The patchwork stack

Most stores aren't missing retention. They've just never built it properly — and they're leaking revenue they can't see.

Maybe you set up a welcome flow once and never went back to it. Maybe a cheap freelancer built a couple of automations and went quiet. Maybe you've meant to sort your email out for two years and other fires kept winning.

However you got here, the result's the same: a few disconnected pieces doing a fraction of the work, with no real system underneath. That's the patchwork stack — and revenue leaks straight through the gaps.

Here's the part most founders miss. Nearly every store we scan has email that isn't set up right. Not "could be sharper" — actually leaking. Emails landing in spam. Flows half-built or never built. WhatsApp and IG DMs ignored entirely. A list that cost real money to grow, barely earning. And because it's quiet, you can't see the number.

That's the entire reason the Scorecard exists: to put a figure on a problem you almost certainly have, and probably can't see yet.

The Retention OS
One operator. One system. Nothing leaks.
01 · Acquisition tax

You rent every customer

Paid acquisition gets more expensive every quarter. With no system working your existing customers, you pay full price to win back buyers you already owned.

02 · The dead list

The asset just sits there

You've built a list. It cost real money to grow. Right now it's a pile of contacts doing almost nothing — the asset is there, the system that turns it into revenue isn't.

03 · The blind spot

You can't see what it's costing

The leak is silent. No alert fires when an email hits spam, a flow never gets built, or your WhatsApp list sits idle. So the loss runs month after month, invisible, until someone actually measures it.

The benchmark
30%
Your retention should be doing ~30% of your revenue. Most stores sit under 15%.

Whatever we run for you — flows, campaigns, SMS, WhatsApp, ManyChat IG/Facebook automations, reports back through Klaviyo. So that ~30% isn't a vanity stat spread across scattered channels; it's one clean, attributable number you read straight off your own dashboard.

Most stores arrive under 15%. The gap between where you sit and 30% is money you've already earned the right to — sitting in a list that isn't working yet. And 30% isn't the ceiling: one partner we rebuilt runs at 84% of revenue attributed to email. The Scorecard puts your number against the benchmark — in pounds, on your own store, in two minutes.

The Retention OS

Capture → Convert → Retain → Compound. One system, one operator on your account, a bench of specialists behind the build.

Capture feeds conversion. Conversion feeds retention. Retention feeds the compound. Each stage hands off to the next, and the revenue stacks.

  • December email revenue: £5,600

Burned by a previous agency. Then everything changed.

Before — the situation
  • Previous agency: "OK" open rates, no real movement
  • Deliverability quietly broken — emails hitting promotions and spam, not inboxes
  • Months of spend, no shift in the numbers
  • A founder who'd lost trust in agencies
After — Retention OS rebuild
  • Open rates tripled (+200%)
  • A+ deliverability rebuilt across the sending domain
  • Founder access throughout — direct line on WhatsApp and ClickUp, not a help desk

The operator

The person on your first call is the person on every call.

I built GrowYourStore because I watched too many founders get sold by a senior in the pitch, then handed to a rotating junior who'd never run a real D2C program. The work got slower. The voice went generic. The numbers stalled.

So I built the opposite. I'm the operator on your account — every call, every strategy decision, every email signed off before it goes live. Behind me sits a team of specialists running the build work where speed and depth matter: deliverability, segmentation, design, campaigns, ManyChat IG and Facebook automations. You get the senior on every call, and the specialist bench that makes 14 days to live possible.

Eight years running D2C retention programs. Direct access: 24/7, on WhatsApp and ClickUp. Not a help desk. Not a junior. Me.

The Founder Cap: I take a maximum of 15 active brands at a time. I'm on every call, in every strategy doc, signing off the first ten emails, and reachable on WhatsApp and ClickUp around the clock. When I'm full, I'm full: attention is the product.

The offer

You only pay for the growth we create.

It starts with your free analysis. We set your baseline from your last 12 weeks and show you the opportunity on your own numbers. No charge, no obligation.

"We build your entire retention system — Email, SMS, WhatsApp, ManyChat and UGC, live in 14 days. You only pay from the new revenue we create. Your existing revenue is never touched."No setup fee · No retainer · No fixed term contracts

Your revenue is untouched

The share applies only to new growth above your baseline, locked in writing before we start. What you make today stays entirely yours.

The ship guarantee

Your core system is live and sending within 14 days, or your money back. Revenue starts from day 1 of going live.

The revenue guarantee

Most brands reach 30% of revenue from email, SMS and WhatsApp within 12 weeks. If we're off plan, I keep working unbilled until we're back on it. Your existing revenue is never touched.

Two minutes to your number — no call required.
What it costs to wait

Every month you wait, the leak runs.

You keep paying full ad price to win back customers you already earned. Your list keeps cooling. That gap between where you sit and 30% doesn't stay still — it compounds.

That's revenue leaving quietly — month after month, on a list that's already yours.

The Scorecard puts a conservative monthly £ figure on exactly what that's costing you right now.

Questions founders ask before they start

The things founders ask before we start.

We set your baseline from your last 12 weeks before we touch anything, then report revenue above that line, attributed in Klaviyo — every month.

Live in 14 days or your money back. Beyond that, everything we earn comes from new revenue only — no growth means no share. Miss the guaranteed threshold and I keep working, unbilled, until we hit it — the specific number is set with you on the call.

The deal aligns with your P&L, not against it. We get paid from new growth — so we only win when you do.

No. 15-brand cap, Louie on every call. Behind him sits a team of specialists running the build — but the strategy, the calls, the sign-off, and the WhatsApp line are all founder-direct.

The core system — capture, your core automations across Email/SMS/WhatsApp, deliverability — is live and sending inside 14 days. Fit It Out went £5.6k → £24.2k in the first month live. Campaigns and ManyChat IG automations layer in from there.

No — most stores we take on aren't. Half-built flows or nothing at all, the build is the same. The Scorecard shows you where you're starting from.
