Word of Mouth Growth: Successful products often grow through organic word of mouth rather than marketing.

Feedback Loops: Establish tight loops for continuous user feedback to improve the product.
Fanatical Attention: Founders should be deeply engaged with user feedback and product quality.
Measuring Success: Focus on metrics that indicate growth and user engagement, not just registrations.
