Appearances

• Brian Balfour on Distribution Platforms and Growth — Lenny’s Podcast, ~early 2025

Key themes

• Distribution as the decisive competitive variable, not product quality alone.
• The four-step platform cycle (conditions → moat → open → close) as a recurring historical pattern.
• AI adoption as an organisational system problem, not a tools problem.
