Slicethepie has taken a big step forwards via a deal with social network Bebo that will promote its artist-financing model to the latter’s community. Bebo users will be able to review tracks by new artists on Slicethepie, as well as investing in their favourites. They’ll get paid for every review they write. Slicethepie could do this simply by launching an application on Bebo (or Facebook, or MySpace…) so what’s the advantage of a fully-fledged partnership? Presumably better visibility on the Bebo website. However, there’s more to it. Slicethepie reckons that one artist a month will be financed as a result of the deal, with Bebo providing a “valuable promotional package” to each of them, although exact details haven’t been announced.It all kicks off next month.
