. After being shown the ViolaWWW graphic web browser in late 1992, Andreessen and full-time salaried co-worker Eric Bina worked on creating a browser with integrated graphics that could be ported to a wide range of computers, including Windows. The result was the Mosaic web browser released in 1993.


Career

During his career, Andreesen has worked at Netscape, Opsware, founded Andreessen Horowitz and invested in many successful companies including, Facebook, Foursquare, GitHub, Pinterest, LinkedIn and Twitter.


Netscape

After his graduation from UIUC in 1993, Andreessen moved to

, with Andreessen as co-founder and vice president of technology. The University of Illinois was unhappy with the company's use of the Mosaic name, so Mosaic Communications changed its name to Netscape Communications, and its flagship Web browser was the Netscape Navigator. Netscape's IPO in 1995 put Andreessen into the public eye. He was featured on the cover of ''

Opsware

After AOL acquired Netscape in late 1998, Andreessen went on to found Opsware with Ben Horowitz, Tim Howes, and In Sik Rhee. Originally named Loudcloud, the company provided computing, hosting and software services to consumer facing internet and e-commerce companies. Loudcloud sold its hosting business to EDS and changed its name to Opsware in 2003, with Andreessen serving as chairman. Acquired by Hewlett-Packard for $1.6 billion in 2007, it was one of the first companies to offer software as a service and to attempt cloud hosting.


Andreessen Horowitz

Between 2005 and 2009, Andreessen and longtime business partner Ben Horowitz separately invested a total of $80 million in 45 start-ups that included

. The two became well known as super angel investors. On July 6, 2009, Andreessen and Horowitz announced their Silicon Valley venture-capital firm Andreessen Horowitz. The firm had been scrutinized among several other venture capital firms for lack of diversity in its workforce. In an interview with ''New York Magazine'', Andreessen stated the diversity discussion was valid, however, he believed the firm, as well as other venture capital firms of Silicon Valley, had been wrongly accused of intentionally discriminating against women and people of color. When asked specifically about the critique of ethnic and gender diversity in Silicon Valley, Andreessen responded that the issues were the "same thing."


Investments

Begun with an initial capitalization of $300 million, within three years the firm grew to $2.7 billion under management across three funds. Andreessen Horowitz's portfolio holdings include

in creating the first free standardized seed round financing documents, the Series Seed Documents. Andreessen first joined the eBay board of directors in 2008, and served on it for six years. In October 2014, Andreessen announced his resignation from the board due to the company's decision to break off its online payments unit PayPal. The decision to cut ties with PayPal was a point of contention between Andreessen and investor Carl Icahn. Icahn advocated for the PayPal split while Andreessen opposed the spin off, resulting in public disputes. Andreessen was accused by Icahn of putting his own interests in front of what was best for shareholders. Icahn published his argument in an open letter that detailed alleged conflicts of interest in eBay's 2009 sale of Skype to a group of private investors, which included Andreessen's own firm.

). Facebook spent millions advertising Free Basics to the Indian public. The project failed due to violations, setting preferential tariffs in accessing content and setting up a "walled garden" on the internet.


Conflict of interest

In April 2016, Facebook shareholders filed a class action lawsuit to block Zuckerberg's plan to create a new class of non-voting shares. The lawsuit alleges Andreessen secretly coached Zuckerberg through a process to win board approval for the stock change, while Andreessen served as an independent board member representing stockholders. According to court documents, Andreessen shared information with Zuckerberg regarding their progress and concerns as well as helping Zuckerberg negotiate against shareholders. Court documents included transcripts of private texts between Zuckerberg and Andreessen.

's immigration stance. In 2021, he and his wife bought a property in Malibu for $177 million from Serge and Florence Azria. This was the highest price paid for a California property at that time. In 2022, Andreessen advocated against the construction of 131 multifamily housing units in their affluent Atherton, California town. In a letter, Andreessen and his wife wrote that they opposed permitting more than one house on a single acre of land. Andreessen's comments sparked criticisms of hypocrisy, as he had previously argued for increased housing supply, in particular in California. In 2022, Andreessen's plane was returning to Los Angeles when the nose gear failed to operate before landing. After circling the runway several times, the plane landed safely without the nose gear. Andreessen has a chapter in Tim Ferriss' book '' Tools of Titans''.
