...Centrum.cz, the Czech firm said on Tuesday.
NetCentrum disclosed neither the price nor the size of the stake that Warburg Pincus is taking.
Intel Capital and Baring Communications Equity had invested in the company in 2000.
NetCentrum, which competes with market leader Seznam.cz, said it would like to take advantage of Warburg's investment to expand across central and eastern Europe and improve its service portfolio.
The company's co-founders retain a minority stake. (Reporting by Marek Petrus; Editing by David Holmes)
