About
Ben Horowitz ran Loudcloud and Opsware through the dot-com crash and sold the company to HP for $1.6 billion before co-founding Andreessen Horowitz in 2009. He led the firm's investments in companies such as Okta, Databricks, and Nicira, and writes about management with a signature habit of opening chapters with rap lyrics. His two books on leadership and company culture are staples of startup reading lists.

America’s software leadership was built on openness. We have the same opportunity in AI. If we want a competitive, secure AI ecosystem whose benefits extend far beyond a handful of companies, we need to preserve access to open-weight models. https://t.co/oD6YeYVwaW
