When Octagon launched its media rights consulting business last August, it focused on two areas where it could stand out in a crowded market. It wanted to use Octagon’s global reach to attract clients around the world. It currently has clients on five continents. And it wanted to set up an advisory board of sports business veterans who could set strategy. This week, Octagon started to fill out that board with Lydia Murphy-Stephans and Nic Coward taking the first two seats.
