The Road to $100M · Four Growth Frameworks

The frameworks compound; they don't replace each other

The path from $0 to $100M revenue is rarely a single straight line. It is a sequence of phases, each with its own dominant constraint, each requiring different frameworks to navigate. Reforge's Road to $100M essay synthesizes four foundational frameworks — Four Fits, Growth Loops, Growth Models, and Growth Strategy — into a coherent sequence: which framework matters when, and how the frameworks compound rather than replace each other.

Phase 1 — $0 to $1M · Find product-market fit

The first phase is dominated by Market-Product Fit. The question is not "how do we grow?" but "do we have something a real market actually wants?" The frameworks that matter at this stage are diagnostic — Sean Ellis's PMF survey, the Superhuman 40% test, retention curves, qualitative customer interviews. Growth loops and growth models are premature; you don't have anything to loop yet.

Most companies that fail in this phase fail because they accept weak product-market fit signals and try to scale anyway. The discipline is to keep iterating on the product (and sometimes the target market) until the PMF signal is unmistakable.

Phase 2 — $1M to $10M · Find product-channel fit

The dominant question shifts. You have a product the market wants; now you need scalable distribution. This is where the Four Fits framework becomes load-bearing — specifically, Product-Channel Fit and Channel-Model Fit. The product has to be shaped right for the channel you'll use to scale, and the unit economics have to work.

Companies fail in this phase by scaling a product through channels that don't structurally fit. The fix is almost always to reshape the product, not to fight the channel.

Phase 3 — $10M to $100M · Build compounding loops

You have product-market fit and at least one channel that scales. Now the question becomes: can you build self-reinforcing loops that compound, rather than linear funnels that require ever-growing inputs? This is where the Growth Loops framework becomes the dominant lens. Companies that scale linearly past $10M without building loops hit a wall around $30–50M — they've burned out their initial channel and have nothing compounding underneath.

The loop work at this phase is usually amplifying existing weak loops rather than building entirely new ones from scratch.

Phase 4 — $100M+ · Strategic optimization

At $100M+, the dominant question is portfolio. You have multiple channels, multiple loops, multiple product lines. The Growth Strategy framework asks: where do you concentrate investment? Which loops have the most amplification potential? Which markets do you expand into? Which adjacent products do you build?

The frameworks don't go away. Four Fits remains relevant — markets evolve, products evolve, channels saturate, models have to grow up. Growth Loops remain relevant — every loop has cycle time and coefficient that can be improved. Growth Models — the math behind the system — becomes more sophisticated. Growth Strategy is the integrating layer that decides where to deploy.

How the frameworks compound

The key insight from Reforge is that these frameworks don't replace each other across stages. A $50M company still cares about Market-Product Fit (markets evolve, products evolve, fits decay). It still cares about Growth Loops (loops are the engine). What changes is which framework dominates the strategic conversation. The dominant framework at each stage:

• $0–1M: Market-Product Fit. Everything else is premature.
• $1M–10M: Four Fits, especially Product-Channel. Loops are forming.
• $10M–100M: Growth Loops. Four Fits is maintenance, loops are the focus.
• $100M+: Growth Strategy as portfolio. All four frameworks contribute.
