Tutor Intelligence Raises $75M to Scale Hourly-Wage Warehouse Robots

Tutor Intelligence, a Watertown, Massachusetts-based startup deploying automated industrial handling systems, has raised a $75 million Series B round led by Andreessen Horowitz, according to reporting by The Next Web .

The round brings total capital raised by the company to $117 million. Prior backers Union Square Ventures, which led the Series A, and Neo, which led the seed round, also joined the financing. Tutor Intelligence did not disclose its valuation or current revenue.

Spun out of MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) by co-founders Josh Gruenstein and Alon Kosowsky-Sachs, Tutor Intelligence builds and operates two robotic systems, named Sonny and Cassie. Rather than selling capital equipment to logistics and manufacturing operators, the company bills clients by the hour or per completed pick, eliminating upfront hardware purchases and long-term service contracts while handling installation, maintenance, and software updates.

The startup's core technical architecture relies on an operational feedback loop. Internet-connected robots perform manipulation tasks across customer facilities—sorting and moving items such as consumer packaged foods, cosmetics, and toys. When unexpected situations occur, remote human operators, whom the company terms tutors, intervene over the network to guide the machines. Each intervention and task completion generates physical interaction data that Tutor Intelligence feeds back into training its proprietary robot foundation models to improve autonomy over time.

"Continual learning across an expanding range of deployments is the path from specialized capabilities to general-purpose robotics," Andreessen Horowitz general partner and former VMware chief executive Raghu Raghuram said regarding the investment.

Tutor Intelligence stated that its machines currently operate in nearly four times as many facilities as they did a year ago, with existing customers representing approximately one-third of new deployments over the past twelve months. The company expects to scale its fleet to more than 1,000 domestic-built robots under contract by the end of 2027, though it has not shared the exact number of units currently in commercial operation.
