Warehouse automation company Nimble Robotics today announced that it has raised a $50 million Series A. Led by DNS Capital and GSR Ventures and featuring Accel and Reinvent Capital, the round will go toward helping the company essentially double its headcount this year.

Founded by former Stanford PhD student Simon Kalouche, the system utilizes deep imitation learning – a popular concept in robotics research that helps systems map and improve through imitation.

“Instead of letting it sit in a lab for five years and creating this robotic application before it’s finally ready to deploy to the real world, we deployed it today,” says Kalouche. “It’s not fully autonomous – it’s autonomous maybe 90, 95% of the time. The other 5–10% is assisted by remote human operators, but it’s reliable on day one, and it’s reliable on day 10000.”
