• Push: You try to convince customers to want what you have. Feels uphill.
• Pull: Customers are already prioritizing the goal you help with and are eager to engage. Feels like they’re pulling your solution out of your hands.
• Bottleneck principle: The first and most critical bottleneck in 0–1 is pull. Until you find it, scaling is impossible.
• Practical takeaway:
  • Stop over-optimizing your supply before finding pull.
  • Once pull exists, your roadmap and marketing become obvious — because demand is shaping them.
