Yalmie was created by accident. When Mata was in the process of creating a YouTube Channel, Mata wanted a unique username. She originally wanted the username Yamie and Yamie would have been a shortened version of her middle name, but it was taken. She added an "L" in the name and on December 29, 2009, she had officially created Yalmie. Because Yalmie is a name unique to Mata, it became her brand.
