StrikeIron, a venture-capital backed data software firm that launched in 2003, is now part of Informatica, a California-based data integration and software management firm.

The deal closed on Thursday but was not announced beyond a mention of StrikeIron’s website. 

In a telephone interview later, Debbie O’Brien, vice president for global communications at Informatica (Nasdaq: INFA), would not disclose financial terms of the deal but did discuss other aspects.

“This is a great deal for us,” said O’Brien, noting that Informatica had been a business partner with StrikeIron for several years.

“We just decided it was time to bring them in,” she explained, noting that StrikeIron offerings mesh well with those of a company called Address Doctor, which Informatica acquired in 2009.

Among the “in” are StrikeIron’s 50 employees, led by Sean O’Leary who had been CEO. O’Leary will serve as senior vice president for data services strategy within an existing Informatica business unit, O’Brien said.

However, Bob Brauer, one of the firm’s co-foundfers and its chief technology officer, has left to pursue other ventures, O’Brien said.

The Cary office will otherwise “remain unchanged,” she added.

Informatica already has a small office in the Triangle area. The lease of the StrikeIron office space is through 2016. Whether Informatice will combine or expand or move its Triangle location will be discussed later, she said.

StrikeIron has experienced strong growth over the past four years, reporting that its revenues have grown 400 percent. The company ranked No, 1,652 on the Inc. 5000 list in 2013.

The company was launched by Brauer, Richard Holcomb and Robert Dale in 2003. Investors include Aurora Funds and IDEA Fund Partners in Durham. 

Brauer, who was chief technology officer at StrikeIron, also was a founder of Cary-based DataFlux.

Holcomb helped launched two other Triangle software firms, HAHT and Q+E.
