iPhone and Android gig-discovery app WillCall has been kicking around for a while now: it first launched on iPhone back in February 2012. This week it announced a $1.2m funding round though, with Napster/Facebook/Spotify veteran Sean Parker one of its new investors, alongside other figures from the music industry. For now, WillCall provides San Francisco and New York music fans with a list of upcoming gigs, selling tickets in-app, with artists able to promote their merchandise and accept (money) tips from fans using the app. The startup has raised $2.1m in total so far, and plans to expand to Los Angeles in the near future. Much will depend now on how many artists WillCall manages to sign up, and how quickly it can expand in the face of stern competition from established live-music discovery services like Songkick and Bandsintown, which could forge their own partnerships to do more around ticketing and merchandise. Parker’s involvement could be fun though: we wonder if there’s scope for an interesting Spotify integration if and when WillCall goes more global.
