Tutor Intelligence has raised a $75 million Series B led by Andreessen Horowitz to expand a factory and warehouse robot service that uses remote human operators when machines need help. The company announced the financing on November 2, The Next Web reported.
Customers pay by the hour or by the pick, without buying equipment upfront or signing long-term contracts. Tutor handles deployment, maintenance and software updates. Its Cassie robot handles cases and stacks or unstacks pallets; the two-armed Sonny targets individual-item handling, including e-commerce fulfillment.
In a September 30 interview with the Association for Advancing Automation, chief executive Josh Gruenstein said companies risk leaving customers with extra work when they pretend robots will never need help. Tutor uses its operators’ interventions as training data, linking work at customer sites to development of its robot models.
The Series B is more than twice the $34 million Series A announced on December 1, 2025. Union Square Ventures, which led that round, and seed backer Neo also joined the new financing. Tutor said total funding has reached $117 million, with the latest capital supporting model training and robot manufacturing and deployment.
Tutor says its robots now work in almost four times as many facilities as a year earlier. Andreessen Horowitz reported that nearly a third of customers receiving machines in the past 12 months were existing customers adding more. The company targets more than 1,000 robots under contract by the end of 2027; its current deployed fleet size was not disclosed.
