SuccessFactors, a provider of cloud-based HR management software for enterprises, announced it acquired Jobs2Web for $110 million. The news comes about four days after it revealed it is becoming a subsidiary of business software maker SAP, as a part of a much bigger $3.4 billion transaction.

SuccessFactors said that the delay was a result of the deal not yet being final on December 3, which confirms the fact negotiations were long underway before the announcement of its own acquisition.

The service is reportedly leveraged by several large enterprises such as Rackspace and Taco Bell; something that SuccessFactors CEO Lars Dalgaard backed up during an interview with Bloomberg:

“He declined to disclose Jobs2Web’s sales, saying only that it has about 120 employees and is growing faster than SuccessFactors’ own 77 percent third-quarter revenue growth.

“I’m going to do a lot more with this,” he said, referring to Jobs2Web’s technology.”

It’s easy to see how Jobs2Web supplements SuccessFactors’ own platform. The former offers a social media headhunting solution called the Recruiting Execution Platform, which leverages Facebook, Twitter and other networks to optimize the process of finding the right candidates. Once they’re tracked down via these sources, SuccessFactors provides the tools to handle the rest of the internal process.

Jobs2Web will be immediately integrated into the Business Execution line of apps, according to a statement.

Under SAP management SuccessFactors will operate as an independent subsidiary and will be free to make other acquisitions, particularly ones that go side by side with SAP’s agenda. The German firm is looking at the cloud, social media and mobile as three key drivers in its near-term growth, and the SuccessFactors deal marks an official entry into a space that weaves two of those trends together within the enterprise.
