Graham Younger, the head of SAP’s SuccessFactors cloud HR software unit, is leaving the company to become the head of field operations for enterprise cloud storage/file-sharing upstart Box. The move comes less than a month after Quartz reported Box, which SAP’s VC arm has invested in, has confidentially filed for an IPO. SAP bought SuccessFactors for $3.4B in 2012. Lars Dalgaard, SuccessFactors’s CEO at the time of the acquisition, left SAP last year.
