Theodor Mauritz Forselius (born March 23, 1995), known as "Tedde", is a Swedish Internet entrepreneur and programmer. He is the co-founder and head of design of Everipedia, which he created with Sam Kazemian, Mahbod Moghadam and Travis Moore in 2015. 
Theodor and Sam Kazemian originally met through a mutual acquaintance in 2013. But it wasn't until the summer of 2014, when Theodor was visiting Sam Kazemian at UCLA., that the two began discussing the original idea behind what would later become Everipedia. A few months later during the fall, the two decided to officially start working on the project and Theodor moved to Los Angeles, California to focus on Everipedia full-time. During the spring of 2015, Mahbod Moghadam and Travis Moore joined as founders and together they raised a seed investment from Mucker Capital.
