Josh Gruenstein is the co-founder and CEO of Tutor Intelligence, an MIT CSAIL spinout building AI-powered robots that work alongside people in American factories and warehouses. He leases robots by the hour instead of selling them, betting that fleet-scale learning, not bigger algorithms, is what finally puts a robot in every factory. In December 2025 the company raised a $34M Series A led by Union Square Ventures, bringing total funding to roughly $42M.

Rylan Hamilton is the CEO and co-founder of Blue Water Autonomy, a Boston defense-tech company building large, software-defined, uncrewed ships for the U.S. Navy. A Navy surface warfare officer turned robotics entrepreneur, he was an early leader at Kiva Systems (acquired by Amazon for $775M) and co-founded the warehouse-robot maker 6 River Systems (sold to Shopify for $450M). Now he is taking the 'mobile robot' idea back to the ocean - aiming to be the Waymo of the open sea, with a $50M GV-led Series A and a first full-scale autonomous ship slated for the water in 2026.
