Bill Jemas, former publisher at Marvel Comics, is now involved with Valiant Entertainment.
Rich Johnston at bleeding cool made the announcement of Jemas’s involvement. The announcement itself doesn’t say much about the capacity of his involvement, so that is still up for speculation. Whether he is an employee, a shareholder, an adviser, or any other capacity is not publicly known.
Jemas is known for being the publisher at Marvel Comics in 2000, the year that turned around Marvel from the brink of bankruptcy to the publishing success it is now. The big projects that were started during his tenure were Marvel Knights and the Ultimate Universe, both were very popular and successful.
He seems like the kind of guy that is willing to take risks and try different stuff, which is probably a good thing for Valiant.
