Former Whistles chief financial officer Phil Mickler has joined Jack Wills in the same role, replacing Ian Johnson, who has left to seek other opportunities.
Johnson joined Jack Wills in August 2014 and decided to resign after the company decided not to progress with an IPO for the foreseeable future.
Mickler was previously finance director at Diesel from March 2008 to January 2010 and finance controller at Topshop from September 2005 to February 2008. He spent almost five years in finance roles at Ocado.
Chief marketing officer Emma Sheller and global business development director Sanjay Sharma, who both joined in May 2013, have also left the firm to pursue new opportunities.
Jack Wills’ founder Peter Williams returned to the business as chief executive in August last year and his predecessor, Wendy Becker, stepped down.
Mark Wright, formerly head of trading for UK ecommerce for Marks & Spencer, joined the company as managing director of ecommerce and Sophie Neary became chief customer officer in the second part of last year.
Neary, who was previously working at Jack Wills on an interim basis, has worked with retailers including Tesco and Asda on a consultancy basis in the past.
Tim Allinson, who was previously UK logistics director at Dixons, also became global supply chain director.
Williams said: “I am delighted that Jack Wills has attracted such a high-calibre new team as we prepare for further expansion in 2016.
“Phil, Mark, Sophie and Tim are highly experienced retail professionals with vital skills and they will provide the backbone for the group as it continues to grow. I would like to welcome them all. At the same time I would like to thank Ian, Emma and Sanjay for their contribution to Jack Wills and wish them every success in their future careers.”
