Everyone's watching OpenAI and Google. Meanwhile, these five companies just closed massive rounds with almost zero mainstream coverage — and they're building in sectors most investors aren't paying attention to yet.

1. Applied Intuition — Autonomous vehicle simulation. Defense contracts are accelerating their revenue faster than anyone expected.

2. Glean — Enterprise AI search. They're doing what Google couldn't inside corporate environments. Revenue reportedly tripled in 12 months.

3. Harvey — AI for legal. If you think lawyers won't adopt AI, their growth numbers say otherwise. Law firms are racing to deploy.

4. Hebbia — AI-powered financial analysis. Hedge funds and PE firms are already using it to parse thousands of documents in minutes instead of weeks.

5. Physical Intelligence — Robotics foundation models. This is the "pre-ChatGPT moment" for robots. The team is ex-Google DeepMind.

The pattern? Vertical AI — companies building deeply specialized tools for specific industries — is where the real money is flowing. Horizontal AI gets the headlines. Vertical AI gets the returns.

I track these moves daily inside The AI Wire. If you're investing in AI and not watching the B2B vertical plays, you're looking at the wrong scoreboard.
