Get the Blind Spot Brain

Free. Takes about a minute. We'll text and email you a code to confirm it's really you.

No spam, no selling your info. By continuing you agree to receive a verification text and email. Message and data rates may apply.

See the difference first

Same question. Two very different answers.

Your AI already gives you good answers. Here's what happens when it knows what I know.

The prompt"I own a roofing company in Dallas. We spend $6,000 a month on Google Ads and our leads dropped 30% this quarter. What should I do?"

Plain AI Example

  1. Review your keywords and add new ones.
  2. Consider increasing your budget to stay competitive.
  3. Improve your website and landing pages.
  4. Invest in SEO and social media.
  5. Ask happy customers for reviews.

Reasonable. Generic. Starts with spending more.

With the Blind Spot Brain Example

  1. Don't touch the budget yet. Spend is the lowest-leverage lever you have.
  2. First, check what "leads" means in that report. If any conversion has a decimal, it isn't counting people.
  3. Then check whether you're still being seen — impression share before clicks, clicks before the landing page.
  4. Pull last quarter's leads that didn't close and ask why. The answer is often the website, not the ads.
  5. Change one thing, measure it against last quarter, and lock the gain before you change the next.

A diagnosis in the right order — before a dollar moves.

What's inside

Everything I teach. Organized so your AI can use it.

LawsHow marketing worksThe rules that hold true whether you like them or not.
PrinciplesHow I make the callThe positions I take with every client that most CMOs don't.
StrategiesWhat to runPlays that work for a pest company and a law firm alike.
Starter promptsWhere to beginThe questions to ask first so you get value on day one.

A few of the laws inside:

Why it's free

So you can vet me the way I vet you.

I only work with certain kinds of businesses — the ones where I know I can move the number that matters. Most CMOs ask you to hire them first and find out how they think later. I'd rather you see exactly how I think before we ever talk.

Use the Brain. Run your own marketing through it. If the way it thinks is the way you want your marketing run, we should talk. If it isn't, you still walk away with something useful — and my time stays with the clients it's built for.

Is the Fractional CMO Brain free?

Yes. You get all 20 marketing laws free, with no credit card. They’re the same laws behind 25+ years of campaigns and $1.5B+ in ad placements since 1999.

What do I get when I install it?

You get an AI that answers your marketing questions the way a seasoned CMO would. Ask about ads, headlines, budgets, tracking, pricing or AI search, and you’ll get the law that applies, what’s breaking it in your business, the fix, and a next step you can take this week.

What can I ask it?

Ask the questions you’d ask a CMO:

  • “My Google Ads get clicks but no leads. Where’s the money leaking?”
  • “Here’s my homepage headline. Which law does it break?”
  • “My report shows 14.62 conversions. Should I trust that number?”
  • “Which number should my marketing check be buying?”
Which AI tools does it work with?

You can use it in Claude, ChatGPT and Gemini. It also works in tools that support Claude-style skills, like Claude Code, Cursor and Gemini CLI. The laws are the same everywhere, so you get the same answers whichever AI you prefer.

What’s the difference between the free Laws edition and the full Brain?

The free Laws edition gives you the 20 rules of how marketing works. The full Brain also gives you the Principles (the order to check things in), the Strategies (plays proven across industries) and the Playbooks (step-by-step run sheets with owners and KPIs). Get it at jrcmo.com/blind-spot-brain.

Does the Brain see or store my business data?

No. The Brain is instructions and reference text that run inside your own AI. It doesn’t collect, store or send anything to JRcmo. Your conversations stay under your AI provider’s own privacy terms.

How do I get updates when new laws are added?

On Claude, the update reaches you automatically. On Gemini, the Gem link stays the same and always has the latest laws. On ChatGPT, upload the newest laws file to your Project whenever a new law is released.

Why isn’t the AI using the Brain in my answers?

Check that it’s switched on. In Claude, go to Customize → Skills, then start a new chat. You can also ask directly: “Use the Fractional CMO Brain to answer this.” Give it your industry, budget and real numbers, and the answers get sharper fast.

Does the Brain replace a CMO?

No. It gives your AI the rules. Applying them to your real numbers, in the right order, is where a session with Josh comes in. You can book a free 2-hour strategy session at jrcmo.com or call 214.466.8332.
