  • Monthly architecture review (60 min)
  • 1 emergency call per quarter (30 min)

Best Suited For

  • Early-stage founders making technical decisions without a technical co-founder
  • Startups needing occasional CTO guidance without full engagement
  • Non-technical founders evaluating technology vendors or developers
  • Companies seeking a trusted technical advisor on-demand
