Andreessen Horowitz

Andreessen Horowitz (also known as a16z) was founded in 2009 by Marc Andreessen and Ben Horowitz. Before starting the firm, both founders invested extensively in IT startups, a focus that is reflected in the company's current portfolio. The firm is headquartered in Menlo Park, California.

Andreessen Horowitz describes itself as "stage agnostic," stating that it invests "in seed to late-stage technology companies, across the consumer, enterprise, biotech, healthcare, crypto, and fintech spaces." The firm also identifies a focus on what they call American Dynamism, maintaining a portfolio of companies that advance American interests and national security. Among other specific funds, Andreessen Horowitz has what it calls the Cultural Leadership Fund, whose purpose is to pursue opportunities that will bring more African American leaders into technology fields. The firm reports to have "$28.2 billion in assets under management across multiple funds." Andreessen Horowitz has invested in a number of companies that have gone on to high profile IPOs, including Airbnb, Facebook, Lyft, Groupon, Pinterest, and Zynga.
