Ben Horowitz
Benjamin Aaron Horowitz (born June 13, 1966) is an American entrepreneur, venture capitalist, and author.[1] He co-founded the venture capital firm Andreessen Horowitz (a16z) with Marc Andreessen in 2009. Before becoming a venture capitalist, Horowitz co-founded and served as CEO of Opsware (formerly Loudcloud), which he sold to Hewlett-Packard for $1.6 billion in 2007. His book The Hard Thing About Hard Things became a seminal guide for technology entrepreneurs navigating the challenges of building companies.
Early Life and Education
Family Background
Horowitz was born in London, England, to American parents. His father, David Horowitz, was a prominent left-wing activist and writer who later became a conservative commentator - a political journey that influenced Ben's own thinking about ideology and pragmatism.
The family moved to Berkeley, California, where Horowitz grew up amid the politically charged atmosphere of the 1970s.
Education
Horowitz earned a Bachelor of Arts degree in Computer Science from Columbia University. He later earned a Master of Science in Computer Science from UCLA.
Personal Life
Family
Horowitz married Felicia Wiley, an African-American woman, in 1988. The interracial marriage influenced his perspectives on race, culture, and business. The couple has three children and resides in the San Francisco Bay Area.
Hip-Hop Influence
Horowitz is an avid hip-hop fan who frequently references rap lyrics in his blog posts and public speeches. His book What You Do Is Who You Are draws management lessons from figures including Toussaint Louverture, samurai warriors, and hip-hop artists like Ice Cube.
He has stated that hip-hop's emphasis on authenticity, struggle, and creative expression resonates with entrepreneurship.
Career
Silicon Graphics (1990-1995)
After UCLA, Horowitz joined Silicon Graphics (SGI) as an engineer, working on networking and server products during SGI's peak years.
Netscape (1995-1999)
In 1995, Horowitz joined Netscape Communications as a product manager, where he first met Marc Andreessen. At Netscape, he rose to become Vice President and General Manager of the Enterprise product line.
When AOL acquired Netscape in 1999, Horowitz led the integration of Netscape's enterprise products into the new AOL/Netscape.
Loudcloud/Opsware (1999-2007)
Founding
In 1999, Horowitz co-founded Loudcloud with Marc Andreessen, Tim Howes, and In Sik Rhee. The company aimed to provide "cloud computing" infrastructure - a concept ahead of its time.
Dot-Com Crash
Loudcloud went public in March 2001, just as the dot-com bubble collapsed. The company faced existential crisis:
- Revenue plummeted as customers went bankrupt
- The stock fell from $6 to below $1
- Horowitz had to lay off hundreds of employees
The Pivot
In 2002, Horowitz made a bold pivot: selling Loudcloud's managed services business to EDS for $63.5 million and transforming the remaining company into Opsware, an enterprise software company selling data center automation software.
The transformation required rebuilding the entire business, product, and team.
Sale to HP
Over the next five years, Horowitz rebuilt Opsware into a successful enterprise software company. In 2007, Hewlett-Packard acquired Opsware for $1.6 billion - a remarkable turnaround from near-bankruptcy.
Andreessen Horowitz (2009-Present)
Founding
In July 2009, Horowitz and Marc Andreessen founded Andreessen Horowitz (commonly known as "a16z"). The firm launched with $300 million, one of the largest first-time funds ever.

Andreessen Horowitz pioneered a new venture capital model:
- Large support teams: Marketing, recruiting, corporate development assistance for portfolio companies

Books
The Hard Thing About Hard Things (2014)
Horowitz's first book, The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers, became a bestseller and one of the most influential business books of the 2010s.
Unlike typical business books focusing on success, it addressed:
- Firing your friend
- Managing through layoffs
- The loneliness of CEO life
- Surviving near-death experiences
What You Do Is Who You Are (2019)
His second book examined organizational culture through unconventional case studies including:
- Toussaint Louverture and the Haitian Revolution
- Samurai culture
- Genghis Khan's management techniques
- Prison gang culture
Philosophy
"Peacetime CEO/Wartime CEO"
Horowitz introduced the concept of "peacetime" vs. "wartime" CEOs:
- Peacetime: Expanding markets, reinforcing strengths, methodical growth
- Wartime: Existential threats, decisive action, unconventional tactics
"The Struggle"
He frequently discusses "The Struggle" - the emotional toll of entrepreneurship - normalizing the psychological challenges that founders face.
Culture
Horowitz emphasizes that "culture is not a set of beliefs - it's a set of actions." He argues that what a company does, not what it says, defines its culture.
Controversies
a16z Political Activities
a16z has faced criticism for its active lobbying on cryptocurrency regulation and its political commentary, with some arguing venture capitalists should focus on investing rather than politics.
Web3 Skepticism
The firm's heavy investments in cryptocurrency have drawn skepticism, particularly during the 2022 crypto winter when many investments lost significant value.
