SAN FRANCISCO, CA, Dec 4, 2025 – Unlimited Industries, a California-based company using AI to modernize construction projects, has raised $12 million in seed funding. The investment will support the company’s work on U.S. energy facilities, data centers, manufacturing plants and mineral infrastructure. The round was co-led by Andreessen Horowitz and CIV, with participation from other investors. Unlimited plans to use the funding to develop its AI platform.
“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”
Unlimited Industries was founded by Alex Modon, who launched the company after working in industrial construction. His project experience exposed slow design cycles, fragmented workflows and limited ability to test design options. That led him to the idea that newer AI models could generate and compare large sets of design configurations, allowing infrastructure projects to be planned and executed with greater technical rigor. He partnered with co-founders Tara Viswanathan and Jordan Stern. The two joined Modon and established Unlimited’s leadership team.
Unlimited has used its AI tools on a number of industrial projects. One project reduce pre-construction engineering from six months to few weeks. Another project used the company’s Ai platform to evaluate design options that reduced projected capital costs by more than 50%. Each project adds data that updates the system’s models, cost data and workflows. The company is focusing on U.S. power and infrastructure needs for data centers, minerals and manufacturing projects. It works with both public companies and energy start-ups.
Unlimited brings its design and construction teams under one roof, allowing engineers to run design iterations at low cost. The approach supports continuous design adjustments instead of the fixed plans used under cost-plus contracts.
“The engineering and construction industry has remained largely unchanged for decades,” said Katherine Boyle, general partner at Andreessen Horowitz. “Unlimited’s vertically integrated, AI-first approach represents a paradigm shift, turning design and build into a rapid and continuous optimization problem. This is exactly the kind of innovation needed to restore America’s ability to build ambitious infrastructure at scale.”
“We are in the midst of the largest infrastructure buildout of our generation, but constrained by our existing resource base,” says Abhijoy Mitra, co-founder & managing partner at CIV. “The only way to have our existing workforce meet this moment is to amplify their impact with the latest advancements in AI. Unlimited is building the platform to accomplish this at scale today.”
Unlimited’s mission is to change how industrial projects are designed and built in the United States. The company plans to use software-driven process and integrated teams to support decisions and adaptable designs. Its vision centers on making construction responsive and aligned with U.S. infrastructure needs.
