Guillaume Singelin was born in Rennes, France, and grew up inspired to draw by Disney comics and manga. While studying graphic design at EPSAA, he was approached by writer Antoine Ozanam (KLAW, Temudjin) to work on a retelling of the David and Goliath story in King David, revised to be a contemporary mafia tale. But comics weren’t what he originally imagined doing, so he joined the animation team at Ankama to work on the feature film MUTAFUKAZ, based on the Label 619 comic series by Label founder Run. It was during this time Singelin dreamed up The Grocery, a madcap combination of cartoonish characters in a gritty urban setting much like The Wire. That unique recipe found fans, and he soon began contributing more and more work to the growing portfolio of Label 619, including stories for Doggybags, Midnight Tales, and the MFKZ spinoff Loba Loca. His first full-length graphic novel to be published in English was the dense postwar drama PTSD, which not only refined his unique balance of cartoony characters in gritty situations but cemented his reputation for thoughtful and multilayered storytelling. His manga-inspired character designs pop out of realistically rendered environments to come to life. From that experience and exposure, he was tapped by DC to create a handful of Batman backup stories (in Urban Legends and DC Vampires). Aside from comics, he continues to work in other fields, including video games, producing illustration, and character design for titles such as the celebrated multi-platform game Citizen Sleeper.
