About Us

Our story

Come in and see our World of Books

Get behind the scenes with us and explore the re-use revolution

Our story

It all began when a group of book loving entrepreneurs noticed a bag of books in charity shop bin destined for landfill. Our founders rescued them on the spot, determined to give them a second life.

Over the last two decades, we have grown from a start-up into a leading global seller of quality used books and pioneers in re-use and recycling. Our inventory has grown to over seven million items in stock and we sell a book somewhere in the world every two seconds.

Business for good

We are a circular economy, for-profit business founded on the ethos to do good, help charities and make a positive impact.

Our business model is designed to protect the planet by enabling more goods to be reused. We are committed to creating positive impact for communities, the environment and our people in an effort to achieve a more sustainable future.

In 2018, we were awarded B Corporation® (B Corps™) status – a businesses that meet the highest standards of verified social and environmental performance, public transparency and legal accountability to balance profit and purpose. In short, we care about people and the planet.
