“My goal is to be the world’s least-powerful CEO,” declares Ilkka Paananen, the cofounder and CEO of Helsinki’s $2 billion mobile game company, Supercell. Paananen believes that the secret to producing hits is to attract highly talented employees, give them ridiculously ambitious targets, and then let them loose to decide among themselves what products to make. With billion-dollar blockbusters such as Clash of Clans, Hay Day, and Clash Royale, the company has proved that the strategy of not disturbing people with too much leadership can work magic.
