Growth inflections

Lenny Rachitsky surveys growth inflection stories from roughly two dozen well-known products to find what tends to precede sudden growth jumps. He sorts them into three groups: product improvements, external events that need no product change, and companies doubling down on their primary growth engine. His core argument is that durable growth requires all three over time, though a single moment often sparks it.

01Key takeaways

• Most growth inflections in the study were triggered by a meaningful product improvement, often a single key feature or capability.
• Some inflections came from external events like press coverage, celebrity moments, or partnerships, with no product change at all.
• Durable inflections often come from investing harder in the primary growth engine, such as SEO, virality, or channel partnerships.
• Long-term sustainable growth needs ongoing product improvements, events that spread the word, and a well-run growth engine together.
• Marketplaces tend to see their biggest inflections from improving supply quality and quantity rather than demand-side changes.
