Retargeting data, the quiet multiplier
Every person who watches a clip, taps a link, visits a show page, or pre-saves becomes an audience we can reach again. The next single, the tour stop, the merch drop, and the holiday push all start warm. Warm audiences typically convert at a fraction of the cost of cold ones, so every Wave makes the next one cheaper.
Across a roster, those pools become a cross-artist asset: fans of one lounge legend are the most likely fans of the next.
Ad pools live inside each ad platform and cannot be exported. The fan list is the part the artist owns outright, which is why the engine captures both.
