Amazon e-commerce platform chief departs

|By:, SA News Editor

Brian Valentine, the Amazon (AMZN) SVP in charge of the company's e-commerce platform, is leaving after nearly eight years with the company. Amazon says the teams managed by Valentine will now report to other execs.

Valentine has presided over an e-commerce tech infrastructure that now handles millions of orders from third-party merchants (responsible for 40% of Q3 paid units), in addition to Amazon itself. Amazon's big investments in this infrastructure have contributed to its steady share gains against eBay and other merchant platforms.

As GeekWire observes, the fact Valentine was once in charge of Windows engineering for Microsoft might fuel speculation he's being considered to replace Steve Ballmer. However, his name hasn't appeared in any of the numerous reports about Microsoft's CEO search.
