Maarten Janssens first came to notice at age 15 when he won a comic talent competition organized by Het Stripschap and the Veronica guide. After having drawn for his highschool newspaper and some club magazines, Maarten got his first official assignment from a printer in Sittard. Together with Wout Paulussen, he made the comic book 'Funs en Finke in: Sittard 750 Jaar Stad' in 1993. In the following years, Maarten drew for magazines like Noppes, and he made the illustrations and title comic of the juvenile animal magazine Banjer, with scripts by Pascal Oost.
Maarten now works as an illustrator/concept artist, making concept designs and art direction guides for art studios. He has worked for the Dutch Disney publications of Sanoma Uitgevers, where he illustrated covers for the Donald Duck weekly and Donald Duck Extra, editorial sections like the Woodchuck's Page and World Treasures, as well as an occasional letterbox and contest comic. He has also designed the original official Donald Duck website. He was one of the artists working on the Dutch animation series 'Kika en Bob', and now gains fame through his paperkits for little paper creatures through 3eyedbear.com.
