FREELANCE GROWTH MARKETER

Growth experiments that move the business forward

I design, run, and document high-impact growth experiments for scaling startups to unlock growth opportunities across the full-funnel.

In-house marketers intend to run growth experiments, but often get sidetracked by the day to day.

For many reasons: 


• Experiments get deprioritised for urgent requests and fire-fighting

• Ideas are captured, but rarely scoped, prioritised, or shipped

• Tests are rushed or half-run with unclear success criteria

• Learnings live in people’s heads, Slack threads, or not at all

• The same ideas get revisited because nothing is properly documented

• Growth becomes a background task instead of a deliberate system

What I do

I run a structured, sprint-based growth experimentation process for B2B scaleups that compounds learning and results over time.

01

Growth diagnosis & opportunity mapping

We start by understanding where experimentation will matter most.


  • Review funnel performance across acquisition, activation, revenue, and retention
  • Identify biggest constraints and bottlenecks
  • Map opportunities across the full journey:
    • Buyers who don’t know you yet
    • Active prospects and deals
    • New and existing customers
  • Align on what “success” actually means (not vanity metrics)


This ensures we’re testing important things, not just easy ones.

02

Build a prioritised experiment backlog

Next, we create a clear, ranked backlog of experiments.
‍

This becomes a living backlog you can keep using long after I’m gone.

  • Hypothesis-driven experiment ideas
  • Clear definition of:
    • What we’re testing
    • Why it should work
    • What success looks like
  • Prioritised by:
    • Expected impact
    • Speed to run
    • Confidence in learnings


03

Run focused growth sprints

I work in short, defined sprints — typically one experiment at a time.


  • Agree the single experiment to run next
  • Define metrics, timelines, and guardrails
  • Ship quickly without over-engineering
  • Avoid running multiple tests that muddy learnings


The goal is fast, validated learnings, with high-impact outcomes.

04

Measure results and extract learnings

Every experiment ends with a clear outcome.
Failures are treated as progress.

  • Did it work, fail, or partially work?
  • What changed, and why?
  • What would we do differently next time?
  • What should this unlock next?

05

Document experiments and decisions

All experiments are documented in a shared system.


  • Hypothesis
  • Method
  • Results
  • Learnings
  • Follow-up actions


This builds an internal growth knowledge base so learning compounds instead of resetting when people leave.

06

Repeat, refine, and scale what works

Over time:


  • Winning experiments get doubled down on
  • Failed ideas are retired permanently
  • Patterns emerge across channels and funnel stages
  • Growth becomes systematic, not reactive

You’re left with a repeatable experimentation engine, not dependency on one person.

Who This Is For

This works best if you:


  • Are a B2B scale-up doing over £5m in revenue
  • Have some data, traffic, or customers to learn from
  • Want clarity on what to test next and why
  • Are tired of unstructured growth efforts
  • Want learnings your whole team can reuse
  • Feel like you’ve hit a ceiling

Why people work with me

  • Hands-on experience running growth experiments across multiple businesses
  • Strong judgement on what’s worth testing, and what isn’t
  • Comfortable working across the full funnel, not just on the acquisition side
  • Bias toward high-impact, fast-learning experiments
  • Clear documentation so learning compounds over time
  • You don’t just get experiments run. You get a growth system your business can keep using.
WHY NOW

Break through the ceiling with growth experiments

Economic headwinds and increased market competition mean that marketing teams today are expected to do more with less. Growth experiments via a freelancer can help you unlock more opportunities for growth, without sidetracking your team.

FAQs

What are growth experiments in B2B?

Growth experiments in B2B are small, structured tests designed to answer specific growth questions quickly, without committing large budgets or long timelines.

