Cloudera
Founded: 2008
Before there was the term "big data" there was Cloudera. The computing platform, created by Olson, 50, and a dream team of engineers from Google (GOOG, Fortune 500), Yahoo (YHOO, Fortune 500) and Facebook (co-founders Christophe Bisciglia, Amr Awadallah and Jeff Hammerbacher, respectively) allows IT departments to deploy Hadoop, the powerful but unwieldy open-source framework that processes and stores massive amounts of data. Today "big data" is translating into big business for Cloudera. Customers include eBay, Nokia (NOK), Orbitz (OWW), and Chevron (CVX, Fortune 500), and the company is valued at $700 million.
