This is Andrew "Boz" Bosworth's strategy memo on how FB should approach ads. Boz is a personal friend of Sriram and ex-colleague and this memo, sent in December 2012, showcases Bosworth's strategy skills.

But in 2013, after a key meeting of Facebook's top ad tech execs with COO Sheryl Sandberg, a decision was taken that would severely limit FBX's future.

In June 2012, Facebook launched FBX, an ad exchange that allowed advertisers to buy retargeted desktop ads using third-party tools like Criteo and AppNexus. The idea was to revolutionize online marketing and a chance to compete with google , which earns $10 billion from the Americas alone.
