Digital distribution firm TuneCore has snapped up US mobile startup DropKloud. The latter was unveiled in beta earlier this year as a way for musicians and brands to “drop” digital stuff – tracks included – at real-world locations for fans to find using their smartphones. TuneCore says that DropKloud will launch commercially in spring 2015, but now exclusively for its artist customers. Meanwhile, the Boston-based startup’s founders will also be working within a new “TuneCore innovation lab” in their home city. TuneCore boss Scott Ackerman promised that the new lab will be “committed to creating cutting edge tools for our artist entrepreneurs”.
