Build your brand B.R.A.I.N.™
Scale everywhere.

Your brain knows who you are, who buys and why. Your verbal, visual and sonic brand identity makes you unmistakable. One engine takes it everywhere.

For e-commerce brands, creators and service businesses. Works in Claude and Codex.

Start here

Who are you? Here’s how it works for you.

Your look, your voice, your sound. Every post.

Your B.R.A.I.N.™ knows
  • Your point of view and your origin story
  • Your audience: who watches, what they ask, the words they use
  • Every on-screen look, every hook, every sign-off
  • What you offer: courses, products, brand deals
Your customers could look like
The busy parentThe total beginnerThe ready-to-commitThe supplement brand

Every product. Every customer. Every campaign idea.

Your B.R.A.I.N.™ knows
  • Every product, even hundreds, and who each one is for
  • What’s actually selling, and which ads really work
  • The real moments your customers need you
  • Your year of campaign ideas, timed to demand
Your customers could look like
The weekend walkerThe commuterThe first big hikeThe outdoorsy one’s partner

Who hires you. And why they say yes.

Your B.R.A.I.N.™ knows
  • Every service, packaged clearly, with who it’s for
  • Who hires you, and the moments they pick up the phone
  • Your reviews and results, sorted by who they persuade
  • How your whole team sounds, in every proposal and post
Your customers could look like
The injured runnerThe office workerThe over 40sThe first visit nerves

Run an agency? B.R.A.I.N.™ for Agencies comes later.

Why it matters

AI with no brain sounds like everyone.

Most people add AI before they teach it who they are. The words drift, the voice changes from channel to channel, and every new tool makes another version of the brand.

A deep brand identity, built from real research, is what stops AI content feeling, looking and sounding like AI. It sounds like you.

You said you’d go anyway. Now you can. Taped seams, packs into its own pocket, and it’s on the next hill whether the forecast likes it or not.

  • Built from your customers’ own words
  • Real moments on wet walks
  • Your voice, edge 7 out of 10
What you build

One brain. Three ways to be unmistakable. One engine.

1

The brain

Who you are, who buys and why. The engine researches your market for you, then builds the strategy with you: your gap, your customers, why they really buy, and your campaign ideas.

2

Your brand identity

Verbal: how you talk. Visual: how you look. Sonic: how you sound. Locked, written down properly, and ready for every AI tool you use.

3

One engine, everywhere

The Distribution Engine turns your brain into finished posts, videos and ads for every channel, in a ready-to-post folder.

Become a Marketing Engineer

We don’t need more marketers. We need Marketing Engineers.

AI has changed, well, everything. A Marketing Engineer trains AI the way you would train a brilliant new hire: who the brand is, who buys, why they buy, and how it talks, looks and sounds.

What is a marketing engineer? Read the full answer

“This isn’t about doing everything faster. It’s about doing everything 1 million times better.”

I could have kept all of this locked inside an agency. Instead I’m teaching you to build your own, so you can take the stress and noise out of running your business and focus on what moves it.

The questions people ask most, answered in a sentence or two.

What is Marketing Engineers?

Marketing Engineers is the do-it-yourself home of B.R.A.I.N.™, by Mary-Anne Da’Marzo, The Marketing Engineer. You build your own brand B.R.A.I.N.™, so every AI tool knows your brand as well as you do.

What is a brand B.R.A.I.N.™?

It’s brand guidelines that AI can actually use. It knows who you are, who buys and why, and how you talk, look and sound, all researched from your real market.

Which AI tools does it work with?

Claude and Codex. You add one custom connector, and behind it sits a full suite of software, personalised to you. Then say “build my brain” and it walks you through.

Do I need to be technical?

No. If you can send an email, you can do this: it asks one question at a time and shows you an example answer.
