0–1:

• What matters: Finding PMF (product-market-fit)
• Actions: Focus on demand, be manual, do unscalable work, ignore polish.
• Metrics: Conversations/week, conversion rate of good-fit customers.

1–100:

• What matters: Scaling.
• Actions: Build systems, optimize processes, hire, diversify channels.
• Metrics: CAC, LTV, revenue growth, retention curves.

Trap: Using 1–100 tactics (brand building, full automation, complex org charts) before 0–1 will slow you down or kill the company.
