About
GrowthX is the growth consultancy that turns ambition into predictable revenue.
One partner from first audit to boardroom: strategy, execution, and experimentation working as one.
Alex Carter
Founder & Growth Lead — GrowthX
GrowthX began with Alex Carter’s obsession with one question: why do most growth programs flatline? Since 2019 he has led the consultancy end to end — strategy, execution, and experimentation for teams that want numbers they can trust.
The approach is simple: connect your stack, ship measurable experiments, and let disciplined execution compound what works — with a founder who still joins every client’s weekly review.

Mission
We believe growth is a system, not a gamble — built on data, discipline, and relentless iteration.
GrowthX exists because most teams are drowning in dashboards and starving for direction. We replace guesswork with a system: every metric connected, every experiment measured, every win compounded.
That belief shapes our work — analytics your whole team trusts, execution that follows through, and experiments that turn insight into revenue.

Philosophy
Four principles behind every experiment we ship.
01
Data over opinions
Every decision starts with a metric. If we can’t measure it, we don’t ship it — evidence beats opinion, every time.
02
Compounding beats spikes
We design for systems that get stronger every week: retention first, then activation, then acquisition — in that order.
03
Speed with discipline
Forty experiments a quarter, each with a hypothesis and kill criteria. Fast never means careless.
04
Numbers people can trust
One source of truth for the whole team. Growth is a team sport played on shared, legible data.
