Nidus raises $30 million from Costanoa and Kleiner Perkins to train robots for defense manufacturing

Nov 10, 2026
The New York startup, founded by ex-Vannevar engineers, trains robot AI on teleoperation data, starting with wire harness production, and reports $1 million-plus in bookings.

Nidus raised $30 million across pre-seed and seed rounds, according to Upstarts. Costanoa led the pre-seed round, while Kleiner Perkins led the seed round.

The New York startup collects data from people operating robotic arms, then uses that data to train AI models for defense manufacturers. Its initial work focuses on wire harness production, including tasks such as cutting and preparing wires.

Founded this year by former members of defense startup Vannevar's hardware team, Nidus says it has reached more than $1 million in bookings with unnamed defense industrial customers. It plans to use the funding to hire at its New York headquarters and ramp up data collection and training.
