Jive Software, a social business software provider, has closed USD30m in series C financing.

Kleiner Perkins Caufield & Byers led the investment, with continued participation from Sequoia Capital, the only venture investor in Jive up until now.

Ted Schlein (pictured), managing partner at Kleiner Perkins, will join Jive's board of directors.

"Social business is the most important enterprise software category in a decade," says Schlein. "Jive is the clear market leader, with a strong customer base, best-in-class technology and a deep management team. Jive is poised to become the next great enterprise software company."

"We are thrilled to have Ted join the Jive team," says Jim Goetz, general partner, Sequoia Capital. "Ted has a demonstrated track record of building market leading companies, both as a former senior executive at Symantec and investor at KPCB."

"We are honoured to welcome KPCB to Jive, and to receive Sequoia's unwavering commitment," adds Tony Zingale, Jive's chief executive. "KPCB and Sequoia are unparalleled at building great companies. We are privileged to have them both on our team."

Jive helps companies like Charles Schwab, Intel, Nike, and VMware adopt social business to improve competitive advantage, profitability and growth.

Jive SBS combines the power of community software, collaboration software, social networking software and social media monitoring offerings into an integrated social platform.

The social business software market is projected to grow in excess of 25 per cent per year and will reach nearly USD5bn by 2013.
