AARRR (Pirate Metrics)

Dave McClure's framework tracks: Acquisition (users find you), Activation (great first experience), Retention (users come back), Revenue (monetization), Referral (users tell others). Optimize each stage systematically.

North Star Metric

Single metric that best captures core value delivered to customers. Examples: Airbnb (nights booked), Spotify (time listening), Amplitude (weekly querying users). Align entire growth team around moving this metric.

ICE Score Framework

Prioritize experiments by Impact (1-10), Confidence (1-10), Ease (1-10). Calculate average score to rank experiments. Run highest-scoring tests first to maximize learning velocity and results.

Bullseye Framework

Gabriel Weinberg's approach tests all 19 traction channels, identifies the bullseye (best channel), and focuses resources there. Prevents premature optimization and ensures channel-product fit.

Growth Loops vs. Funnels

Replace linear funnels with self-reinforcing loops where outputs become inputs. Content loop: users → content → SEO → more users. Viral loop: users → invites → new users → more invites. Loops scale indefinitely.

What is growth hacking?

Growth hacking is a data-driven marketing approach focused on rapid experimentation across marketing channels to identify the most effective ways to grow a business. It emphasizes scalable, repeatable tactics that prioritize user acquisition, activation, retention, revenue, and referral (AARRR framework).

How much do growth hacking companies charge?

Growth hacking agencies typically charge $5,000-$30,000/month for retainer services. Project-based engagements range from $10,000-$100,000. Some agencies work on performance-based models (10-30% of revenue increase). Costs vary based on company size, market, and scope of experimentation.

What results can I expect from growth hacking?

Typical results include 20-50% increase in user acquisition, 15-40% improvement in conversion rates, 25-60% reduction in customer acquisition costs, and 30-100%+ growth in key metrics within 6-12 months. Results depend on product-market fit, budget, and execution quality.

How is growth hacking different from traditional marketing?

Growth hacking emphasizes rapid experimentation, data-driven decisions, product-led growth, viral mechanics, and automation. Traditional marketing focuses on brand building, long-term campaigns, and established channels. Growth hacking prioritizes scalable tactics with measurable ROI over brand awareness.

Do I need a growth hacking agency or can I do it in-house?

In-house works if you have dedicated growth talent, technical resources, and experimentation culture. Agencies provide expertise, proven frameworks, and faster results. Many companies start with agencies to build initial momentum, then transition to in-house teams once processes are established.

What industries benefit most from growth hacking?

SaaS, mobile apps, e-commerce, marketplaces, and consumer tech see strongest results due to digital distribution and measurable metrics. However, growth hacking principles apply to any business with online customer acquisition channels and ability to track user behavior data.

How many experiments should we run monthly?

High-velocity growth teams run 10-20 experiments monthly across acquisition, activation, retention, and monetization. Start with 5-10 monthly if new to growth hacking. Focus on experiment quality and learnings over sheer volume. One breakthrough insight can drive 10x more impact than ten mediocre tests.

What's the difference between growth hacking and SEO?

SEO is one channel within growth hacking. Growth hacking encompasses all growth channels (paid, viral, content, product, partnerships) and optimization across the entire user lifecycle. Growth hackers use SEO as one of many levers, while SEO specialists focus exclusively on search optimization.
