Yammer began as an internal communication tool built for Geni by David O. Sacks and Adam Pisoni. After six months of use inside the company, Sacks showcased the product at TechCrunch50, where Yammer won the event’s top prize — a launch that propelled it into becoming an independent enterprise communication platform.

In 2009, Yammer rolled out its first major redesign, adding user profiles, group photos, improved following suggestions, and YammerFox, a Firefox extension that notified users of new messages. These features helped establish Yammer as an early leader in enterprise social networking.
