Andreessen Horowitz

Andreessen Horowitz (also called a16z, legal name AH Capital Management, LLC) is a private American venture capital firm, founded in 2009 by Marc Andreessen and Ben Horowitz. The company is headquartered in Menlo Park, California. As of April 2023, Andreessen Horowitz ranks first on the list of venture capital firms by assets under management, with $42 billion as of May 2024.

Andreessen Horowitz invests in both early-stage start-ups and established growth companies. Its investments span the healthcare, consumer, cryptocurrency, gaming, fintech, education and enterprise IT (including cloud computing, security, and software as a service) industries.

Founding and partnering
Between 2006 and 2010, Marc Andreessen and Ben Horowitz actively invested in technology companies. Separately, and together, they invested $4 million in 45 start-ups including Twitter. During this time, the two became known as "super angel" investors.

On July 6, 2009, Andreessen and Horowitz launched their venture capital fund with an initial capitalization of $300 million. In November 2010, at a time when the field of venture capitalism was contracting, the company raised another $650 million for a second venture fund. In less than two years, the firm was managing a total of $1.2 billion under the two funds.

In May 2011, Andreessen ranked number 10 on the 2011 Forbes Midas List of Tech's Top Investors while he and Horowitz ranked number 6 on Vanity Fair's 2011 New Establishment List and number 1 on CNET's 2011 most influential investors list.

As of March 27, 2014, the firm managed $4 billion in assets after the closing of its fourth fund at $1.5 billion.

In addition to Andreessen and Horowitz, the firm's general partners include John O'Farrell, Scott Weiss, Jeff Jordan, Peter Levine, Chris Dixon, Vijay Pande, Martin Casado and Sriram Krishnan. In March 2019, it was reported that Andreessen Horowitz was opening an office in San Francisco.

In January 2022, Andreessen Horowitz raised $9 billion for its venture capital, growth-stage and biotech-focused vehicles.

As of May 2024, the firm manages $42 billion in assets.

2009
In 2009, Andreessen Horowitz made its two first investments: one in business management SaaS developer Apptio and the other in Skype stock. According to Horowitz, the investment was seen as risky by other experts in the field who believed the company would be crippled by ongoing intellectual property litigation and direct competitive attacks from Google and Apple. The company's founders viewed the investment as a success following Skype's sale to Microsoft in May 2011 for $8.5 billion.

2010–2011
In 2010, Andreessen Horowitz invested $10 million in cloud company Okta while leading its Series A Round.

Andreessen Horowitz has also invested in Airbnb, Lytro, Jawbone, Belly, Foursquare, Stripe and other high-tech companies.

2012–2013
In 2012, Andreessen Horowitz invested in 156 companies, including the 90 companies in its portfolio, and 66 start-ups through its funding of Y Combinator's Start Fund.

In 2013, Andreessen Horowitz invested in Clinkle, Coinbase, Databricks, Lyft, Oculus VR, PagerDuty, Pixlee, Ripple, Soylent, Swiftype and uBiome.

In December 2021, crowdfunding platform Kickstarter received a $100 million investment from a16z's crypto fund with the expectation that it would pivot to blockchain technology. The decision to pivot backfired, alienated many of Kickstarter's users, and ended up damaging its reputation.

2022
In March 2022, Andreessen Horowitz led the round to raise $450 million at a $4B Valuation in Yuga Labs (known for Bored Apes). In October 2022, it was reported that the US Securities and Exchange Commission were investigating Yuga Labs, due to concerns that sales of their digital assets violated US investment laws.

The firm stated that $1.5 billion was allocated to seed investments while the remaining $3 billion would be earmarked for venture investments.

In August 2022, the firm announced it would be investing about $350 million in Flow, the latest organization begun by WeWork founder Adam Neumann. The purported aim of Flow is to create a branded product in the housing market with consistent community features, reimagining how real estate works in the US. The decision was met with some criticism due to Neumann's previous business issues in his time at WeWork.

The firm committed to $400 million in equity investment towards acquisition of Twitter by Elon Musk that completed in October 2022.

Structure
Andreessen Horowitz partners work on behalf of all its portfolio companies, an approach modeled after the Hollywood talent agency, Creative Artists Agency. In 2010, the company hired Margit Wennmachers, a marketing executive at the partner level.

As of 2011, the firm had maintained a database of designers, coders, and executives and used it to help fill positions at its start-ups. Former U.S. Treasury Secretary Larry Summers became a special advisor to Andreessen Horowitz in June 2011.

In September 2012, former Washington D.C. mayor Adrian Fenty was appointed Andreessen Horowitz's second special advisor. Fenty was hired to advise the firm's portfolio companies on working with local, state, and federal governments.

In 2019, the firm applied to restructure as a registered investment adviser in order to have more freedom to take up riskier bets like cryptocurrency.

In 2023, the firm announced that it is establishing a cryptocurrency-investment entity in London, United Kingdom.
