We, like so many others, have joked about Twitter’s non-existent business model and its frothy billion-dollar valuation. Apparently we might have to stop that – at least for now. The San Francisco-based micromessaging company is said to be profitable, according to a report in Bloomberg that quotes someone close to the company. The profitability might be shortlived, however, as Twitter continues on path of hyper-growth.

The company is going to bring in revenue of $25 million, thanks to its search deals with Google and Microsoft. Google is paying the company $15 million a year, while Microsoft is paying it $10 million for access to its real-time data. The company, Bloomberg claims, has operating costs of $20-$25 million a year, which allows it to be slightly profitable for 2009. According to some estimates the company, which has 105 employees, is likely to have revenues of $114-$134 million in 2013, sans profits.
