way we build software,” said Alex Modon, Co-Founder and CEO of Unlimited Industries. “The traditional construction model is slow, brittle, and fundamentally misaligned. Our 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”
