In spring 2012, Yammer was on track to become a highly successful standalone company. Yammer was a leading Enterprise Social Network (ESN), providing companies a private social network in which employees could collaborate securely and efficiently.

David Sacks, CEO of Yammer, debated the challenges and opportunities related to competition, product, and culture as he thought about the offer on the table.
