The company, born out of the digital businesses of the Wace Group, offers a wide range of graphic imaging and related services.
As a director of the company and a member of its management team, Hinton's brief is to help build its business with agencies. He will divide his time between the company's London and Chicago offices.
Hinton, 55, a former IPA president, was axed from Bates in November 1999, later settling a legal action against the network for alleged unpaid bonus payments.
The following year he went into business with Tony Douglas, with whom he once shared the chairmanship of DMB&B, to develop advertising on airline tickets.
However, the venture was hit badly by the slump in airline travel and Hinton is known to have talked to major agencies about various roles before opting for Seven.
"As the need increases for agencies to get their messages to market faster, more efficiently and more cheaply, so will the work for groups such as Seven, Hinton said.
M&C Saatchi, St Luke's and TBWA/London are among the agencies already working with the company, whose corporate clients include Kraft, Kellogg, Johnson & Johnson and Procter & Gamble.
