Top Amazon exec tasked with integrating Whole Foods leaves company.

Greg Greeley, head of Amazon’s Prime program, announced he would leave the company after 18 years on Monday.

“It has been an amazing and inspirational experience, but the time has come for me take on a different challenge,” he wrote on LinkedIn.

This news comes just weeks after Greeley took on more responsibilities with Whole Foods, which Amazon acquired in 2017. “We are working with the team at Whole Foods Market to deliver tremendous value for Prime members at Whole Foods Market and Greg will be facilitating that effort, among other things,” an Amazon spokesperson told Yahoo Finance in an email in late February.
