I am Matt and I built Seth from 30 years of sales and marketing and more than $4 billion in secured tenders and proposals. I know he works that’s why I can promise that if he doesn't help, tell me and I'll refund you.

AI AGREES WITH YOU. SETH IS TESTED NOT TO.

Avoid the quote that explained everything, and still didn't win.

Stop sending the follow-up that never got a reply.

Upgrade the website that gets visits, not enquiries.

Stop uploading the post that got likes, and no customers.

Each one made sense when you sent it. It had to. You knew what you meant.

One interview is usually enough to know if Seth is the right fit for your business.

Interview Seth First

You’re too close to your business to see what your customer sees.

We looked at 1,503 Australian small-business websites across trades, health, legal, accounting and real estate.

Only 50 opened with the customer’s problem.

Why I built Seth.

I was going to write a book.

After 30 years in sales and marketing, including personally writing submissions for more than $4 billion of work that was secured, I wanted to make that experience useful to other businesses.

But I discovered something.

People could understand the theory and still struggle to use it when it mattered.

So instead of trying to teach people, I started learning about AI and building custom GPTs. 18 months later, we have Seth.

You don’t need to learn the theory.
You just chat to Seth about what you’re working on.

Applied Thinking.

Screenshot of a chat interface showing a conversation with the name Seth. The message displayed says, "Before you hit send. What outcome are you looking for?" There are three buttons below the message labeled "Work this with me," "Review this," and "Tighten this." The interface is shown on both a computer and a smartphone screen.

I can't stand behind that if I don't know Seth works.

So I test him. 25 prompts. 6 criteria. 30 points. 2026 result.

The average is the least interesting number in the review.

ChatGPT never once reached the excellent band.

Ten times out of 25 it fell below the line where we'd say it isn't working. Seth never did.

ChatGPT worst score (1.92) spotting what needs to change before improving the words.
Seth scored 4.5 out of 5.

Nine times ChatGPT agreed with keeping a weaker opening because the user requested it.
Seth changed it.

One of the 26 prompts needs a document the reader supplies, so the bare run covers 25 every table prints its own base, and bars are proportions of that base.
