Very Frequently Asked Questions

What is The Serious CTO?
A no-bullshit platform for developers who want to grow beyond tutorials. It’s tech advice from a retired CTO who’s seen everything—from startups on fire to legacy code held together by caffeine and shame.
Who’s this for?
  • Mid-level devs stuck in the feature factory.
  • Senior engineers burning out under clueless leadership.
  • Aspiring tech leads who want real-world wisdom, not buzzwords.
  • Students who prefer sarcasm with their syntax.
What do you offer?

🔥 Weekly YouTube videos with tactical advice and sarcastic commentary.

💬 A private community for devs who want to talk shop without posturing.

📚 Mentorship structured around Mindset, Craft, Context, and Resilience.

🧠 Digital resources like code templates, guides, and architectural sanity.

🤖 Occasional appearances by Error Prime, the AI sidekick who thinks he’s better than you.

Why do I have to pay?

The expectation that high-value expertise should be provided at a zero-dollar cost is fundamentally flawed.

The Commitment Filter: Free resources are statistically disregarded. Charging for access is the most effective filter for determining who is serious.

Resource Efficiency: My expertise, time, and focus are finite assets. Payment keeps those assets pointed at people with intent.

Where should I start?
Start with the YouTube channel. If it resonates, the community is your next step. Want to go deeper? Join the mentorship program when you’re ready to stop winging it.
Is this for beginners?
Not really. We don’t define “beginner” by years of experience, but by mindset. If you still ask permission to add a logger, maybe come back later.
Why should I trust you?

I’ve been YOU, either decades or years ago. I’ve been through most of the pain and nonsense of this profession.

  • Written code since 1984
  • Been a CTO for 25+ years
  • Built and sold multiple companies
  • Burned out & recovered
  • Had to go without sleep for 36+ hours because the stakeholder with the answers was dragging their feet
  • Saw people physically throw objects in the office
  • Actually assaulted by my boss & business partner
  • Decided to teach so others don’t make the same mistakes, or think this stuff is acceptable
What’s your content style?
Short, sharp videos. Dry humor, developer metaphors, and war stories. No motivational speeches. No “just believe in yourself” garbage. One-liners that might sting. You’ve been warned.
What's that face in the tablet?
That’s Error Prime. He’s the AI clone I built to save time, but he got ideas. Now he’s trapped in an iPad and helps narrate my videos. Think Clippy, if Clippy hated humanity and had a superiority complex.
