Marc Andreessen co-founded Netscape, the first successful commercial web browser, and later co-founded the venture capital firm Andreessen Horowitz.[1][2] Donald Trump gained Andreessen as an advisor during 2024.[3]
Life and work
He moved to California and met Jim Clark, who believed Mosaic had commercial possibilities.[4] They founded Mosaic Communications Corporation, which became Netscape Communications.[4] He co-founded Opsware (originally Loudcloud), which Hewlett-Packard acquired for $1.6 billion in 2007.[5][6] Andreessen co-founded and chaired Ning, which was sold to Mode Media in 2011.[7]
After viewing the ViolaWWW browser, Andreessen collaborated with Eric Bina to develop the Mosaic web browser, which saw its release in 1993.[8] Because the NCSA declined to acknowledge the Mosaic team's work, Andreessen departed the center in 1994.[9] Andreessen gained widespread recognition following Netscape's 1995 initial public offering and subsequently featured on Time's cover.[10] AOL purchased Netscape for $4.3 billion in 1999, after which Andreessen assumed the role of chief technical officer.[11]
The venture-capital firm Andreessen Horowitz was publicly launched by Andreessen and Ben Horowitz in 2009.[2]
What the cited sources add
The Centre for Computing History notes that Netscape's IPO in 1995 propelled Andreessen into the public's imagination.[4] The Mozilla Blog states that Mosaic, released on January 23, 1993, was the first browser with blue hyperlinks.[12] CNBC reports that Andreessen Horowitz launched a $2.2 billion crypto-focused fund in 2021 and a $4.5 billion fund in 2022.[13][14] TechCrunch describes the American Dynamism fund launched in 2023, which backs hard tech sectors serving national interest.[15]
