This year OpenLab is to launch a curated music service, digital download store, a subscription streaming service and a social network. In addition, over the next two years Miles will open a creative space in Ibiza for artists to collaborate. Work on this has already started.
Miles, who found fame with the dance track Children 20 years ago, founded OpenLab in 2013. The service also includes a webcast.
Miles said: "We needed an agency that genuinely understands the music business, as that’s our roots, but is forward-looking enough to help us on our journey into the future.
"Zeitgeist totally fits the bill. You can see that same approach in the diversity of clients it represents and the imaginative, full service approach it takes to promoting them."
Zeitgeist, which was founded by Jamie Stockwood and Paul Kennedy, handles PR for events such as the Reading and Leeds Festival and brands that have associations with music including Dr Martens, Fred Perry and Jagermeister.
