Phenom Digital — senior growth & demand generation

Growth, proven in the boardroom and the venture.

We help founders, marketing leaders and venture builders turn marketing spend into predictable revenue — a senior growth partner who builds the system beneath the growth, not another agency running campaigns.

The problem we solve

You don’t have a channel problem. You have a system problem.

Spend rises but CAC creeps. Reporting takes weeks and still doesn’t answer “is this working?”. The team is busy but growth has plateaued. You need senior judgement and an operating system beneath the activity — not more activity.

How we work

One operating rhythm, four moving parts.

01

Strategy

Diagnose, prioritise, set a measurable growth plan.

02

Execution

Build and run the channels that move the plan.

03

Measurement

A single view of CAC, payback and pipeline — in under 24 hours.

04

Optimisation

A disciplined test-and-learn engine. Only winning work scales.

Who you’ll work with

A senior operator in the room — not a name on a pitch deck.

You get the senior operator who builds the system — in the room and on the work — not a name on a pitch deck who hands you to a junior team. Every engagement is led personally, with enterprise rigour and venture pace.

The leaders who’ve worked alongside James.

I had the privilege of managing James at Trendwatching, and I can honestly say he was one of the most unique talents I’ve had the pleasure of working with and an absolute joy to have on the team. James led digital campaigns and growth initiatives across marketing, CRM, paid media, and digital strategy with a rare blend of creativity and rigour. He didn’t just execute: he elevated everything he touched, bringing fresh thinking and real results to every project. If you’re looking for someone who will make your team both better and brighter, look no further. I’d recommend James without a second thought.
Gillian HarrisMarketing Leader
I’ve had the pleasure of working closely with James, a highly skilled Growth Marketing Lead who consistently drives impact across digital campaigns and growth initiatives. James brings a strong strategic mindset combined with hands-on execution across marketing, paid media, and digital strategy. He has a clear ability to connect the dots between data, audience insights, and creative delivery, ensuring campaigns are not only well-crafted but also performance-driven. What sets James apart is his ability to lead end-to-end digital initiatives, from shaping the strategy to optimizing performance across channels. He is highly collaborative, brings clarity to complex topics, and continuously pushes for smarter, more effective ways of working. I would highly recommend James to anyone looking for a results-driven digital leader who can accelerate growth and elevate campaign impact.
Kallianna SigalaMarketing & Communications, Unilever
I had the privilege of working with James on a large-scale B2B digital marketing project, reporting directly to him in his role as Growth Marketing Lead. James is a true expert in digital growth marketing. He brings a proactive approach and consistently delivers results that make a real difference. He is always going the extra mile to achieve the best possible outcomes. James has a real talent for influencing senior stakeholders through clear, compelling use of data and analytics. He made a significant contribution to optimising conversion journeys across our campaign landing pages. As a project lead, James is approachable, positive, and genuinely supportive, always ready with encouragement when it’s needed. He remains calm and composed under pressure, which had a hugely positive effect on our team’s confidence and morale. He strikes just the right balance between being a fair and respectful leader and a highly experienced digital marketing professional. I wouldn’t hesitate to work with James again and would highly recommend him to anyone looking for a driven, knowledgeable, and all-round brilliant addition to their team.
Angela BraunSenior Digital Content Manager
I’ve had the pleasure of working with James, who joined as a Growth Marketing Lead but quickly proved to be much more. In a lean team setup, he stepped beyond his role, taking on broader responsibilities with ease and impact. He’s crafted digital marketing strategies that deliver results, and played a key role as a project manager for seamless, incident-free Ecomm and website launches across multiple markets. What really sets him apart, though, is his ability to build trust with people, and bring them along the journey with him. A true asset to any digital team.
Bulbul PandyaHead of Product · Ex-Unilever & Ex-McKinsey
James is an absolute pleasure to work with and a true asset to the team. A driven, dedicated and strategic marketer, he has excelled in leading the growth and performance marketing for Unilever Professional as part of the Digital Ventures team. He has continually demonstrated skills in the management of agencies, as well as implementing various marketing initiatives with excellent results. I have no trouble recommending James to anyone.
Katie HammondDigital Content Manager & Agile Coach, The LEGO Group
A brilliant digital marketing freelancer whom I would have no hesitation in recommending. With extensive experience implementing digital marketing strategies for some of the UK’s most exciting startups, and global brands, addressing every stage of the funnel, from acquisition through to customer engagement and retention, James is one of the most approachable, committed and thoughtful professionals that I have had the pleasure of supporting.

Questions

The things founders and leaders usually ask.

What kind of businesses do you work with?

Funded start-ups and scale-ups past product-market fit, mid-market brands, venture studios and their portfolio companies, and corporate innovation teams — mostly B2B, SaaS, DTC and e-commerce.

Are you an agency?

No. We’re a senior, founder-led growth practice — an experienced operator leading the work, not a junior team behind a senior pitch.

Do you run campaigns or just advise?

Both. We set strategy and get hands-on with execution and measurement — that’s the point of the model.

How do engagements work?

Typically a fixed-scope Growth Diagnostic to start, then either retained fractional leadership or a defined project.
