Netscape’s stock launch in 1995 gave Andreessen great fame. Many publications featured his work, and he was featured on the time magazine’s cover. 

AOL purchased Netscape in 1999 for $4.3 billion. AOL named Andreessen chief technology officer as part of the deal. According to the MIT Technology Review, he was one of the world’s top 100 innovators under 35 years of age.


After Netscape was acquired in 1999, Andreessen founded Loudcloud along with Ben Horowitz, Tim Howes, and In Sik Rhee. It provided services like hosting, computing, and software to web companies that cater to consumers. 

Loudcloud changed its name to Opsware in 2003 after selling its hosting business to Electronic Data Systems; Andreessen served as chairman of the board. Afterward, Hewlett-Packard bought Opsware in 2007 for $1.6 billion.
