growth-model
Help users transition from linear funnel thinking to a loop-based growth model that identifies and optimizes the core engines of their business.
Why this skill is useful
Provides a structured approach to building a growth model with specific frameworks and mathematical representations that the AI wouldn't generate on its own.

What this skill does
Building a Sustainable Growth Model Move beyond linear funnels to build compounding loops that drive scalable, long-term product growth. Help the user with building a sustainable growth model using insights from 16 guests and posts across Lenny's Podcast and Newsletter. How to Help 1. Audit current mechanics - Assist the user in identifying whether their current growth is driven by SEO, paid ads, sales, or virality based on product characteristics. 2. Visualize the model - Guide the user to map out their growth as a system of interconnected, reinforcing loops rather than a one-way funnel. 3. Quantify the loops - Help the user build a mathematical representation of their growth variables in a spreadsheet to stress-test their assumptions. 4. Identify constraints - Analyze where growth is stalling by diagnosing failure points in the user journey from acquisition to retention. Core Principles Loops over funnels Shishir Mehrotra: "But I highly encourage drawing a diagram like this for your business. I'll flash it up on screen for a second and I'll describe it, but this is what the diagram looks like, black loop, blue loop, and it's basically the two different ways that our product spreads. The Black Loop is someone comes in, they make a doc, they share with a group of people, some subset of the people turn around and make another doc, and the process repeats itself over and over again." Visualize growth as recurring loops where the output of one cycle becomes the input for the next, creating organic mechanisms for scaling. Mathematical reconciliation Dan Hockenmaier: "And that's how I think about a growth model, so the analytical representation of how the business grows and it's typically built in a spreadsheet which has a really nice feature of being very hard to fake. …
