Growth Loops Are the New Funnels — Reforge

Summary

Funnels are one-directional and create silos. Growth loops compound: the output of one cycle becomes the input to the next. Three core problems with funnel thinking:

1. Strategic silos — product, marketing, and monetization strategies get planned independently, causing distribution failures. Channels control the rules, not your product. Monetization model enables or disables certain channels.
2. Functional silos — teams organized by funnel layer (marketing owns acquisition, product owns retention) optimize at each other’s expense.
3. No compounding — funnels have no concept of reinvesting output to feed growth over time.

The fix: model your growth as loops, then translate them into a quantitative growth model to communicate, prioritize, and set goals.

The mental model: if you can’t draw a loop from output back to input, you don’t have a growth engine — you have a leaky bucket.

Relevance

Critical framing for both 01-projects/squarely-puzzles/index and 01-projects/newsletter/index.

For Squarely: what’s the loop? Players solve puzzles -> share results -> new players discover the game -> they solve puzzles. If that loop doesn’t close, growth requires constant paid acquisition.

For the newsletter: readers gain insight -> apply it in their work -> share with peers -> new subscribers. The loop only works if content is share-worthy and practically applicable.

This also connects to 06-reference/concepts/compounding-knowledge — knowledge loops compound the same way growth loops do. Each insight feeds the next.

Open Questions

• What is the primary growth loop for Squarely Puzzles? Is it viral (share-driven) or content-driven (SEO/social)?
• Does the newsletter have a working loop today, or is it still funnel-mode (publish -> hope for subscribers)?
• How do we build the “reinvestment” step into each product — what does the output feed back into?
