San Francisco: BranchOut, a professional networking application on Facebook, has closed $25 million in series C round of funding leb by Mayfield Fund, along with existing investors Accel Partners, Norwest Venture Partners and Redpoint Ventures. This brings the total fund raised by the company to $49 million. The fund will be used to expand its San Francisco based team of 45 people.

“We power the professional profile for the Facebook generation. Online networking is not just for managers and executives. New college graduates, retail workers, nurses, software engineers and military veterans re-entering the workforce can all benefit substantially from having strong professional profiles on Facebook,” said Rick Marini, Founder and CEO, BranchOut.

Launched in July 2010 as a free application that allows users to create a professional profile on Facebook, the company has grown into a larger professional networking application on Facebook with more than 25 million registered users and over 400 million professional profiles. BranchOut offers a suite of recruiting products for both job seekers and recruiters.

“It is unprecedented to see this type of growth, which makes BranchOut one of the most used apps on Facebook. I am excited by the opportunity BranchOut has to introduce the notion of a professional social network to the 90 percent of the population that is not on LinedIn,” said Tim Chang, Managing Director, Mayfield Fund.

Chang joins BranchOut’s Board of Directors, which also includes Marini, Kevin Efrusy from Accel Partners, Geoff Young of Redpoint Ventures, and Co-Founder of Ooga Labs, Stan Chudnovsky.
