Sean Ellis pioneered the discipline of growth marketing as we know it today. His work at Dropbox, LogMeIn, and Eventbrite established the playbook for high-tempo experimentation. Reading Hacking Growth and following his ICE prioritisation framework became the foundation of how I structure every growth program I lead. His insistence on the 'must-have' survey as a product-market fit signal still informs my early-stage work with founders.
Key lessons
- Treat growth as a structured, repeatable process — not a series of clever tactics.
- Measure product-market fit with the 40% 'very disappointed' threshold before investing in scale.
- Use ICE scoring to prioritise experiments objectively across the full funnel.
- Build cross-functional growth teams with shared metrics, not siloed departments.
Impact on my career
Sean's frameworks are the operating system behind every growth program I run. The high-tempo testing model is how I structure weekly growth meetings with the startups I advise.
