After five and a half years as the chief executive of Ning, the Palo Alto, Calif.-based social network platform provider, Gina Bianchini has decided to step down from her position and is being replaced by current chief operating officer and former Netscape and Opsware executive, Jason Rosenthal. Bianchini is becoming an executive in residence (EIR) at Marc Andreessen’s venture capital firm, Andreessen Horowitz.
“Nothing else is changing — I remain Chairman, the current management team remains exactly the same, and the Ning service continues unchanged,” says Andreessen, chairman and co-founder of Ning. The company says it has 2.3 million user-created Ning Networks and more than 45 million registered users and is adding million new registered users every 12 days and and 5,000 Ning-powered networks every day. The company has raised more than $110 million in funding and is valued at over $500 million.
