Well we are really 4 french guys, we are located in Paris in a small office. This is not a wordpress, but a prestashop and the theme is not generic. And the stuff that is innovative is that all the products are created by the community using the studio (

Have a look at
http://www.stickaz.com/en/info for more infos about the Stickaz concept.
Tell me if you find similar businesses (appart from sites that let's you decline an image on mugs or t-shirts). Hope you look at it with a different angle :)
PS: we know puxxle, we existed before them and there's no user generated content on puxxle.
