After 27 years at the tech giant, Dean said that he was leaving to found Discovery Loop, a public benefit corporation focused on automating machine learning, science, and engineering discoveries. Google will take a stake in the business.

He will be joined by fellow Google veteran Sanjay Ghemawat, who was instrumental to the development of products like TensorFlow, Bigtable, and Spanner.
