Josh Gruenstein

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.
