Your client’s experimentation programme doesn’t stop because your team is at capacity.
I plug into agency teams to deliver experimentation work under your processes, at your standard, without adding to your team’s load.
Three ways we can work together
Deliver under your process
I pick up experimentation briefs and deliver work under your agency’s methodology. Test design, implementation, analysis and documentation — to your standard and on your timeline. Your client sees seamless delivery. You see capacity restored.
Advise your team
Your team has the capacity but needs a more senior perspective. I work alongside your experimenters to review test designs, sense-check hypotheses and provide statistical rigour where it’s needed. Knowledge transfer included.
Build your CRO Practice
You want to offer experimentation to clients but don’t have the internal capability yet. I work with your team to establish the methodology, build the processes and run the first programmes alongside them — transferring the knowledge so your team can own it independently.
I offer years of proven experience driving in house and agency experimentation programmes.

What you’re getting
Someone who can pick up an experimentation brief and deliver without needing to be managed. I work across the full experimentation stack — Optimizely, VWO, SiteSpect, AB Tasty and AB Smartly — and I’m comfortable with both JS DOM manipulation for tool-based implementation and briefing developers for more complex builds.
I design statistically rigorous tests, analyse results properly and document everything to your standard. Your client sees seamless delivery. Your team doesn’t pick up extra work.
You won’t need to explain what a confidence interval is.
Simple to start
Get in touch
Tell me what you need and when. I’ll tell you straight whether I can help and turn around a plain-language scope within a few days.
We agree the arrangement
Day rate or fixed scope depending on the work. I invoice you directly. 14 day payment terms.
I plug in
I work to your processes, your tools and your timeline. You stay the client relationship. I stay the delivery resource.
Work delivered
Tests designed, implemented and analysed to your experimentation standard. Documentation handed over. Ready for the next brief when you need it.
Who this works for
You’re a digital, CRO or growth agency with an experimentation client you can’t service right now. Your team is stretched, a specialist is unavailable or the programme is more complex than your current capacity can handle. You need someone who can step in without a lengthy briefing process and deliver work your client won’t be able to distinguish from your own team’s output.
Or you’re building out a CRO practice and need someone to stand it up properly — establishing the methodology, running the first programmes and training your team to own it independently.
Either way you need someone who understands agency dynamics, works to your processes and doesn’t create more coordination overhead than the work saves.
Common questions
Everything shared with me is treated as confidential. I work under your agency’s NDA or standard confidentiality terms and never share client information with third parties. Your client relationship stays yours.
Yes. I work under your agency’s banner and never contact your client directly unless you specifically ask me to. Your client sees your agency’s work. How you represent my involvement is entirely your call.
I’ll tell you upfront if I’m already working with a direct competitor in the same space. If there’s a genuine conflict I’ll say so before we agree anything. If there isn’t, I’ll confirm that too.
Day rate or fixed project price depending on the work. I invoice you directly. Payment terms are 14 days.
Usually within one week of an agreed engagement. If you have something urgent, get in touch and I’ll tell you what’s possible.
Yes. I can talk through past engagements in detail — the problem, the approach and the results — without naming the client. You’ll get a clear picture of how I work and what I deliver without any confidentiality being compromised.
I may reference engagements I’ve delivered as case studies — describing the problem, approach and results without naming the end client or the agency unless explicitly agreed. If you have concerns about this, we can agree specific terms as part of the engagement.
I use AI to support research synthesis and generate analytics artefacts. Client data is never shared in a way that trains models. If your client has specific AI policies I can work within them.
About
Meet Storm Jarvie
I genuinely believe the best decisions start with admitting what you don’t know yet. Not as a methodology. Just as a way of working. It keeps the work honest and it tends to produce better outcomes than starting with the answer and working backwards. That’s the thread running through everything I do in Experimentation.
