I find where your business is losing money - and build the thing that fixes it.

Consultants hand you a report and leave. I'm an engineer: I find the problem in your own numbers, then build the fix myself. Twelve years across e-commerce, marketplaces and manufacturing.

AI Business Review

Where your money and your time are actually going, and the one thing worth fixing first.

  • Where revenue is leaking or being left on the table, with a yearly figure
  • What each problem costs to fix, and in what order
  • What you should not spend money on - usually the most valuable page
  • A written report you keep, whether or not we work together afterwards

If there's something worth building, I build it. Scope and price come out of the review, not out of guesswork. Ongoing support is a separate monthly retainer with capped hours, so you always know what it costs.

What that has looked like

DTC supplements brand

The owner didn't know which products were actually driving revenue - nobody was measuring it. I built the tracking, restructured the catalogue into bundles based on what the data showed, then added a subscription tier so repeat customers reorder without being sold to again.

Fashion rental marketplace

They wanted to test selling partner products alongside rentals. I built the system that reads every partner catalogue, describes each product automatically and matches it to the right customer. We piloted on one product category out of twelve.

E-commerce platform

Paying $2,500 a month to keep the site running, with everyone trying to fix the obvious causes. The real one was architectural. I found it, fixed it, hardened the site after a live attack, and made it measurably faster.

How it works

  1. A call, 30 minutes, free

    You tell me what's bothering you. I tell you honestly whether I'm the right person. If I'm not, I'll say so on that call.

  2. The review, five working days

    I look at your numbers, your systems and how the work actually gets done. You get a written report with figures you can check. The five days start once I have access, not when you pay.

  3. You decide

    Fix it yourself, hand it to your team, or have me build it. The report is yours either way.

Is this for you?

This is for you if

  • you run an online store or a product business turning over roughly $100K-5M a year
  • you suspect money is leaking somewhere but can't point at where
  • you can get me access to your numbers within a couple of days

This is not for you if

  • you already know exactly what you want built - hire a developer, it will be cheaper
  • you are pre-revenue - there is nothing to find yet
  • you want a second opinion to overrule your own team

Why the review is paid

I charge for the review so my answer isn't shaped by what I'd like to build for you afterwards.

Agencies review for free and always find a reason to sell you a big project. I'd rather be paid for an honest answer - including when the honest answer is "don't spend the money."

You probably are. Five working days to find out where.
