Zero to Network: A Founder's Guide to Building Products People Can't Leave

Every founder starts with the same dream: millions of people using your product, depending on it, telling their friends about it. But the average consumer switches between nine different apps every single day, and most SaaS products lose over 50% of their users within the first three months. The companies that win do not just build features. They build networks.

This book is a practical playbook for founders who want to engineer defensibility, retention, and community into their products from day one. It connects network effects, switching costs, retention mechanics, and community-led growth into a single roadmap that takes you from zero to escape velocity.

Inside, you'll discover:

• The sixteen forces that shape networks and how to use them

• How to solve the cold start problem with atomic networks

• Designing switching costs that create value, not resentment

• Engineering habit-forming products that users depend on daily

• The difference between virality and network effects

• How to build community-led growth that replaces expensive acquisition

• How to layer multiple network effects for compound defensibility

Build a product that users do not just try but genuinely cannot imagine living without.
