Founded a decade ago, Team Whistle is a survivor. It sprang to life as a wave of multichannel networks that filled the need of aggregating YouTube properties to make buying easier. The biggest problem of the MCN model is that it takes a difficult business model (advertising) and makes it even more difficult because you’re taking a cut of a cut, after YouTube gets its taste. Most MCNs fizzled.
Whistle shifted its focus to building its own properties, producing franchises like “No Days Off,” a series following incredibly focused child athletes. It still reps other properties, like Dude Perfect. It complemented that with an agency business that relies on the distribution and cachet of the original programming.  Whistle is part publisher, part agency.
