LONDON — Online fashion marketplace Lyst has appointed Jenny Cossons as head of partnerships, a new post.


Cossons will be responsible for “defining and developing the relationships with the hundreds of fashion brands and retailers that Lyst partners with globally,” the London-based firm said.


Cossons, who was previously group head of brand relations at the Net-a-porter Group, reports to Lyst’s chief executive officer and co-founder Chris Morton.


Before Net-a-porter, Cossons was director of fashion and beauty advertising at Conde Nast U.K.


Her appointment follows Lyst’s new site design, which debuted earlier this month with a focus on editorial content created by Lyst and the retailers and labels it partners with.


Lyst recorded more than $10 million in sales for the labels and stores it partners with in July, and the company said it is on track to grow 400 percent year-on-year in 2014, for the third consecutive year, as reported.
