Investors in Son's Vision Fund 1 include Apple, Qualcomm, Foxconn, the family office of billionaire Larry Ellison and Saudi Arabia's sovereign fund. The Vision Funds have invested in over 400 companies, including ride-share firm Grab, Korean e-commerce leader Coupang and India's food-delivery platform Swiggy.
