The new privately funded company will be administered globally by Kobalt Music and run by PledgeMusic managing director Malcolm Dunbar.
Dunbar said the organisation, which claims to be the first publishing company set up by a direct-to-fan platform, will sit apart from its sister company - operating in the same way as any other independent publisher, rather than replicating PledgeMusic's fundraising model.
Already PledgeMusic Publishing has signed its first act, Brighton-based singer songwriter Sophie Madeleine, who funded the release of her debut album through PledgeMusic.
And Dunbar said the company would be able to cherry pick artists from PledgeMusic to sign to its publishing arm.
"We will also sign acts who haven't worked with Pledge before," he said. "This is simply a logical extension to everything that PledgeMusic has carried out so far, as we are now working with so many great artists we are in a unique position to discover new talent. It therefore makes complete sense for PledgeMusic to offer a music publishing option to those artists that we feel might benefit from the service."
PledgeMusic Publishing will focus both on securing sync placements for its roster and developing song writing talent and Dunbar added the new business would provide an extra income stream for his company.
"The industry is changing at such a dramatic rate that we have to find new ways of keeping abreast of this. Not all artists nowadays want to sign to a major company and we are here to offer those acts an alternative option."
