What It Takes to Win as a Founder | Ben Horowitz

Andrew Chen interviews a16z co-founder Ben Horowitz about what AI changes—and doesn’t—in entrepreneurship. Horowitz argues AI can help tiny teams reach huge audiences fast, but durable winners still need 10x products, proprietary data, and decisive leadership; CIOs should note his view that AI is creating a new application layer and reshaping venture dynamics.

Key points

• AI behaves like a new computer: useful products can reach massive audiences almost instantly, unlike earlier network-era launches.
• Tiny teams can build billion-dollar businesses, but sustaining them against copycats and larger competitors remains the challenge.
• Defensibility comes from a dramatically better product, customer data, and switching costs—not from dismissing products as 'wrappers.'
• The application paradigm may fade toward data plus agents that perform tasks directly against it.
• Great CEOs and founders must decide quickly under uncertainty; hesitation breeds politics and slows execution.
• VCs increasingly add momentum, hiring help, and founder confidence, not just capital and board advice.
