Notonthehighstreet chief executive Simon Belsham has stepped down from his role at the online retailer with immediate effect.
According to Retail Week, Belsham is departing for personal reasons.
He had been in the role since May 2015, when the marketplace hired him from Tesco, and has been responsible for recording growing sales and reducing losses.
Belsham also secured £21 million venture capital funding.
“It‘s been a privilege to have led the business during an important transition period for the company from the founders to the new management team and I‘m proud of the progress we have made,” he said.
Chairman Darren Shapland will lead the online marketplace until Belsham‘s successor is appointed, with the help of chief commercial partner Ella d‘Amato and chief financial officer David Phillips.
Belsham‘s resignation comes after chief technology officer Hugh Fahy recently departed the business only a year after joining it from Net-a-Porter.
