Designing Growth Loops

Viral growth is a learnable science

Nikita Bier: "With certainty, if you're good at your job, you can make an app grow and go viral. Over the years of building all these apps, I've accrued all these growth hacks that still nobody knows about." Develop a library of growth tactics based on platform-specific mechanisms.

LTV unlocks paid loops

Yuriy Timen: "If you have really healthy LTVs, then there is a big opportunity to play paid and lean into paid growth loops." Calculate if single-player LTVs are high enough to support sustainable paid acquisition.

Product-led acquisition has zero marginal cost

Julian Shapiro: "By me trying to use PayPal in its everyday intention, I'm automatically enticing someone else to become a PayPal customer." PLA is the most scalable channel because it's entirely within the company's control.

Innovation over optimization in fast markets

Elena Verna: "I feel like only 30 to 40% of what I've learned transfers here because we need to invest in such bigger bets and innovate and create new growth loops." In fast-moving AI categories, shift from 95% optimization to 95% innovation.

Word-of-mouth requires frequency

Uri Levine: "Word-of-mouth you can only have if you have high frequency of use. If you're using Waze every day, then every day you have an opportunity to tell someone else." Sustainable word-of-mouth is tied to how often users engage with the product.

Map the loops qualitatively and quantitatively

Ben Williams: "Being able to identify the various micro and macro loops, how they're all connected, being able to document them in a qualitative model provides a shared understanding and guides intentional investment."

40-50% organic is the healthy ratio

Gokul Rajaram: "A good metric is that 40 to 50% of your new customers should ideally come from organic channels. If 90% come from paid, at some point the music is going to stop."

Questions to Help Users

• "What's the natural moment when users would want to bring others in?"
• "Does your product become more valuable when more people use it?"
• "What percentage of your growth is organic vs paid?"
• "What's your customer LTV and payback period?"
• "Is there an action users take that automatically exposes your product to others?"
• "Can you identify where users already share your product organically?"

Common Mistakes to Flag

• Paid acquisition on freemium - Consumer subscriptions relying on paid acquisition will predictably fail
• Manufacturing network effects - Network effects are usually inherent; hard to add as an afterthought
• Diversifying too early - Early-stage companies should focus on one working engine
• Single-channel dependency - Late-stage companies with 90%+ reliance on one channel are at extreme risk
• Referral programs without organic WOM - Referrals amplify existing word-of-mouth; they can't create it
