Tensions had been growing between Salesforce Inc.’s
CRM,
co-Chief Executives Marc Benioff and Bret Taylor over their responsibilities and how the business was run for months before the business-software provider said last week that Taylor would exit the role, people familiar with the executives said.
Benioff, who is also co-founder, became frustrated about how Taylor was spending his time, the people said. Among his concerns were whether Taylor was spending too much time in a new role as Twitter Inc.’s chairman, too much time with other CEOs and customers and not enough time on Salesforce product and engineering, the people said.
