With over 10 years of music business experience, DuFour got his start at the NYC-based marketing/promotion firm Cornerstone Promotion, where he was the editor in chief of the company's music taste-maker focused web property TheTripwire.com. While there, he was also a key member of the company's radio promotion and street marketing teams before leaving in 2007 to form En Prise Entertainment, a partnership with long-time friend, DJ and artist, Chess Hubbard. En Prise began as an event promotion, influencer marketing and artist development company, but soon took over the troubled free print magazine UR Chicago. En Prise re-branded UR, turning it into an online-only property that celebrated the youth-focused indie nightlife culture of Chicago. Over the course of just one year, UR Chicago went from a failing print magazine to a flourishing online property with over 20,000 unique visitors per month, an e-list of over 60,000 opt-in subscribers and a marketing arm that attracted lasting partnerships with brands like Diesel, Adidas, Puma, Tito's Handcrafted Vodka, and Rockstar Games.

As an artist manager, DuFour played an instrumental role in the development of Chicago-based act OFFICE, securing them a three-record, six figure record deal with James Iha's (Smashing Pumpkins) Scratchie Records. He has also developed Chicago-based hip hop act Hollywood Holt, securing him a deal with taste-maker indie hip hop label Chocolate Industries. DuFour continues to develop one to two projects per year, most recently Chicago-based electro pop duo Moneypenny and teen rocker Purple Apple.
