Analysis
Tutor Intelligence Inc. has raised $75 million in a Series B round led by Andreessen Horowitz, with Union Square Ventures and Neo also participating, SiliconANGLE reported on November 2, 2026.
A separate report from Tech Funding News puts the company's total funding at approximately $117 million after the round, consistent with the total it had raised following its prior Series A.
What Tutor Intelligence does
Founded in 2021 by chief executive Josh Gruenstein and co-founder Alon Kosowsky-Sachs out of MIT's Computer Science and Artificial Intelligence Laboratory, Watertown, Massachusetts-based Tutor Intelligence rents AI-powered robots to factories and warehouses rather than selling them outright. Its Cassie robot is a single-armed mobile unit that moves packaged goods between pallets and containers at up to 18 items per minute using a vacuum gripper rated for more than 50 pounds; its newer Sonny robot uses two arms and time-of-flight and stereo cameras to pick and pack items with what the company calls dexterity approaching the human form. Tutor trains its models through imitation: human operators called tutors remotely demonstrate tasks on the robots inside a facility housing more than 100 units, and each completed task becomes new training data. Customers range from family-owned manufacturers to Fortune 50 third-party logistics providers, and the company says the number of facilities running its robots has nearly quadrupled over the past year.
“Neo, which also joined the earlier round, returned to lead or co-invest again in this Series B alongside a16z.”
Tutor Intelligence funding history
Tutor's first outside capital came as a $34 million Series A led by Union Square Ventures, which brought its total funding to $42 million, per SiliconANGLE's December 2025 coverage of that round. Neo, which also joined the earlier round, returned to lead or co-invest again in this Series B alongside a16z. Raised is not valuation here: none of the current reporting discloses a valuation for either round, only the dollar amounts raised.
Who invested in Tutor Intelligence
- Andreessen Horowitz (a16z) -- lead investor on the new $75 million Series B.
- Union Square Ventures -- led the earlier $34 million Series A; also described as a participant in the Series B by Tech Funding News.
- Neo -- participated in both the Series A and this Series B round, per Tech Funding News.
A16z general partner Raghu Raghuram said of the investment, "Tutor's insight is that deployment isn't just the destination for robotics research," according to the company's own announcement on its website.
Warehouse robotics market and competitors
The global warehouse robotics market was valued at $12.52 billion in 2025 and is projected to reach $66.83 billion by 2035, a compound annual growth rate of 18.73%, according to Next Move Strategy Consulting. Tutor's pitch rests on a specific gap in that market: roughly 90% of factories in the United States still operate without robots, per SiliconANGLE's earlier reporting, largely because capital-intensive robot purchases are a hard sell for smaller operators. Tutor's usage-based, no-upfront-cost model is designed to remove that barrier, though no source opened in this reporting names a direct rival running the identical rental pricing model, leaving open whether competitors with larger balance sheets could undercut Tutor on price once the category matures. Gruenstein said in the company's announcement, "We can hardly build robots fast enough," a claim about demand that current reporting has not independently verified against order backlogs or wait times. Our funding tracker tracks robotics and physical-AI startups alongside the software-only AI companies that have dominated 2026 fundraising, a category Tutor's raise helps fill out.
What to watch next
The figure worth tracking next is utilization per facility rather than facility count -- a near-quadrupling in deployments says little if the added robots sit idle much of the week, and that distinction will determine whether Tutor's usage-based pricing actually produces durable revenue.
