## About

Ben Horowitz's family office was established after his career as co-founder of the venture capital firm Andreessen Horowitz (a16z) in 2009, which grew to manage over $42 billion. The wealth origin is tied to Horowitz's prior success as a technology executive and co-founder of Opsware (sold to Hewlett-Packard in 2007 for $1.6 billion, per The New York Times, 2007) and his ongoing general partnership role at a16z. The office's strategy spans multiple asset classes, including direct equity investments in startups, digital assets, and alternative venture structures like rolling funds and special-purpose vehicles. Sector focuses include FinTech (e.g., Coinbase investment via a16z), ClimateTech, Workflow Automation, Media & Entertainment, and Web3 & Blockchain. The geographic focus is primarily North America, with capital deployed across Seed, Early Stage, and Growth stages. Confirmed portfolio exposures include Coinbase, OpenAI, and various a16z-led deals where Horowitz invested personally. Total AUM is undisclosed. Team size and office structure are not publicly reported. The office operates without a separate LinkedIn presence or dedicated website, functioning as a lean entity tied to Horowitz's personal wealth. No philanthropic foundation or adjacent operating vehicles have been publicly confirmed as separate from a16z's broader activities. The structural differentiator is its symbiotic relationship with Andreessen Horowitz: the office leverages a16z's proprietary deal flow and network while maintaining independent capital allocation. This allows Horowitz to participate in a16z-led deals personally and also pursue investments outside the firm's mandates (e.g., direct digital asset holdings). Succession and governance details are not public.
