US robotics company Nidus has closed a $30 million funding round led by Kleiner Perkins and Costanoa, with participation from Ludlow Ventures, SF1, Absolute Partners, Tau, and angel investors including Hadrian founder Chris Power, Dulo co-founder Adrian Aoun, and Archer Chief Business Officer Nikhil Goel. Nidus develops foundation robotics models that enable traditional industrial robots to perform precision assembly tasks using a sovereign AI training approach that allows customers to retain their own knowledge. The company currently delivers custom models on its proprietary platform for wire harness processing automation, built to meet US defense sector security requirements. Nidus reported revenue exceeding seven figures within the first four months since founding. The new capital will fund engineering team expansion, extend capabilities beyond wire harness automation into additional factory processes, and scale deployments with US defense manufacturers.
