The Vertical AI Agent Goldrush: Where the Next $1B Companies Hide

Horizontal AI is a race between hyperscalers. Vertical AI is a race between founders who understand a niche better than the incumbent software vendor.

Why vertical wins now

Frontier models are commoditised. The moat is workflow + data + trust in a specific industry. Vertical agents ship with pre-wired integrations, compliance, and vocabulary — none of which a horizontal chatbot has.

The pattern that recurs

1) A boring vertical with $50–$500B TAM. 2) An incumbent SaaS from 2005–2015. 3) A workflow that's 60% typing/reading. 4) Regulated data that big AI companies won't touch. Every $100M+ vertical AI story fits this shape.

Key takeaways

  • Ignore horizontal. Chase boring verticals with typing-heavy workflows.
  • The moat is domain data + trust, not model access.
