The CTO Substack

About the Substack

Built by a CTO, Etienne de Bruin. For those CTOs still in love with the craft. This weekly email is for tech leaders navigating complexity, AI disruption, and the loneliness of the seat.

Free Subscription Benefits

  • Occasional public posts

Paid Subcription Benefits

  • Concrete recommendations, not just frameworks: What Iโ€™d actually do given real constraints around team size, budget, and politics.
  • Decision-ready thinking you can reuse: memos, scripts, and explanations you can lift directly into emails, docs, or exec conversations.
  • The parts I donโ€™t publish publicly: opinionated takes and failure modes that are too specific to be useful without context.

Paid Subscription Plans

  • $150 a year
  • $15 a month
