Brad Schultz will head up Mind Candy's new LA office, and lead the new Moshi TV platform.
Schultz was previously director of digital media at multi platform children's channel Kabillion. He also founded marketing company Flying Penguin, and launched shows like Hero:108, Rob Dyrdek's Wild Grinders and Chloe's Closet.
"We're delighted to have Brad heading up this immensely exciting area of the business," said CEO Michael Acton Smith.
"We share the same vision, and with his experience and skill set, he's definitely the right man to get Moshi TV off the ground."
Moshi TV will feature Moshi Monster cartoons, user generated content and content from third party partners. The service will launch later this year, with a planned mix of free and premium, paid for content.
"I'm thrilled to be on board with such an exciting project. You Tube revolutionised the online video space, now it's time to bring that innovation to the kids' space," added Schultz.
"Our vision is to change the face of children's content production. We want to be the go-to destination for safe, fun video entertainment for under 13's."
One of Schultz's first moves will be a visit to the MIPCOMJr/MIPCOM event in Cannes, and will be actively looking for content partners for Moshi TV.
"We're looking to work with content producers to help launch cool new brands. We'll also produce all sorts of Moshi content that will further deepen the story behind the characters and the brand."
Mind Candy launched Moshi Monsters in 2008, and the game now has around 50 million users.
