EXCLUSIVE: Julie Darmody and Christie Smith, two senior managers at Mosaic, are peeling off to start their own business. They just announced this internally. It is a jolt to Jimmy Miller’s management/production company, but I hear there is enough history there that they are dealing with it in an amicable fashion. Darmody has been with the company 22 years, and Smith about eight years. Among the clients they rep who’ll be part of their new company are Jurassic World star Chris Pratt; the Lonely Island team of Andy Samberg, Akiva Schaffer & Jorma Taccone; Nick Kroll; and Comedy Central host Daniel Tosh. I’m waiting for more details on the exit and the new venture and will furnish them shortly.
