Brad Schultz has been appointed as the head of the new Moshi TV platform, having spent the past four years controlling digital content at the MoonScoop kids content brand Kabillion.
Schultz aims to make the webite the "go-to destination for safe, fun video entertainment for under 13s."
He said: "I'm thrilled to be on board with such an exciting project. YouTube revolutionised the online video space, now it's time to bring that innovation to the kids' space."
Moshi TV will feature animated Moshi short films, uploads from users and content from third-party producers.
Schultz added: "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. We have loads of ideas up our sleeves."
Michael Acton Smith, CEO of Mind Candy, said: "We're delighted to have Brad heading up this immensely exciting area of the business. 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."
