How they build

Brett Williams avatarBrett Williams

  • Productize a service with a flat monthly price instead of quoting projects.
  • When demand outgrows capacity, raise prices rather than hire.
  • Stay small and keep the margins.

Corey Haines avatarCorey Haines

  • Marketing something that solves a real problem is a service, not a necessary evil.
  • Learning in public is one of the most generous things you can do.
  • Turn your expertise into frameworks and SOPs — and now into skills AI agents can run.
  • Marketers who learn a little technical skill get outsized leverage.
