Your shop can sell more. I find out what's holding it back, and I fix it.

Visitors arrive, too few buy. I find the places where your shop loses buyers and rebuild them.

Free. I look at your shop first.

Companies I have worked for

Five situations where I come in.

The shop sells less than it should.

Visitors arrive, too few buy, even after the relaunch, and nobody can say exactly why. I go through the buying process the way your customers do, put the numbers next to it and find where buyers drop off. Then I change it.

Your team can't keep up.

The idea list keeps growing and only a fraction ships. I take your list, rank it with you by revenue impact and build it, one person, no briefing loops. You decide, your team stays on day-to-day work. The first change goes live in week 1.

The e-commerce role is open.

Finding and onboarding someone takes months. I usually start next week, keep the shop and the team moving and hand over to your new hire when they arrive. A short update from me every working day. After that I stay if you want me to.

Agencies didn't move much.

Reports and meetings, and revenue barely changed. Nobody sits between us. You talk directly to the person who plans and builds.

The shop is considered fully tested.

Tests check ideas somebody already had. I start earlier: which products carry the revenue, and do range and prices fit them?

Your situation isn't listed?

Smaller shops too. Tell me about it, 15 minutes on the phone.
