Founded in 2009 by Marc Andreessen, the co-creator of the Netscape browser, and Ben Horowitz, a former enterprise software executive, a16z set out to build a different kind of VC firm - one staffed with in-house recruiters, marketers, and engineers to support founders directly, not just write checks. The firm's stage-agnostic, software-eats-the-world thesis has since carried it into crypto, biotech, and AI, backing companies from seed rounds through late-stage growth across every category it touches.

That regulated-finance operating background, rather than a conventional Silicon Valley career arc, is what made Ribbit the premier financial-services specialist in venture capital, backing category leaders globally from a first $100 million fund in 2013. The firm's public messaging has since broadened well past 'fintech' into global commerce, money movement, identity, data, energy, AI, and wealth management, but the through-line is unchanged: Coinbase, Nubank, and Robinhood are all Ribbit bets, and its March 2026 Form ADV reports approximately $20.78 billion in regulatory assets under management.
