His move comes as Blink looks to expand its roster of directors by as many as five. He will also work as a hands-on producer, both on commercials and at its music video and animation arms, Colonel Blimp and Blinkink.
The Blink managing director, James Studholme, said: "Ed's call came at a moment when I felt we needed more executive firepower to keep on developing and he completely fits the bill. We want to build and refresh the advertising core of the company."
Sayer said: "I've always had my eye on Blink. I like its sense of personality, which I believe stems from James' passion and sense of caring. On deciding to close Godman, James was the first person I wanted to call."
Godman ceased trading in March after a decade of commercials production.
Sayers cited pressure on margins and prices as reasons for the company's closure.
Blink has a roster that includes the directors Dougal Wilson and John Birkin and the directorial teams Lynn Fox and Pleix. Wilson has just directed the "ride" film for Orange through Fallon.
