The head of one of Europe’s largest online retail groups plans to step down.

Sweden-based Qliro Group AB, No. 44 in the Internet Retailer 2015 Europe 500, announced that CEO and president Paul Fischbein will leave the company, which sells a range of products from books and videos to women’s apparel to household appliances.

Fischbein will stay on until Qliro finds a replacement. Fischbein, who was previously CEO of household appliances e-retailer Tretti, has served as CEO of Qliro since November 2011, when Tretti was acquired by Qliro Group.

“Paul Fischbein has been a significant contributor to Qliro Group’s successful transformation and rapid growth, and under Paul’s leadership a stable foundation has been laid for the continued development of the Group and its subsidiaries,” Qliro Group board chairman Lars-Johan Jarnheimer said.

Top500Guide.com data shows that Qliro Group had steady online sales growth under Fischbein’s leadership. Qliro Group grew sales from 382.0 million euros ($427 million) in 2012, his first full-year at the helm, to 535.6 million euros in 2014 ($598.6 million) in 2014, annual growth of 11.92%.

In its 2014 annual report, Qliro Group says 4 million customers made 8.5 million purchases across all of its online properties.
