Cloud CRM firm salesforce.com has announced revenue of $546m for Q2 FY12, a climb of 38% year over year, the fastest growth rate for three years.

Despite the impressive growth and revenue figures the firm still slipped to a $4.3m loss, compared to income of $14.7m this quarter last year.

Salesforce.com’s revenue consisted of $509m from subscriptions and support, which was also up 38%, and $37m from professional services and "other". This represented a 44% climb year over year.

The company added 6,300 new customers during the quarter, which it says is a record, and now has a customer base of 104,000 customers.

Founder and CEO Marc Benioff said the company was closing in on a revenue milestone. "Just 2 quarters now into our fiscal year and we will soon exceed a $2.2 billion annual revenue run rate, validating both our growth strategy and our ability to execute on the incredible opportunity," he said.

"Given this strong financial and customer momentum, we’re again, raising our full year fiscal year ’12 revenue guidance, which we now project at $2.22bn to $2.23bn," he added.
