Microsoft has acquired ad pricing software company Rapt for an undisclosed amount.

San Francisco-based Rapt’s software helps web sites get the most money out of their ads through pricing and other strategies. Microsoft says it will include Rapt’s technology in its Atlas Publishing Suite.

We previously covered Rapt after two of its co-founders sued the company’s chief executive and investors Accel Partners and Levensohn Venture Partners for breach of fiduciary duty and fraud. They settled 10 days later.
