Tutor Intelligence, a US-based robotics research and deployment company, has raised $75 million in a Series B funding round led by Andreessen Horowitz, with participation from Union Square Ventures and Neo. The investment brings the company’s total funding to $117 million.
Founded in 2021 by Josh Gruenstein and Alon Kosowsky-Sachs, Tutor Intelligence is headquartered in Watertown, Massachusetts. The company develops AI-powered robots for industrial operations, combining robotic hardware, foundation models and real-world deployment systems. Gruenstein serves as co-founder and CEO.
Tutor Intelligence operates a robotics platform that places internet-connected robots in manufacturing facilities and warehouses. Its systems perform physical tasks with support from remote human operators, known as tutors, who intervene when assistance is needed. Data generated through these operations is used to train the company’s AI models and improve robot capabilities over time.
The company’s robotic workforce includes Cassie and Sonny. Cassie is designed for material-handling operations, including case picking, palletizing and depalletizing. Sonny is a two-armed robot developed for tasks requiring greater dexterity, including individual-item picking in fulfillment environments. Both systems use Tutor Intelligence’s robotics models.
Tutor Intelligence offers its robots through usage-based pricing arrangements, allowing businesses to pay by the hour or by the pick. Under these arrangements, customers can deploy robotic systems without purchasing the equipment upfront or entering long-term contracts. The company manages deployment, maintenance and software updates.
According to Tutor Intelligence, its robots now operate in nearly four times as many facilities as a year earlier. The company also reported that nearly one-third of organizations receiving its robots during the preceding 12 months were existing customers expanding their deployments. It is targeting more than 1,000 robots under contract by the end of 2027.
The new funding will support further development and training of Tutor Intelligence’s robot foundation models, alongside increased manufacturing and deployment of Cassie and Sonny.
The Series B follows a $34 million Series A announced in December 2025, led by Union Square Ventures and co-led by Fundomo, with participation from Neo.
