Yammer Raises $5 Million For Workgroup Micro-Messaging

Fifty thousand dollars will only go so far. As the winner of last year's TechCrunch50 , that's how much workgroup micro-messaging service Yammer received in prize money. But Yammer has now raised a $5 million series A financing from the Founders Fund and Charles River Ventures, according to founder David Sacks. Yammer is a spinoff from genealogy site Geni, which also just received another $5 million from the same investors in a series C financing.
