Elon Musk, Mark Zuckerberg, and Ashton Kutcher invest in Vicarious

Elon Musk made the electric car cool. Mark Zuckerberg created Facebook. Ashton Kutcher portrayed Apple founder Steve Jobs in a movie. Now, the three are joining in a $40 million investment in Vicarious FPC, a secretive artificial-intelligence company. The funding round, the second major infusion of capital for the company in two years, is the latest sign of life in artificial intelligence. Last month, Google acquired another AI company called Deep Mind for $400 million.

It has been a big year for artificial intelligence. Google bought DeepMind in January for $400 million and, now, a group of tech elites and venture capital firms have awarded $40 million to Vicarious. Venture capital firm Formation 8 led the round, the Wall Street Journal reported Friday. It was joined by Tesla and SpaceX CEO Elon Musk, Facebook CEO Mark Zuckerberg and actor Ashton Kutcher. Re/code reports that Box CEO Aaron Levie, incoming Y Combinator president Sam Altman, Braintree founder Bryan Johnson, Khosla Ventures, Good Ventures Foundation, Felicis Ventures, Initialized Capital, Open Field Capital, Zarco Investment Group, Metaplanet Holdings and Founders Fund were also involved. Vicarious received $15 million in a first round in 2012.
