Guttestreker consists of Petter Malterud Grøndahl (b. 1989) and Christoffer Kroge Christensen (b. 1990). Although they have drawn large parts of their lives, various studies and jobs took up large parts of their time after high school. It was not until late autumn 2015 that they found each other and started drawing together. They shared a common interest in philosophy and science and wanted to create images that reflected their opinions about the world and the people who live in it. Since then, they have arranged 5 own exhibitions and exhibited at even more. Among other things, they have arranged two exhibitions at Hells Angels at Alnabru and one at Trevarefabrikken in Lofoten.

Previously, they have done assignments for Oslo Fashion Week, Mercedes, Redbull and Microsoft Norway, to name a few.
