Ashton Kutcher has become one of Silicon Valley’s most prominent investors. Over the last decade, Kutcher has made key investments in startups that have changed the everyday lives of people across the world. Uber, Airbnb, Spotify, and Skype are all companies that have been a part of Kutcher’s portfolio. In case you’re keeping score, that means that Kutcher has had a hand in making rides, hotels, music, and communication more accessible for millions of consumers. Though these are privately held corporations, anyone who has found their dream weekend getaway on Airbnb or communicated with an international relative for free on Skype knows how these companies have changed the world for the better.

Kutcher has become a leader in Silicon Valley’s financial class. When asked about how he picks his investments, Kutcher has a simple explanation. He said, “If we can create efficiencies in that which is mundane, then we accelerate our paths to happiness…If you find a way to help people find love, or health or friendship, the dollar will chase that.” Since 2010, Kutcher has been a partner in A-Grade Investments, along with Guy Oseary and Ron Burkle, which has allowed him to expand his already diverse investment portfolio. He and his firm continue to seek out cutting-edge investments that will improve the world and their bottom line.
