Is this you?

The signals that usually bring founders here.

  • You know this quarter matters but you have a list of ideas rather than a structured experiment plan
  • You're raising in the next 6 months and need clean growth signal for investors before then
  • You've launched and you're not sure which channels are actually working vs which are just active
  • You're about to make a CMO or growth hire and want to prove the operating system first
  • The team has execution capacity but no senior structure around what to test, why, and in what order

How we work

We design, your team ships, we decide together what to scale.

What WSS brings

  • Quarterly experiment roadmap, ICE-scored
  • Weekly sprint meeting facilitation and decision capture
  • Positioning, landing-page, and campaign iteration support
  • Pipeline + conversion reporting setup
  • End-of-sprint transfer checklist for the team

What you bring

  • An execution owner inside the team
  • Existing creative / dev / content capacity (in-house or agency)
  • Founder availability for 30 minutes per week
  • Tracking access and budget for any tests requiring spend

Outcomes

  • ICP and positioning decisions translated into pages, campaigns, and sales narrative
  • Experiment roadmap with hypotheses, owners, and decision rules
  • Landing page, content, paid, outbound, or CRO tests selected by stage and budget
  • Weekly reporting rhythm that links activity to pipeline and learning

Process

  1. Diagnose current funnel: export GA4 events, CRM stage conversion rates, and listen to 5 recent sales calls to hear the real objection
  2. Select 3–5 experiments using ICE: (1) impact on pipeline velocity, (2) confidence from past data, (3) ease of execution with current team
  3. Build experiment assets: (1) 2 landing page variants with different value props, (2) 3 ad creative sets per channel, (3) email sequence with behavioural triggers
  4. Friday weekly review: calculate CPL trend, MQL conversion rate, pipeline velocity; scale experiments >2x ROI, kill <1x ROI, document learnings in a working backlog your team owns

Example deliverables

  • Quarterly experiment roadmap (6–8 prioritised tests)
  • Weekly sprint meeting and decision notes
  • Positioning, landing-page, and campaign iterations (briefs + reviews)
  • Pipeline and conversion reporting dashboard
  • End-of-sprint transfer checklist for the team

Representative output

Experiment cards, weekly decision notes, and an end-of-sprint transfer checklist — tuned to how your team ships. Example formats are available on the diagnostic call.

Illustrative layout — final deliverables are client-specific.

Sample week

  1. Monday: experiment planning and prioritisation
  2. Tuesday-Wednesday: asset review and iteration
  3. Thursday: launch or iteration go-live
  4. Friday: performance readout and decision capture
  5. Ongoing: transfer notes after each test

What happens after the engagement

Most teams continue with Fractional CMO support to keep the rhythm. About 1 in 3 take the transfer pack and run the next quarter internally.

Common mistakes

What founders usually try first — and why it doesn't move the needle.

Running too many experiments without success criteria

Without decision rules upfront, you end up with a lot of data and no clear signal on what to scale — everything feels inconclusive.

Changing creative before testing the offer

Better images won't fix a weak value proposition. The test order matters as much as the test itself, and most teams get it backwards.

Stopping tests before they reach significance

Most experiments get paused after one bad week — before enough data exists to make a clean scale or stop call. The rhythm breaks and the learning is lost.

In their words

What founders say after the engagement.

"We ran six experiments in 12 weeks, scaled two, killed three, and fixed one. More signal in one quarter than the previous year of activity."

— Founder, B2B SaaS, Seed

"The sprint gave us the growth story for our Series A deck. Clean data on what worked, what we learned, and what we'd do next with more capital."

— CEO, AI platform, pre-Series A

FAQ

What founders ask before they book.

Who is this for?

Founder-led teams that need focused tests this quarter, not another broad strategy deck. Often used before fundraising (clean signal for investors), after a launch (find what's actually working), or before a CMO hire (prove the system before committing).

What do we get?

Six to eight targeted experiments shipped, a weekly operating rhythm the team owns, a reporting view of what worked, and a transfer checklist so the system continues after the sprint.

How long does it take?

12 weeks. Week 1 is planning, weeks 2–11 are execution and iteration, week 12 is readout and transfer.

What does it cost?

From £15k for the standard 90-day sprint. Test budgets (paid media, tooling, creative) are separate and you control them.

What do you need from us?

An execution owner, existing creative / dev / content capacity (in-house or agency), 30 minutes of founder time per week, and tracking access. We design and direct; your team ships.

What happens after the engagement?

Most teams either move into Fractional CMO support to keep the rhythm going, or take the transfer pack and run the next quarter internally. A clean readout document is yours either way.

Decision point

Bring the current bottleneck.

20 minutes. We'll decide whether this is the right shape of help, what the first 30 days should focus on, and what should not be touched yet.
