A hundred initiatives will cross your desk this year, each with a business case attached. Your business has the capacity to do five of them well.

The thinking

Most teams are solving the wrong problem well. AI enhances that ability.

I focus on three questions, asked in order, so we can check the diagnosis before you spend on the cure.

01

Why it is that smart businesses so often focus on solving the wrong problems.

02

Why AI makes that failing so much more costly, and, correspondingly, why smarter diagnosis makes decisions cheaper.

03

How leaders build the discipline of diagnosing before accelerating into their own and their teams’ decision-making.

A consultant, or an agency

An agency sells you hours. I sell you the decision about where to use them.

Most brands at this size already have several agencies, and the agencies are usually fine. What’s missing is someone in the room who doesn’t earn more when the scope grows. I don’t sell software, I don’t run a delivery team that needs feeding, and the advisory is designed to be stopped rather than renewed.

Twenty years on both sides, running eCommerce P&Ls at brands like Missguided and building an agency that sold to Brainlabs, is how I know where each side hides its problems.

How I work, and what it costs

Proof

The brief was not the problem.

01Board nervous about a £300,000-plus replatform decision, three agencies pitching three different answers. Led discovery and governance.+8% conversion · +12% AOV
02A fashion brand asking about site speed and an app contract. The real problem was simpler: they’d outgrown their vendors and were renting capability they should own.$600k a year eliminated
03Major transformation for an eight-figure consumer brand, where the product data underneath couldn’t carry the ambition. The harder play was the right one.Zero trading days lost

The first call

Thirty minutes is enough to know.

There won’t be a pitch. Just a conversation about where you are and what needs to happen next, and we can see if I’m the right person for it.
