Tutor Intelligence raises $75M Series B for warehouse robot fleets

2 November 2026: Tutor Intelligence, a Watertown, Massachusetts company whose robots move and pack goods in warehouses and factories, says it has raised a $75 million Series B led by Andreessen Horowitz. SiliconANGLE reports that Union Square Ventures and Neo, which led the company's previous two rounds, also took part, and that the money goes into better AI models and faster production of robots.

Not yet independently verified. Tutor Intelligence's own post is undated and names only Andreessen Horowitz; SiliconANGLE calls the round a Series A while the company's site says Series B, and we follow the company. The other investors and the use of the money come from SiliconANGLE. We will update this when it can be confirmed, and remove this note.

Robots that go to work before they are autonomous

Tutor calls itself a robotics research and deployment company that builds its own robot hardware, deploys ahead of autonomy and uses human "tutors" to train robot foundation models from real work. When a robot meets a case it cannot handle, a remote person guides it, and every such action becomes training data. The company's bet, set out by Gruenstein in its post, is that the number of tutors can grow more slowly than the number of robots as the models improve, which is what would make the approach pay at scale.

SiliconANGLE describes two machines. Cassie is a mobile arm that moves packages between pallets and containers at up to 18 items a minute; Sonny is a two-armed robot on wheels that picks and packs. Palletising and depalletising lead the company's own list of applications. Tutor's site prices both robots from $14 an hour, charged by the hour or by the pick on month-to-month terms with support and model updates included, or sold outright with an annual service plan, so on the usage plan Tutor carries the cost of a robot that stands idle.

A founder's case for more robots now

Gruenstein's post argues that robots are still "a rounding error" in the physical economy. He writes that the United States put 38,000 robots into businesses in 2025, against a population of 340 million, and that roughly nine in ten US factories and warehouses have no robot at all. His co-founder, named in the post only as Alon, incorporated the company with him in February 2021; Gruenstein traces the idea to his student years at MIT.

"Tutor's mission is to proliferate robotics for the common good," Gruenstein writes. SiliconANGLE reports that the number of facilities using Tutor's robots nearly quadrupled over the past year; the company gives no customer count.

Where Tutor sits among robot makers

Warehouse picking and palletising is one of the most crowded corners of commercial robotics, and pricing models differ as much as the hardware. A usage-based contract with remote tutors behind it also means the warehouse depends on the vendor's people and software for as long as the robots stay, which belongs in any service-level agreement: response times for a stuck robot, and who sees the data its work produces.

Our catalogue lists 60 robot manufacturers, 25 robotics integrators and 21 warehouse management products, the systems a picking robot has to take its orders from.
