Indian outsourcing-services company Wipro Ltd. said Tuesday it agreed to acquire a minority stake in Opera Solutions LLC, a U.S.-based provider of data-processing tools, for $30 million. A press release from Wipro didn't provide details of the stake it will own in privately held Opera Solutions. The New Jersey-based company provides tools to process raw data and make predictive analysis and find specific facts. It has 700 employees, according to its website. Wipro is buying the stake at a time global companies like International Business Machines Corp. are also expanding their data-processing and business-intelligence capabilities as they find opportunities in these businesses.
