Tutor Intelligence has raised $75 million in Series B funding led by Andreessen Horowitz, as the Massachusetts robotics company expands deployments of AI-powered robots across U.S. industrial facilities. Union Square Ventures and Neo also participated in the round, according to co-founder and chief executive Josh Gruenstein, who announced the financing on November 2.
The investment will support robot manufacturing, further development of the company’s foundation models and deployments in industrial environments. Tutor builds semi-humanoid robotic systems designed to handle material movement and other repetitive work in warehouses and factories. Its approach combines autonomous robot policies with human operators, known internally as tutors, who can guide machines through tasks and help generate training data from real operations.
Gruenstein said Tutor’s robots now operate at nearly four times as many customer sites as a year earlier. Nearly one-third of its deployments this year have been to returning customers, he added, and the company expects to have more than 1,000 robots under contract by the end of 2027. Those figures are company-reported, and the contract target is not a count of robots currently deployed.
The Series B follows Tutor’s $34 million Series A announced in December 2025, which was led by Union Square Ventures and co-led by Fundomo. Since then, Tutor has expanded its hardware and AI development efforts. In April, it introduced Data Factory 1, a fleet of 100 robots intended to collect physical-world training data. In September, it unveiled the next generation of its Cassie and Sonny robot platforms for supply-chain operations.
Tutor’s development strategy relies on putting robots into production environments while using human intervention and operational data to improve the models controlling them. The new capital gives the company additional resources to build and deploy that hardware while training the systems intended to make it more capable over time.
The company has not disclosed a valuation for the Series B in Gruenstein’s announcement.
