Operating under the name of Rebel Monkey, the new studio has been co-founded by Margaret Wallace. She formerly helped to set up and run San Francisco-based casual games studio Skunk Studios and will take on the role of CEO at RM.
Wallace has established the company together with Nicholas Fortugno, whose design credits include Diner Dash and Plantasia.
"Rebel Monkey came about as a meeting of like-minds - with a common goal of taking casual games to the next level," said Wallace.
"Both Nicholas Fortugno and I have been involved in casual games since the beginning, so we are bringing a lot of experience to the table."
Rebel Monkey has yet to announce details of its first project.
