AdExchanger reports that Index Exchange hired Drew Bradstock to serve as SVP, product. Bradstock comes to Index Exchange from Google where he spent the last five years as group product manager of Google’s Ad Exchange. One area of focus for Index Exchange is header bidding, and Bradstock's mission will be to develop a forecasting tool that enables publishers to see the true value of their inventory, along with the exchanges where they will get the best price. A tall order.
