Raising product growth metrics across the funnel — acquisition to retention — with A/B tests and data.
Growth Hacking combines creative experimentation with data analysis to rapidly improve the core growth metrics of products and services. It spans the entire AAARRR funnel — from forming hypotheses and running A/B tests to designing retention strategies and viral loops. Beyond simple traffic acquisition, it encompasses product-led growth strategies where the product itself drives user acquisition, activation, and expansion revenue.
5-stage experimentation maturity model (Beginner→Transformative) with 4-dimension assessment (Strategy, People, Process, Data) directly used for L2-L6 checklist behavior criteria design
Fundamental→Generalist→Specialist 3-tier with 15 skill categories provides structural basis for L1-L3 (foundation)→L4-L5 (generalist)→L6-L7 (specialist) level boundaries
AAARRR 6-stage funnel defines the scope of funnel coverage at each level (L1: single metric→L4: full funnel→L7: funnel redesign)
Systematic literature review redefining growth hacking as a universal business model scaling methodology beyond startups, providing evidence base for L4-L7 strategic behavior checklist criteria
Canonical textbook by growth hacking originator Sean Ellis; Growth Team building→High Tempo Testing→AAARRR playbook sequence provides authoritative context for entire L1-L7 level design
