Former Amp’d Mobile founder Peter Adderton has resurfaced on the entrepreneurial circuit via a new venture he’s launching today in partnership with the William Morris Agency.

Mr. Adderton and William Morris said they have formed Agency 3.0, an agency that will focus on working with companies, content providers and advertisers to develop digital strategies.

“There’s a whole new world in the marketing, distribution and monetization of digital media, with unique demands for new approaches to both design and implementation,” said William Morris Chairman-CEO Jim Wiatt in a statement Wednesday.

Mr. Adderton, whose last venture, Amp’d Mobile, filed for bankruptcy, will be chairman and CEO of Agency 3.0. He will focus on mobile and wireless clients.

Agency 3.0 is located on site at William Morris’ Beverly Hills headquarters.
