Tutor Intelligence raises $75 million to put more robots to work by the hour

Tutor Intelligence, a robotics research and deployment company in Watertown, Massachusetts, announced on Monday, Nov. 2, 2026, a $75 million Series B led by Andreessen Horowitz, bringing its total raised to $117 million.

The robotics industry keeps arguing about which model architecture wins; Tutor's bet is that the robot that is already working, with a human quietly helping, collects the data everyone else is missing. Selling robot labor by the hour is clever because it turns a capital request into a staffing line. The open question is how much of that $14 an hour is still a human on a joystick, and how fast that share shrinks.

Tutor Intelligence raised a $75 million Series B led by Andreessen Horowitz. A Series B is a later funding round, after a company already has a product out in the world. Union Square Ventures, which led the Series A, and Neo, which led the seed, also participated. A Series A is the round before this one. A seed is the earlier round that got the company started. The total raised is $117 million. Those figures are the company's.

The money funds training of Tutor's robot foundation model, plus manufacturing and deployment of its two robot workers, Sonny and Cassie, which run the company's own models. A foundation model is a broad model the company then points at particular jobs. Those lines are Tutor's.

Tutor puts fleets of internet-connected robots into real factories and warehouses, where remote human operators, which the company calls tutors, step in. Every completed task produces real-world training data that is used to train better models. The company was founded out of MIT CSAIL, the computer-science and artificial-intelligence lab at the Massachusetts Institute of Technology. Those lines are the company's.

Cassie is a single-armed mobile robot for palletizing, depalletizing, and case picking. Palletizing is stacking cases onto a pallet. Depalletizing is taking them off. Case picking is selecting the cases an order needs. Sonny is a mobile two-armed robot whose first job is e-commerce order picking, taking individual items for an online order. Those descriptions are Tutor's.

Customers pay by the hour for palletizing and depalletizing, or by the pick, from $14 an hour. Fourteen dollars an hour is the starting rate on the pricing page for that rented robot work. There is no upfront purchase and no long-term contract. Tutor handles deployment, maintenance, and model updates. The pricing page lists a minimum of 80 hours per month, an $8,000 refundable deposit, and a $10,000 flat implementation fee for Cassie on palletizing. A minimum of 80 hours means the smallest monthly booking on that page is 80 hours. The deposit is money the customer puts down and can get back. The implementation fee is a one-time charge to set the robot up. The robots can also be bought outright, with an annual service plan. Those terms are the pricing page's and the announcement's.

Tutor says its robots now work in almost four times as many facilities as a year ago. Almost four times means close to four sites now for each site a year ago. The company says it is on track for more than 1,000 robots under contract by the end of 2027, all built in and deployed from the United States. Nearly a third of organizations that got Tutor robots in the past 12 months were existing customers adding more. Nearly a third means a bit under one in three of those organizations. The robots handle goods such as breakfast cereals, snacks, candy, cosmetics, home goods, and toys. Those lines are the company's.

Josh Gruenstein, co-founder and CEO, said: "We can hardly build robots fast enough." Raghu Raghuram, general partner at Andreessen Horowitz and former CEO of VMware, said: "Continual learning across an expanding range of deployments is the path from specialized capabilities to general-purpose robotics." Continual learning means the model keeps getting better as the robots do more jobs. A general-purpose robot, in that sentence, is one that can take on many kinds of work. Those quotations are theirs.

In plain terms, Tutor raised $75 million, led by Andreessen Horowitz, to build more Sonny and Cassie robots and to train the model that runs them. A business can rent the work from $14 an hour, with a remote person able to step in, instead of buying the machine. The company says it is aiming for more than 1,000 robots under contract by the end of 2027.
