These days, SoftBank founder Masayoshi Son can’t escape WeWork. He can’t escape the headlines revealing his desire for the company to put the brakes on its troubled IPO. He can’t even escape his own friends doubting the value of his nearly $9 billion investment in the company.

So it isn’t a surprise that the topic hung over the swanky, multiple-day conference he threw in Pasadena, California this week for 100 CEOs of SoftBank-backed companies and investors in the Vision Fund, the firm’s tech mega-fund. The event went down at the Langham resort in Pasadena, multiple attendees told Cory Weinberg and me. Musician John Legend performed.
