The Library

Everything running a software business asks of you and none of it is code: onboarding that activates, churn you can actually see coming, marketing with no budget, SEO that finds buyers, and the AI-plus-Ahrefs workflow for writing the blog that feeds it. One new playbook a week, plus the whole archive from day one.

$9/ month · cancel any time
  • A new playbook every week — onboarding, churn, growth, SEO, content
  • The full back catalogue the moment you join, not drip-fed

  • The research shelf — real papers, decoded, on learning and on LLMs
  • One email when a new one lands, off by default in one click
  • Cancel any time; you keep reading to the end of the month
