H&M said the eight-year-old brand “has experienced  strong growth through its simple and secure buying and selling service for second-hand items”. It has launched “multiple innovations to make it even more convenient for customers to buy and sell secondhand, and now takes one step further by releasing an app”.

The app will enable customers to shop its 1.6 million items “in a seamless experience, making it easier than ever to buy secondhand”.

Sellpy is majority owned by H&M after it began a strategic partnership in 2015 through investment arm H&M Co: Lab.

Its co-founder and CEO Michael Arnör said: “In order to empower everyone to live circular, we want to be able to meet our customers wherever they are. In our strivings to provide a seamless and friction free shopping experience, we are happy to offer this new touchpoint, where customers in all of our 24 markets can update their wardrobes and homes in a more sustainable way.”
