A senior growth adviser and trusted growth partner to consumer founders.
I help founder-led consumer businesses find the real growth constraint, then build one clear plan across brand, product, acquisition, retention, data and economics. 20 years inside these businesses, from launch to exit.
Four steps that make a blurry growth picture clear.
Diagnose the constraint
Read the cohorts, the economics and the channel mix, and name the one thing holding growth back.
Connect the growth system
Brand, product, acquisition, retention and data working as one system rather than separate projects.
Create the organising narrative
One story of where growth comes from, so the whole company gets behind one plan.
Support rollout
Stay close while the plan lands, coaching the people who will run it after I have gone.
RARE BREADTH AND DEPTH OF GROWTH ABILITY
I have spent over 20 years in the weeds of UK consumer growth, supporting pioneering founders.
01
Data & unit economics
Too many businesses don't have the data set-up correctly to confidently grow net new sales and increase customer value.
02
Technical adaptability
I have always used first principles irrespective of the technical foundations and ways of working. The need for growth and product teams to work as partners stays the same.
03
Brand instinct
Growth suffers when it hasn't locked down positioning, product experience and a consistent narrative that drives visibility, preference and advocacy.
04
Performance
Once the foundations are in place, build acquisition and lifecycle engines that scale at an incremental CAC the business can actually afford. Performance tactics alone are never the solution.
05
Judgement
Martech and AI can speed up the mechanical work but experienced judgement and crystalised intelligence is the difference between ok and great.

Acquisition & Retention
Churn
cut by fixing product availability
Saw that cheaper acquisition was hurting growth, as low-quality customers failed to retain. Fixed product availability and experience, which cut churn and the volume of new customers the business needed.

Repositioned around customer segmentation, proposition and retention. £14m Series B.
“Jamie was hired after Series A when topline growth looked great but we had a churn problem. His relentless focus on customer insights and segmentation meant we improved LTV:CAC significantly and secured a £14m Series B to fund the next stage of growth. - Ben Pugh, CEO and Founder”
Fluent in the numbers
Companies often need help interpreting and acting on the data that drives growth.
I interrogate the cohorts, the unit economics and the channel mix, and triangulate the influences on incrementality. We get the confidence the plan needs and commit to it.
Partial validation breeds false confidence. The discipline is knowing which numbers to trust.
How engagements work
Find the constraint. Then choose how far to take it.
Every engagement starts the same way, with The Growth Constraint: a short, fixed diagnostic that finds the one thing holding growth back. From there you decide how far to take it. Deliver the fix as a defined project, embed a growth lead for a stretch, or keep me on lightly to steer the plan. Advisory also stands on its own.
START HERE
The Growth Constraint
A short, fixed-scope diagnostic that finds the one real constraint on growth, then the two or three moves that matter most. I immerse in your data, customers and team, then hand back a clear read: the right goal for this stage, the organising strategy to hit it, and the prioritised, sequenced moves. You keep the output whether or not we carry on.
Format: Fixed scope · 3 to 4 weeks · around 6 to 8 hours of your time · one artefact you own
Best for: Founders at a growth crossroads who want to know the real problem before paying for the fix
Add-on: Continue with light retained advisory to keep the plan on track
A defined brief with a clear start and finish. Value proposition, go-to-market, brand fundamentals, channel plan, delivered and handed over.
Best for: A specific, high-value job. A launch, a reposition, a channel reset.
B
Embedded growth lead
A growth lead inside the team for a stretch, setting direction, building the engine and coaching the people who will run it after.
Best for: Scale-ups that need a growth leader for a period, without a permanent hire.
C
Retained advisory
A senior second opinion on tap. Strategy reviews, a sounding board for your growth lead, and the awkward question someone needs to ask.
Best for: A senior second opinion for founders and MDs who want experienced judgement on tap. Take it on its own, or as a light continuation after The Growth Constraint.

My job, stripped back, is to take something tangled and hand you back a clear path to growth. I've done it as an early employee at LOVEFiLM, as employee number three at Zoopla, as a CMO and VP, and increasingly as the outside adviser founders call when the growth picture has gone fuzzy.
Brand people think I am a performance person, performance people think I am a brand person, and the finance team are pleasantly surprised I can read a cohort table. That overlap is the whole point. It is where the compounding happens, and it is worth more as AI does more of the doing.
Away from growth strategy you'll find me coaching youth sport, trying to get my handicap down or being a wholly unconvincing rock guitarist.

Got a curve that should be bending?
Tell me where growth has stalled. I will tell you, honestly, whether I am the right person to help, and where the constraint probably is.
