Four Fits

Before you scale, all four fits must work. If one is broken, scaling fails.

Most companies scale too early. They have product-market fit and think they're ready. They're not. You need all four:

  1. Market ↔ Product - Do customers want this?
  2. Product ↔ Channel - Can you reach customers efficiently?
  3. Channel ↔ Model - Can your business model support acquisition costs?
  4. Model ↔ Market - Can you monetize this market profitably?

One broken fit = don't scale yet. Fix it first.

Philosophy: "All four fits must align for $100M+ growth. Scaling with misaligned fits burns cash." - Brian Balfour
