Facebook platform companies Shoutlet, Unified, Identified raise combined $50M

Social marketing platforms Shoutlet and Unified, as well as Facebook-based career site Identified, announced new funding rounds this week totaling $50 million.

Although Facebook’s own stock has performed weaker than expected following an initial public offering, there seems to be confidence for other companies building on the platform. These new investments and recent acquisitions of Buddy Media and Vitrue suggest the Facebook ecosystem is thriving despite the social network’s own battering on Wall Street.

Social media management software provider Shoutlet raised $15 million in a Series C. Shoutlet’s platform helps marketers make posts, launch applications and maintain customer profiles across networks like Facebook. The latest round from FTV Capital brings Shoutlet’s total funding to $24.2 million in outside investment. The company says it plans to use the funding to further build its product, strategic partner network and internal team.

Social ad platform Unified picked up $14 million — $10 million in a Series A round from Advance Publications and a $4 million debt facility from Silicon Valley Bank. The company’s Social Operating Platform helps brands and agencies manage paid media campaigns across Facebook and other networks. Operating in stealth mode since April 2011, Unified launched publicly in January.

Identified, a professional networking site that users connect with their Facebook profiles, raised $21 million in a Series B round of financing. Identified seeks to gamify career development and job searching. VantagePoint Capital Partners and Capricorn Investment Group co-led the round with participation from previous investors including Tim Draper, Bill Draper and Innovation Endeavors. Identified has raised a total of $22.5 million since it was founded in 2010.
