Catalogtree is a multidisciplinary design studio based in Arnhem (NL). It was founded in 2001 by Daniel Gross and Joris Maltha who met at Werkplaats Typografie. Nina Bender was part of studio from 2011 until 2020. The studio works continuously on commissioned and self initiated projects. Highly interested in self-organising systems they believe in 'Form Equals Behaviour'. Experimental tool-making, programming, typography and the visualization of quantitative data are part of their daily routine.

Recent endeavours include recycling pink plastic toys to create a way-finding system, turning a pocket calculator into a metal detector and designing a GIS route to the best spot for dropping a seventeen ton marble rock into the Mediterranean. Daniel Gross and Joris Maltha teach at ArtEZ Institute of the Arts in Arnhem (NL) and have taught and lectured widely. The work of Catalogtree is in the collection of the Cooper Hewitt, Smithsonian Museum of Design (NYC, USA), The Archive of Het Nieuwe Instituut (Rotterdam, NL) and the Museum of Design Zurich (Zurich, CH).
