Andreessen Horowitz

Andreessen Horowitz, commonly abbreviated as a16z, was founded by Marc Andreessen and Ben Horowitz in 2009. The firm invests from the seed and venture stages through the growth stage, covering fields such as artificial intelligence, bio and healthcare, consumer, crypto, fintech and infrastructure.⁠[1]

In July 2009, Andreessen Horowitz launched its first venture capital fund of $300 million, with only two general partners, Marc Andreessen and Ben Horowitz. The fund would make individual investments ranging from $50,000 to $50 million, but would generally focus on early-stage opportunities.⁠[2][3]

Andreessen argued at the time that only about 15 companies started each year really matter: they have the potential to generate $100 million or more in annual revenue and account for about 97% of the industry’s aggregate returns, so the fund wanted the flexibility to invest anywhere from $500,000 to $50 million in those companies. He also argued that the biggest hits come when founders stay engaged in a C-level position, and the two partners would not always take board seats in portfolio companies.⁠[2][2][2][2]

Ben Horowitz later recalled that soon after its founding a16z joined Silver Lake and the Canada Pension Plan Investment Board in buying a majority stake in Skype from eBayeBayeBay Inc. is an online marketplace company headquartered in San Jose, California, United States, founded in 1995 by Pierre Omidyar; it started out with person-to-person online auctions and listed on Nasdaq in 1998. As of the end of 2025, it had 135 million active buyers, and its platform’s gross merchandise volume in 2025 was nearly $80 billion.Open the full entry. At the time, the deal faced an intellectual property dispute and the risks of the shift to the mobile internet; it is an example of the firm’s early multi-stage investing.⁠[4]

On November 2, 2010, Andreessen Horowitz announced that its second fund had closed at $650 million after about three weeks of fundraising, bringing the firm’s capital under management to about $950 million. At the time it had an investment staff of 18, and its portfolio included Skype, Zynga and Foursquare, among others.⁠[5][5]

Ben Horowitz said the firm did not raise more because it did not want fund size to dictate its investment pace. He disagreed with limited partners’ preference for specialized funds that invest only in seed, only in growth or in specific sectors, arguing that the quality and pricing of different stages vary a great deal over time. He also said the fund would not turn to the global market, because building big companies in a repeatable way is harder elsewhere.⁠[5][5][5][5]

On August 20, 2011, Marc Andreessen published “Why Software Is Eating the World,” declaring that “software is eating the world” and listing companies Andreessen Horowitz had already invested in, including Facebook, Groupon, Skype, Twitter, Zynga and Foursquare. Looking back in 2024, Ben Horowitz said the prediction had come true; the a16z website also sums up the firm’s founding conviction as “software would eat the world.”⁠[6][6][3][1]

The closing was an M&A milestone for the portfolio company, but Microsoft’s annual report does not separately disclose a16z’s cash distributions or return multiple.⁠[7][4]

On January 31, 2012, Ben Horowitz confirmed that Fund III had closed at $1.5 billion, bringing the firm’s total capital under management to $2.7 billion; the fund could invest anywhere from $10,000 to $100 million in startups and growth companies. The firm then had six general partners: Jeff Jordan, Peter Levine, John O’Farrell, Scott Weiss, Horowitz and Andreessen.⁠[8][8][8]

Horowitz also released figures on the firm’s network services: in 2011, the firm hosted more than 600 portfolio presentations to corporate customers and partners at its Menlo Park office, leading to more than 3,000 introductions to senior executives at Fortune 500 and Global 2000 companies; it had relationships with more than 4,000 engineers, designers and product managers and made more than 1,300 introductions to portfolio companies, resulting in 130 hires.⁠[8][8]

On June 10, 2016, Andreessen Horowitz confirmed that its fifth fund had closed at $1.5 billion, with commitments from its existing investors. About two years earlier, its fourth multi-stage fund had also closed at $1.5 billion; in November 2015, the firm set up the separate $200 million AH Bio Fund, which invests mostly in early-stage companies at the intersection of computer science and life sciences. This brought the firm’s total capital raised to about $6.2 billion.⁠[9][9][9][9]

Managing partner Scott Kupor said about 70% of the new fund’s investments would go to early-stage companies and the rest to later-stage ones; seed investing had shifted from many small $50,000 checks in the early years to investments of $500,000 to $1.5 million as a major investor. The firm then had eight general partners: Scott Weiss was sitting out this fund, and Alex RampellAlex RampellAlex Rampell (Alastair Rampell) is an entrepreneur and investor, a general partner at Andreessen Horowitz and leader of its Apps practice.

In March 2019, a16z filed to convert from an exempt venture capital firm into a registered investment adviser (RIA) in order to gain more flexibility in its investments, especially in cryptocurrencies: in the United States, venture capital funds may not hold more than 20% of their money in liquid securities such as cryptocurrencies. As a registered investment adviser, the firm could experiment in new areas such as public markets, other VC funds and cryptocurrencies.⁠[13][13][14]

In May of the same year, the firm had also invested $70 million in Flowcarbon, a carbon credit platform Neumann co-founded.⁠[29][29][29][29]

Andreessen called Neumann a “visionary leader” and argued that Flow directly addressed America’s housing shortage and the lack of community in renting, but did not disclose the terms of the investment.

Horowitz argued that each submarket—American Dynamism, Apps (consumer, enterprise and fintech), Bio + Health, Crypto, Games, Growth and Infrastructure—had become as big as the entire original venture capital market, so the firm had created dedicated funds, each with its own team of experts and capabilities, rather than having one investor cover several fields.⁠[3][3][3]

a16z’s investment announcement was co-signed by Jennifer Li, Sarah Wang, Martin Casado, Marc Andreessen and Ben Horowitz. They said TypeSafe’s Jev model hands model decisions directly to code as typed values, costs roughly 1/100 to 1/500 as much as frontier models and is about 100 times faster on classification tasks at comparable accuracy; Jev generated 1 trillion tokens in its first three days, thousands of use cases appeared in its first week, and 25% of Fortune 500 enterprises had integrated it. They argued that AI should make software more powerful rather than just automate the recreation of existing software, and closed with “Software continues to eat the world.”⁠[56][56][56][56][56][56][56][56]
