Tutor Intelligence raises $75M Series B led by a16z for its Sonny and Cassie robot workers

Tutor Intelligence, a robotics company in Watertown, Massachusetts, announced a $75 million Series B on November 2, 2026, led by Andreessen Horowitz. Union Square Ventures and Neo, which led the company's Series A and seed rounds, also participated. Tutor says the round brings its total capital raised to $117 million.

Tutor deploys two robot workers, Sonny and Cassie, into U.S. manufacturing and logistics sites, where they handle everyday goods such as breakfast cereal, snacks, candy, cosmetics, home goods and toys. Remote human operators the company calls "tutors" guide the robots, and Tutor says every task the robots complete generates data that trains its robot foundation models. The company says the new money goes to model training and to building and deploying more robots, all built in and deployed from the United States.

Per the company, its robots are now working in almost four times as many facilities as a year ago, and it is on track to have more than 1,000 robots under contract by the end of 2027. Lead investor a16z says nearly a third of customers who received Tutor robots in the past 12 months were existing customers installing more, and that implementation can take as little as 8 hours.

Why it matters

Tutor puts robots to work before they are fully autonomous, with remote operators filling the gaps, an approach a16z calls novel. It also sells robot work by the hour or by the pick, with no upfront purchase or long-term contract. The 1,000-robot figure is the company's own target for 2027.
