Growth Loop
A self-reinforcing cycle where each cohort of users generates inputs (data, content, referrals) that attract the next cohort, creating compounding growth.
Growth loops replace the traditional marketing funnel with a circular model. Instead of a linear path (acquire -> activate -> retain -> monetize), loops create systems where output becomes input: users generate content that attracts new users who generate more content. The most powerful loops compound — each cycle is more efficient than the last.
AI amplifies growth loops in three ways. First, data network effects: each user's behavior trains models that make the product better for everyone, creating a defensible moat. Second, AI-generated content loops: user activity generates SEO-optimized content that drives organic traffic. Third, AI-enhanced viral loops: LLMs create personalized shareable artifacts from user activity, each one a potential acquisition touchpoint.
The key to designing effective growth loops is identifying your product's natural compounding mechanism. For B2B SaaS, it might be templates or workflows that users share. For consumer products, it might be AI-generated summaries or insights that users post on social media. The best loops feel like product features, not growth hacks — users participate because the loop creates genuine value for them.

Viral Coefficient (K-Factor)
The average number of new users each existing user brings to the product, where a K-factor above 1.0 indicates self-sustaining viral growth.
Activation Rate
The percentage of new signups who complete a key action (the 'aha moment') that correlates with long-term retention and product value realization.
Product-Led Growth (PLG)
A go-to-market strategy where the product itself drives acquisition, activation, and expansion through self-serve experiences rather than sales-led motions.
Churn
The rate at which customers stop using or paying for a product over a given period, typically measured as monthly or annual churn percentage.
Net Revenue Retention (NRR)
The percentage of recurring revenue retained from existing customers over a period, including expansion, contraction, and churn — where 100%+ indicates growth without new customers.
Customer Acquisition Cost (CAC)
The total cost of acquiring a new customer, calculated by dividing all sales and marketing spend by the number of new customers acquired in a given period.
