About bloomerang

Eco-conscious, ideas-driven."

bloomerang isn't the typical two guys and a garage start-up. Actually, we would really like to have a garage!

We are based in Singapore and, like most start-ups, we are the product of happenstance colliding with passion. Zhiwen, 27, combined his experience in the paper products supplies industry with a desire to run a business that gives back to society. So he designed bloomerHang himself and started bloomerang in June 2008. Zhiwen happily found himself with a business partner three months later when his junior college classmate Joon Ian decided to leave his journalism job in Shanghai to join Zhiwen in Singapore. (bloomerang's note: Joon Ian has since left us for London to pursue his Master's - we wish him well!)

We've heard bloomerang labeled a 'social enterprise' and an 'eco business' —  but one thing's for sure: We want our business to do its bit for society, however small it may be.

Our first product is bloomerHang, a new environmentally friendly advertising platform. Read the FAQ

This Is No Ordinary Hanger

"For advertisers hung up over new ways to push products, two young entrepreneurs may have found an answer in the humble clothes hanger. Known as bloomerHang, the paper hangers created by the duo provide space for marketers to showcase their products ... 'We think of bloomerHang as a hybrid of traditional out-of-home advertising and direct mail, except better,' Mr Wong, 27, told BT. 'For a start, unlike direct mail, we are invited into your home through our targeted distribution network. And bloomerHang is a fully functional garment hanger, so you have a reason to be exposed to it and to keep it in your home. That's a point an out-of-home billboard cannot claim.'"— Jamie Lee

Allen Tan's beautiful picture of bloomerHang was fortunately picked for the front page of the Business Times' print edition, to lead in to Jamie's story on us. Thanks, Allen!
