Blog search engine Technorati, which was simultaneously pitching a sale through Montgomery & Co. as well as a new venture round, raised $7.5 million in a fourth round of financing according to a regulatory filing. Investors include Draper Fisher Jurvetson, Mobius Venture Capital and FG Incubation.

I spoke with Technorati CEO Richard Jalichandra this evening, who confirms that a venture round has been closed and says that the company will make an announcement next week that includes more information.

Its also clear that the company is refocusing its business. We believe they are launching a blogger-focused advertising network based on documents we published in February. The company has, however, considered other strategies recently, including a blog rollup. Well know more next week.
