Fast-growing business intelligence software company Splunk — a San Francisco company that established a branch office in Seattle last year — has filed to raise up to $125 million through an initial public offering.

Today’s filing should not come as a big surprise, since Bloomberg News reported last October that the company was considering an IPO that could value the company at close to $1 billion.

In addition to operating a branch office in Seattle, Splunk has other ties to the region. Bellevue-based Ignition Partners led a $25 million round in Splunk in 2007, with the firm’s John Connors joining the board.

Ignition holds a 12.3 percent stake in the company. August Capital and Sevin Rosen each hold 20.7 percent, while JK&B Capital holds 17 percent.

Splunk had $77 million in revenue for the nine months ended October 31st. That was up from $43 million for the same period last year. It lost $9.7 million during the nine-month period in 2011.

It plans to trade under the ticker SPLK.

Companies such as Seattle daily deal site Zulily use Splunk to analyze site traffic and better predict site outages