Instead of guessing which channel, message, or tactic will work, growth experiments are used to:

  • Validate assumptions
  • Reduce risk
  • Learn what actually moves pipeline and revenue

In a B2B context, experiments can sit anywhere in the funnel, including:

  • How buyers discover your product
  • What messaging resonates with real decision-makers
  • Which channels generate buying-intent leads
  • How deals move through the pipeline
  • What improves conversion or deal quality

Each experiment starts with a clear hypothesis, a defined success metric, and a short timeframe. If it works, it’s scaled. If it doesn’t, the learning is captured and the business moves on — without sunk-cost attachment.

For B2B companies, growth experiments are especially valuable because:

  • Sales cycles are long and expensive
  • Channels behave differently by category
  • Buyer behaviour is hard to predict
  • Scaling the wrong thing is costly

Growth experiments create a repeatable way to learn and make decisions, rather than relying on opinions, playbooks, or copying what worked for someone else.

In short, growth experiments help B2B companies move forward with evidence instead of assumptions.

Do you run experiments across the full funnel?

Yes. Growth experiments can be run across the entire B2B funnel, not just at the top.

That includes experiments focused on:

  • Demand creation – how buyers discover you and form initial awareness
  • Demand capture – which channels and messages attract buying-intent leads
  • Conversion – what improves sign-ups, demos, or qualification
  • Pipeline – what increases opportunity creation, velocity, or win rates
  • Revenue – what influences deal quality, deal size, or close rates

The focus isn’t on running lots of disconnected tests. It’s about identifying where the biggest constraint is right now and experimenting there first.

For some teams, that’s getting more of the right leads in. For others, it’s improving conversion, shortening sales cycles, or increasing win rates.

Experiments are prioritised based on:

  • Business goals and current bottlenecks
  • Where small changes could create outsized impact
  • What can be tested quickly with minimal risk

Running experiments across the full funnel ensures learning translates into real commercial progress, not just surface-level optimisation.

How many experiments do you run at a time?

Usually one core experiment at a time.

That’s deliberate.

In B2B, running too many experiments in parallel often:

  • Dilutes focus
  • Confuses results
  • Makes it hard to know what actually worked
  • Spreads limited resources too thin

The goal isn’t volume of experiments — it’s quality of learning.

A single experiment is typically supported by:

  • Clear hypothesis and success criteria
  • One primary variable being tested
  • Enough time and traffic to generate a meaningful signal

In some cases, small supporting tests (for example creative variations or messaging angles) may run alongside a main experiment, but there’s always one clear learning objective at a time.

This approach ensures:

  • Results are interpretable
  • Decisions are defensible
  • Learnings can be scaled or discarded quickly

For most B2B teams, progress comes faster by running fewer, better experiments — not by trying to test everything at once.

How do you decide which experiments to run first?

Experiments are prioritised based on impact, speed, and effort — with the goal of learning as much as possible, as quickly as possible, with the least risk.

The first experiments are usually the ones that:

  • Have the highest potential impact on the business
  • Can be validated quickly with real data
  • Require the least time, budget, or engineering effort

In practice, this means starting with experiments that can:

  • Unblock revenue or pipeline
  • Improve conversion or lead quality
  • Validate or invalidate key assumptions
  • Create momentum through quick wins

Rather than running “interesting” tests, the focus is on experiments that answer the most important questions the business is facing right now.

As learnings compound, experiments become more ambitious — but only once the foundations are clear.

The aim is not to run as many experiments as possible, but to run the right experiments at the right time, so effort turns into insight and progress, not noise.

Is there a minimum commitment?

Yes — there’s a three-month minimum commitment for growth experimentation work.

That timeframe is important because it allows enough time to:

  • Identify the right problems to focus on
  • Design and run meaningful experiments
  • Gather reliable signals (not just early noise)
  • Turn learnings into clear decisions

Growth experimentation isn’t about running one-off tests. It’s about building momentum and learning over multiple cycles.

After the initial three months, the engagement can continue on a flexible, month-to-month basis.

The aim isn’t to lock you in — it’s to give experimentation a fair chance to create real value.
