Engagement type · Fractional
E-Commerce growth partner
Two days a week, embedded in your business. Twenty-five years inside ecommerce. One senior operator, no juniors.
Fractional growth · 6 month minimum

Senior marketing leadership.
Without the full-time hire.

For founders running $1M–$10M ARR who need a Head of Growth with skin in the game, not another agency hand-off. I move in for a year, run the function like it's mine, and hand it back to you compounding.

Two to three days a week. Six month minimum. By application only.

The problem · §02

When marketing has no clear owner, it stalls.

Most growing e-commerce brands don't need to hire 'the CMO.' They need someone senior who can sit on top of the marketing function, hold the agency accountable, and own the metrics that actually matter — repeat rate, blended margin, contribution.

Without that, marketing becomes fragmented. Activity goes up, profit doesn't. The brand has 40 things in motion and no one keeping score across them. Customers know. Sales soften.

I sit in that seat for the founders who don't want to fill it full-time yet — or who want a senior peer to read the dashboard before the agency does.

What I own · §03

I run your e-commerce marketing.

Six pillars. Owned end-to-end. No carve-outs, no "that's the agency's problem."

01

E-commerce strategy & ops

End-to-end ownership of the marketing function and the store underneath it. Your team and your agencies report into me; I report into you.

  • Channel strategy & roadmap
  • Promotional & launch calendar
  • Brand → performance alignment
  • Quarterly board summary
02

Paid acquisition

Meta, Google, TikTok — and SEO underneath. The CAC is mine to defend, the budget mine to allocate.

  • Meta · Google · TikTok
  • Creative briefs & testing
  • Agency oversight & QBRs
  • Weekly CAC defense
03

Email, SMS & retention

The quietest lever in your P&L. Klaviyo flows, segmentation, lifecycle, win-back.

  • Klaviyo flows & segmentation
  • Lifecycle, abandoned & win-back
  • SMS where it earns its place
  • LTV & repeat-rate cohort work
04

The store itself

Shopify or Magento. Product listings, pricing, on-site merchandising, mobile & UX — the boring work, done properly.

  • Shopify / Magento / Woo ops
  • Product listings, pricing & images
  • A/B testing & CRO
  • Mobile, UX & site search
05

The numbers · data & reporting

I read your P&L every Monday before you do. GA, dashboards, attribution.

  • GA & dashboard build
  • CAC : LTV by channel
  • Margin & contribution model
  • Board / investor narrative
06

People, partners & process

Your junior in-house marketer gets a senior to learn under. Your vendors get someone who reads the contract.

  • Mentorship for in-house team
  • Agency & vendor management
  • Hiring panels for senior roles
  • Customer service alignment

The path · §06

The path from chaos to compounding.

Less detail than the cadence. More direction than the brochure.

01

Audit & clarity

A single plain-English audit of your marketing function. The two or three things bleeding most are named. The agency reports stop being the source of truth.

02

Working rhythm

Monday mornings have a deliverable. Decisions get made and signed off. Your team knows what's coming next.

03

Channels compounding

Paid, email and SEO are running off one operating system. CAC is defended weekly, retention is moving.

04

Founder time back

Marketing runs without you. You're freed up to spend founder time on product, supply and the rest of the business — and the business is bigger than when I arrived.

For who · §08

Who this is — and isn't —

I'm a poor fit for some founders. Here's the line — both sides. If you see yourself on the right, let's talk.

This is for you if
  • DTC e-commerce. Apparel, home, beauty, food.
  • $1M–$10M ARR, path to $5M+ next year.
  • No Head of Growth, or one who wants a senior peer.
  • A junior in-house marketer already in place.
  • Comfort handing me the keys for 2-3 days a week.
This isn't for you if
  • ·Pre-revenue or pre-product.
  • ·Looking for a freelancer to execute tickets.
  • ·Looking for an agency. I'm one person with a capped book.
  • ·Hourly billing from day one. Minimum is six months.
  • ·Need same-day turnaround Mon–Sun. I don't work weekends.

Questions · §09

The questions founders ask first.

Six years of the same six questions. Six honest answers.

How is this different from hiring an agency?

An agency is a team of mid-level executors managed by a project manager. This is one senior operator, embedded in your business, with skin in the game. The CAC is mine to defend; the dashboard is mine to keep clean.

How is this different from a full-time Head of Growth?

Loaded comp for a senior Head of Growth lands $22–27k a month, plus equity, plus the 18-month industry-average tenure. I cost less than half, I'm available next quarter, and the average client keeps me nine years.

Do you run the ads yourself, or manage my agency?

Either. If you don't have an agency, I run the spend myself. If you have one and they're good, I keep them and hold them accountable. If they're not, we replace them.

Can I bring you on for less than 2-3 days a week?

Scope is customisable, but the minimum useful engagement is two days. Less than that and I become an advisor — and you can hire much cheaper advisors than me.

What if it isn't working at six months?

We part ways. The minimum is six months because the early work compounds slowly; after that it's month-to-month with 30 days' notice.

Where are you based?

Surfcoast, Victoria. Two to three days a week with your team — in person where geography allows, otherwise on calls and inside the dashboards.
