    Product-channel fit for growth ↗

    Channels have native rules that shape the products able to grow through them; SEO cannot be bolted onto a product that produces nothing searchers want.

  2. Viral marketing 101

    Growth loops are the new funnels ↗

    Funnels spend an input; loops reinvest an output into the next cycle. Growth strategy improves when the compounding system is modeled directly.

  3. Viral marketing 101

    The universal growth loop ↗

    Every growth system can be expressed as an input, action, output and reinvestment step, making missing compounding links easier to see.

    Building a growth process: first tactics second ↗
