The senior growth partner behind Phenom Digital.

A founder-led growth practice giving ambitious businesses senior growth leadership — and the operating system beneath it — without the cost and lead time of a permanent executive hire.

Who you’ll work with

The founder you actually work with.

James Treacher, founder of Phenom Digital

Phenom Digital is led by its founder, James Treacher. When you work with Phenom, James is the senior operator in the room — not a name on a pitch deck who hands you to a junior team.

His career has been spent building and leading growth in demanding places: performance and growth marketing inside a global enterprise, growth architecture across a venture portfolio, and digital leadership on the agency side. That mix is deliberate — it is what lets the practice bring enterprise rigour and venture pace to the same problem.

He started Phenom to give ambitious founders and leadership teams direct access to that seniority, without the cost, lead time or politics of a permanent executive hire. Every engagement runs through him.

A rare combination

Enterprise rigour, venture pace.

Most growth specialists have worked in one world. We’ve worked across three — inside a global FMCG digital venture leading growth across 20+ markets under real corporate governance; inside a leading venture builder, standing a B2B venture’s demand engine up from zero; and inside a global communications group, leading B2B demand for enterprise-technology clients.

Client names withheld under confidentiality; available to discuss under NDA.

What we believe

Four convictions about growth.

  • Growth is a system, not a series of campaigns. Build the operating system and results compound.
  • If you can’t see CAC, payback and pipeline in one place, you’re guessing. Measurement comes first.
  • Brand and performance aren’t opposites. Equity and rigour drive revenue together.
  • Seniority means judgement and accountability — knowing what not to do, and owning the number.
