Bring in a senior
Our senior growth hacker consultant brings operator-level judgment to your team. Bring in a senior growth hacker who runs your growth as an experiment engine for UK and European product-led SaaS, DTC, and venture-backed companies. One operator, hands-on across acquisition, activation, conversion-rate optimisation, lifecycle and retention, and referral loops, accountable for a growth number from day one. Not an agency retainer and not a junior hire.
Our senior growth hacker consultant brings operator-level judgment to your team
You get one accountable growth hacker, not a team of juniors. They instrument the funnel, find the leaks, and run the experiments themselves. The person you interview is the person doing the work, with the wider Collective bench behind them when a test needs a specialist.
Every growth hacker we place has owned a growth or performance function and been accountable for the metric. They have scaled acquisition, lifted conversion, and rebuilt retention curves at real companies, so they know which experiments are worth running and which are noise.
A good growth hacker is not a bag of tricks. They build a prioritised experiment backlog, run it at tempo, measure honestly, and optimise conversion stage by stage. Every test ladders back to a metric, so you know which wins to scale and which to kill.
Founders and growth leads bring in a growth hacker at predictable moments: an acquisition channel that has stopped scaling, an activation or onboarding step where users drop off, a retention curve that flattens too early, or a product with strong usage but no repeatable growth motion. Each needs a different experiment, and most of all a person who has actually built the growth engine before and can start running it now.
The wrong hire chases tactics from a blog post. The right growth hacker starts with your funnel: they instrument acquisition, activation, conversion, and retention, find where the biggest leaks are, and build a prioritised experiment backlog against them. They are equal parts marketer and analyst, comfortable in the data and willing to ship a landing-page test on the same day they brief a paid campaign.
Our growth hackers do not hand you a deck and leave. They embed, run the experiment backlog, wire up the analytics and optimisation loop, build the lifecycle and referral programmes, and hold the weekly testing cadence that keeps velocity high. You get a senior operator shipping experiments, available interim or fractional, for as long as the engine needs building.
A two-week diagnostic across acquisition, activation, conversion, and retention. Where the funnel leaks, which experiments to run first, and where the spend is wasted. Senior operators on it from day one.

Common questions from teams evaluating a growth hacker.
Our growth hacker consultant advises: A growth hacker runs your growth as an experiment engine. They instrument acquisition, activation, conversion, and retention; find where the funnel leaks; build a prioritised backlog of experiments; run them at tempo; and scale the winners. It is growth by structured testing, owned by one accountable operator rather than a fixed playbook.
Our growth hacker consultant advises: An agency usually runs paid acquisition with a junior account team. A growth hacker is one senior operator who works the whole funnel, including activation, conversion, retention, and referral, and builds the analytics and cadence that make experimentation repeatable. If you need an accountable owner of growth rather than channel execution, hire the operator.
Our growth hacker consultant advises: Yes. Most engagements start interim or fractional: a senior growth hacker embedded a few days a week to build and run the experiment engine while you decide whether to hire permanently. You get senior hands on the funnel without committing to a full-time hire on day one.
A focused funnel diagnostic runs about two weeks, and the first experiments typically launch inside the first few weeks, with a weekly test cadence after that. Growth hacking is a high-tempo discipline; a good operator gets tests live quickly.
Yes. A large part of the job is making your existing stack trustworthy: clean event tracking, sound funnel reporting, and optimisation tooling they can rely on. They instrument what you have before recommending anything new, because experiments are only as good as the data behind them.
