Superfans-focused startup Stationhead is merging with another music-tech firm, Mellomanic. Mellomanic is the company formerly known as We Are Giant, which built a platform for artists to hold listening parties and online events. The merger, backed by new investment from UMG and Sterling Partners, will see Stationhead co-founder and CEO Ryan Star shift to chief creative officer, with Mellomanic boss David Rappaport taking over as CEO. “Through live listening parties that have already driven billions of streams on premium streaming services, we’ve demonstrated the commercial power of fandom at scale,” added Star. Besides taking a stake in Stationhead – the merged entity is keeping that name – UMG has also signed a commercial agreement to use its tech.
