Yammer raises $25 million, readies expansion

Published on .

San Francisco—Yammer, the business-oriented social network, has raised $25 million in a third round of financing. The company said it will use the new funds to triple its technical corps to 120 engineers, and grow its sales operation “significantly.” The new funding was led by U.S. Venture Partners.

Unlike Twitter or other customer-facing social networks, Yammer is used for private communications within companies and among designated groups, to coordinate or inform about mutual projects. The company said it has more than 1.5 million corporate users.
