US startup Chirpify has announced a $1.3m Series A funding round for its Twitter commerce platform, and launched a new service specifically for musicians. The latter is called Twitter Commerce for Digital Content, and aims to help artists sell music and gig tickets through their Twitter accounts. It works by artists uploading songs to their Chirpify account then tweeting the links, although fans have to a.) have a PayPal account and b.) connect it to Twitter to buy – once that’s done, they can buy the content simply by replying to the artist’s tweet. It’s delivered via email and/or direct message. “People already use Twitter to follow the brands, musicians and others they care about, so why can’t they get the latest product or hot new song right through Twitter? Now they can,” says CEO Chris Teso. Stay tuned for a more detailed interview and hands-on impressions of Chirpify in next week’s Sandbox report.
