Nidus Technologies, a startup building foundation robotics models for precision assembly, raised $30 million in seed funding announced November 10, 2026. Kleiner Perkins and Costanoa led the round, with participation from Ludlow Ventures, SF1, Absolute Partners and Tau, according to a company announcement.
What problem is Nidus actually solving?
Wire harness assembly -- the bundles of cables that route power and signals through vehicles, aircraft and weapons systems -- is still done almost entirely by hand, because the wiring differs on nearly every unit and robots have historically struggled with that kind of variation. Nidus built what it calls foundation robotics models: AI systems trained to generalize across different wiring configurations rather than needing to be reprogrammed for each one.
The company's current deployments run on a proprietary platform designed to meet U.S. Department of War security requirements, since its customers are American defense manufacturers that can't run foreign-hosted software on production lines handling military hardware.
Who is backing Nidus, and who's leading it?
Kleiner Perkins and Costanoa co-led the $30 million seed, with Costanoa doubling down after backing an earlier pre-seed round. Ludlow Ventures, SF1, Absolute Partners and Tau also participated, alongside angel investors including Hadrian founder Chris Power, Dulo's Adrian Aoun, and Archer Chief Commercial Officer Nikhil Goel -- all founders or executives from other hardware and defense-tech companies.
CEO and co-founder Justin Sealy, who grew up in rural South Carolina and says he watched industrial jobs leave the region, framed the mission around reshoring: "We believe in a future where American industry is self-sustaining and no longer dependent on foreign production."
How is Nidus already performing, and what happens next?
The company said it crossed seven figures in revenue within its first four months of commercial deployment, with its models already running customized wire-harness jobs for U.S. defense manufacturers it declined to name. That is a notably fast ramp for a robotics startup still at the seed stage.
The new capital will fund engineering hires and an expansion beyond wire-harness work into other factory tasks, the company said. Nidus is entering a crowded field of startups chasing "embodied intelligence" for manufacturing, but its early focus on a narrow, defense-specific task -- rather than a general-purpose humanoid -- is the kind of wedge investors have rewarded elsewhere in industrial robotics.
How does this compare to other embodied-intelligence raises?
Nidus's $30 million seed is modest next to the nine- and ten-figure rounds some humanoid and foundation-model robotics companies have landed this year, but it's sizable for a company still generating single-digit-million revenue. The bet from Kleiner Perkins and Costanoa is that a tightly scoped product -- automating one specific, labor-starved task inside defense supply chains -- can scale into adjacent factory work faster than a platform trying to do everything at once.
Watch for whether Nidus names its defense-manufacturer customers as it grows, and whether its expansion into "additional factory workflows" stays within wiring and cabling or branches into unrelated assembly work.
