After Boies, Schiller & Flexner‘s revenues rose 18 percent to $295 million in 2008, partners David Stone and Robert Magnanini made a surprising choice. Despite the firm’s success, they left to start Stone & Magnanini, a six-lawyer firm in Short Hills, N.J. Stone, 51, hopes that they will continue to score clients, even without the Boies name on the door.

"The myth that you have to hire a Cravath or a Sullivan is dissipating," says Stone, who made the move, in part, to avoid potential conflicts between Boies’ corporate clients and the False Claims Act whistleblowers he represents.
