Growth Hacking
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.

Levels
Level 1
#GrowthMetrics#AAARRR#FunnelBasicsLearning growth metrics and funnel basics, reading existing data.
At this stage, you are newly interested in growth hacking and starting to learn the fundamentals. You can understand what each stage of the AAARRR funnel means and identify key growth metrics. You cannot yet design or run experiments independently, but you can read and interpret existing data at a basic level.
What Comes Next
If you've checked off most of this list, you're ready for the Emerging stage, designing simple experiments and running A/B tests yourself. Kolb(1984)'s Experiential Learning theory suggests running real experiments with actual data and reflecting on results to build practical growth intuition faster than theory alone.
Level 2
#ABTest#ChannelExperiment#DataTrackingDesigning single-variable A/B tests, tracking channel data.
You can design A/B tests targeting a single variable and interpret the results. You track and compare performance data across major acquisition channels and set up event tracking to collect user behavior data. You can repeat simple experiments without guidance, but systematic prioritization of experiments is still challenging.
What Comes Next
If you've checked off most of this list, you're ready for the Emerging+ stage, systematically prioritizing experiments and independently performing conversion optimization. Ericsson(1993)'s Deliberate Practice theory suggests structuring A/B testing and data interpretation into repeated sessions with targeted feedback to sharpen your experiment design skills.
Level 3
#ICEPrioritization#HighTempoTesting#ConversionOptimizePrioritizing with ICE, optimizing conversion in weekly cycles.
You systematically evaluate and prioritize experiment ideas for independent execution. You manage an experiment backlog using ICE (Impact, Confidence, Ease) scoring and plan, execute, and review experiments on a weekly cadence. You perform conversion rate optimization on specific funnel stages and produce consistent experiment outputs.
What Comes Next
If you've checked off most of this list, you're ready for the Managed stage, overseeing the full funnel and designing retention strategies with cross-channel optimization. Vygotsky(1978)'s Zone of Proximal Development suggests taking on conversion optimization challenges just beyond your current ability, with guidance from experienced growth practitioners, to build independent funnel management skill.
Level 4
#FullFunnel#RetentionStrategy#CrossChannelManaging the full AAARRR funnel, designing retention and channel mix.
You understand and manage the funnel as an integrated whole rather than individual stages. You analyze retention curves to build long-term retention strategies and connect data across multiple channels to design optimal channel mixes. You make data-driven decisions in complex situations and report experiment impact in terms of revenue and LTV.
What Comes Next
If you've checked off most of this list, you're ready for the Advanced stage, leading a growth team and spreading experimentation culture across the organization. Bandura(1977)'s Social Learning theory suggests studying how top growth leaders design retention strategies and optimize cross-channel performance, then applying those approaches to your own funnel management.
Level 5
#GrowthTeamLead#ExperimentCulture#ScalableLoopsLeading a growth team, spreading experiment culture, scaling loops.
You lead the composition, goal-setting, and experimentation processes of a growth team. You collaborate with other departments to establish experiment-based decision-making culture across the organization. Beyond individual experiments, you design scalable growth loops and mentor junior growth practitioners. You build systems that manage both experiment velocity and quality.
What Comes Next
If you've checked off most of this list, you're ready for the Transformative stage, designing the organization's growth engine and establishing standards at the industry level. Schön(1983)'s Reflective Practice theory suggests pausing during growth loop design to examine your own reasoning, turning tacit growth expertise into explicit methods you can teach others.
Level 6
#GrowthEngine#PLGStrategy#ExperimentGovernanceBuilding the growth engine, PLG strategy, and experiment governance.
You design the overall growth strategy and experimentation governance for the entire organization. You establish product-led growth strategies where the product itself drives growth, share results at industry conferences, and set benchmarks. You coordinate multiple growth teams and establish organization-wide standards for data infrastructure and experimentation platforms.
What Comes Next
If you've checked off most of this list, you're ready for the Transformative+ stage, pioneering new growth methodologies and contributing to the growth paradigm of the broader industry. Lave & Wenger(1991)'s community of practice model suggests mentoring emerging growth leaders from within professional networks, turning shared experience into lasting industry frameworks.
Level 7
#GrowthFrameworkCreator#CategoryCreation#SeanEllisCreating new methodologies and redefining the industry's paradigm.
You go beyond existing growth hacking methodologies to propose new frameworks or growth paradigms. Through books, lectures, and open-source tools, you influence the broader industry. You execute growth strategies that create entirely new markets or redefine existing categories. You cultivate the next generation of growth leaders.
What Comes Next
If you've checked off most of this list, you're at the forefront of growth hacking, shaping how organizations worldwide approach data-driven growth and experimentation. Mezirow(1991)'s Transformative Learning theory suggests questioning the assumptions behind current growth paradigms and developing new frameworks that change how the field thinks about scalable user acquisition and retention.
