[ 2012 TO 2026 · 60 case studies ]

The diagnosis is the product.

These 60 case studies explain what needed fixing, what I did and what happened.

DISCLOSURE

You shouldn't care about case studies. Past performance is no indication of future results. What carries is how the diagnosis gets done when money and reputation are on the line.

What I can guarantee is what I control: my output, and my system, people, product, process, followed closely. It gets results most of the time. Nobody can guarantee you the results themselves, me included. That's what the test budget is for. We take a set amount of money, break it into pieces, run a set number of tests, and treat the whole run as live market research. Who's buying, who isn't, which creative structures work, which headlines work, and what the next round needs to cost. I can't promise you 10x in a testing round. I can promise you'll learn something and you'll be closer than you were before.

Customers and markets

Your dashboard says the Tuesday ad sold them. It didn't.

They first saw your ad three weeks ago. Your report only credits the last one they clicked.

If your gut has never been wrong, you don't need me.

Sales and growth

I read your one-star reviews before I write your ads.

Never wondered if you're leaving money on the table? Then I'm not your guy.

Operations and delivery

Your next hire should inherit a system they can run.

I left a 13-person software company with a working sales pipeline, deal notes and written instructions for the next operator.

If nobody on your team will own the handover, I'm not your guy.

AI and knowledge

I build the smallest thing that solves your problem. Then I ship it.

It's easy to over-engineer something that never ships. I've watched a lot of AI projects stop right there.

If you want the fanciest stack on the market, I'm not your guy.
