Six years inside LinkedIn. $75M in ad spend managed. $700M in pipeline generated for HP, Expedia, Thomson Reuters and the London Stock Exchange. At Kleos, that operating knowledge is what every client gets  specifically, how buying committees form preferences before the sales conversation starts. The same material I teach on the MBA programme at IE Business School.
