Forum
Forum is a prediction market platform with a simple, dangerous premise — you can bet on anything. Keystone developed a three-spot spec campaign built around that idea, each one finding a different flavor of human irrationality to hang it on: a viral moment, a student film argument, and a founder who invested in himself a little too literally. The spots blend gen-Z humor with clean holographic UI and a deadpan comedic sensibility that lets the product land without ever feeling forced. Across all three, the creative challenge was the same — make an absurd product feel completely intuitive. We think we nailed it.
