We’ve been writing regularly about big media companies running startup accelerators and incubators in recent months, but what about brands? Red Bull unveiled its Amplifier accelerator on Friday: a programme focused on music startups. It won’t be investing money, but rather promising a “creative partnership” for selected startups whose aim is “engaging them with Red Bull’s networks and enhancing its existing music properties with innovative technology in the process”. Applications are open now for the first Amplifier class, with a deadline of 22 April for entries. Red Bull says it’s looking for early-stage independent startups with products “developed enough to go to market or be piloted with large numbers of users” – although it’s also welcoming people with just “an amazing hack that needs nurturing”. SoundCloud’s Dave Haynes – a man who knows a thing or two about amazing hacks through his work on Music Hack Day – is on board as a judge.
