SoftBank launched its first, $100 billion Vision Fund in 2017. Just last month, the Japanese conglomerate led by Masayoshi Son said the fund had delivered record profits for the quarter. But there have been some big failures too. The modular-construction startup Katerra filed for bankruptcy last week. SoftBank had invested more than $2 billion in the company. Katerra had borrowed money from Greensill Capital, which also received about $2 billion of SoftBank money. Greensill also collapsed earlier this year. That, of course, follows the WeWork debacle a couple of years ago. Marketplace’s Amy Scott speaks with Sarah Kunst, managing director of the venture firm Cleo Capital. She said SoftBank’s strategy has been to make huge bets on relatively unproven companies.
