The net worth of Zoom’s chief financial officer has jumped by $160 million since last year’s list, thanks largely to several welltimed stock sales as shares of the videoconferencing firm briefly soared above the $400 mark in September. She also joined the board of Utah-based cloud computing outfit Qualtrics in February after it was spun off by German software giant SAP.
