What Tutor Intelligence does
Tutor runs fleets of internet-connected robots, called Sonny and Cassie, in customers' factories and warehouses. Remote human operators, known as tutors, guide the robots when needed, and the work they complete generates real-world data that trains the company's models. The robots handle goods such as cereals, snacks, sweets, cosmetics, home goods and toys, The Next Web reported.
Customers do not buy the machines. They pay by the hour or by the pick, with no upfront purchase and no long-term contract, and Tutor handles deployment and maintenance and sends software and model updates. The company describes its customers only as some of the largest manufacturing and logistics networks in the United States and did not name them.
Its site lists palletising and depalletising, case picking and each picking as its main tasks, and notes the launch of next-generation versions of Cassie and Sonny on 16 September 2026 and a 100-robot data factory on 30 April 2026.
Growth and the funding so far
Tutor said its robots are now deployed in almost four times as many facilities as a year earlier, and that nearly a third of the organisations that received robots in the past year were existing customers expanding their use. It did not say how many robots it currently operates. It expects more than 1,000 robots under contract by the end of 2027, all built in the United States. These are company figures.
The company announced a $34m Series A in December 2025, led by Union Square Ventures, according to its website and Robotics 24/7. Neo led the seed round, The Next Web reported. The sources did not give amounts or dates for the seed round.
Who said what
The company was started at MIT's Computer Science and Artificial Intelligence Laboratory by Alon Kosowsky-Sachs and Josh Gruenstein, who is co-founder and chief executive, according to The Next Web.
Gruenstein said: "We can hardly build robots fast enough." Raghu Raghuram, a general partner at Andreessen Horowitz, said continual learning across an expanding range of deployments is the path from specialised capabilities toward more general ones, in a comment that the reports quoted only in part.
The company also published a post titled "Tutor Intelligence and the Next Age of Machines" on 1 November 2026, in which Gruenstein writes about the company's origin and about robot intelligence. Neither report gave revenue or headcount.
