A data lead.Without the hire.

I step in as your fractional data and transformation lead. Two to four days a month, or three to six months embedded. I own the call, then I run the delivery.

Fifteen years across finance, government and social housing. Fidelity Investments, Aviva Investors, UBS, the Department for Transport, Monzo.

I · What I Do

Fractional data and transformation leadership. I take the seat, not the sidelines: migrations, new core systems, reporting rebuilds, AI bets, and the operating model around them.

Ten years running this work. I've built the teams, swapped the platforms, and pulled programmes back when leadership and delivery had stopped talking.

I run Stratford Ellis, my consultancy, with a small team behind me. London based, working wherever the work is.

III · For Business

Six ways to bring me in.

A system to pick, a migration that won't add up, numbers that don't agree, an AI bet to size.

The Engagements

Pick the one that fits where you're stuck.

Outcome

The Kickstart, a fixed-scope reset
When
The programme has stalled.
What
Five to ten days to settle the open questions and reset the plan.

The Briefing, strategic briefings
When
The team can't agree what the problem is.
What
Focused sessions on one data, systems or operations question.
Outcome
Common ground and clear next steps.
The Delivery Diagnosis
When
You want an outside read before the next move.
What
Fixed-price review of systems, data and delivery. Plain-language report in five days. No vendor agenda.
Outcome
What to fix, in order.
The Data Audit
When
You can't trust the numbers running the business.
What
What you hold, where it lives, who owns it, whether it stands up.
Outcome
A report and a fix list.

VI · What People Say

Words from the room.

A handful of notes from leaders, founders and chairs I've worked alongside.

Barbs walked into a programme that had been stuck for nine months and had us all reading off the same page inside a fortnight. The plan we left with was the one we actually ran.
Helena Marsh
COOFolio & Field
She tells you what she thinks. No fluff, no vendor agenda. Our board got a read on our data we could finally act on, and a short list of fixes we could start on Monday.
James Okafor
ChairNorthstone Group
Having Barbs in the room changed how we made the call. She knew the context from month two and saved us from at least one expensive mistake on the systems side.
