Well, the first edit by the wikia bot "default" on the homepage is always to be set on the day of the founding of any wiki. No matter what. This means the wiki was founded in September 25, 2006. However, the first edit on the homepage was by V-Rex (not the founder) on January 10, 2007. This doesn't help but we know that the wiki was founded that early.

However, way early than September 2006 A user Rsnail made the edit to make the page Club Penguin on March 15, 2006. I am 99% sure that Rsnail is the founder.
