In a report out Tuesday, Fortune's Polina Marinova chronicled the downfall of Kleiner Perkins Caufield & Byers, once a giant-maker of Silicon Valley internet startups. The report details how the firm missed early investments in Facebook, Slack, and Robinhood, and was distracted with unprofitable bets on clean energy. Fortune also reported that longtime firm leader John Doerr, 67, overlooked star growth fund leader Mary Meeker when considering his replacement, instead opting for Mamoon Hamid from Social Capital. Meeker left Kleiner Perkins in September 2018 to start her own growth firm, Bond. Visit Business Insider's homepage for more stories.
