Dan Wright, CEO of artificial-intelligence software pioneer DataRobot, has resigned less than a year and a half after ascending to the position, according to a departure memo viewed by The Information. Wright is leaving amid tepid revenue growth and following employee uproar over the revelation, first reported by The Information, that he and other senior executives quietly sold $32 million worth of stock last year when the company’s private valuation peaked at $6.3 billion, while the other 1,200 or so employees didn’t get the same opportunity.

DataRobot President and Chief Operating Officer Debanjan Saha, a former Google Cloud executive who joined in February, is taking over for Wright on an interim basis, according to the email.
