Interim CMO for E-commerce & D2C Brands

Rebuilding paid acquisition, retention, and MarTech for €5M–€100M D2C brands. Operational from day one. Engagements from €5,000 to €25,000 per month.

By Joris van Huët · Updated 2026-06-15

The pattern

"Meta and Google CACs in D2C rose 222% between 2014 and 2022, while iOS 14.5 removed 60% of the optimization signal — the brands still using 2021's playbook are funding that gap with their margin." — ProfitWell / Paddle, 2023

Pattern 1

Paid CAC has risen 222% since 2014 and your last creative refresh did not move it.

Pattern 2

Klaviyo, Bloomreach, and three other vendors overlap; nobody owns the stack.

Pattern 3

Post-iOS attribution turned your dashboards into theatre — you need causal proof.

Pattern 4

Retention rate stalled; first-purchase economics no longer pencil out.

Frequently asked

How quickly can you start with my D2C brand?

Inside a week for most engagements. The first 14 days are a written stack audit, a channel-mix reset, and an organisational diagnostic. By day 30 you have a board-grade dashboard prototype.

Do you work with Shopify Plus or only enterprise commerce platforms?

Both. Most engagements are Shopify Plus brands in the €5M–€100M range; some are commercetools or Salesforce Commerce Cloud at the upper end.

How do you handle paid media if attribution is broken?

Geographic holdouts, MMM-lite, and incrementality testing. We rebuild the measurement before we rebuild the spend. A €10,000/month engagement typically pays back within 4–6 weeks on reallocated paid budget alone.

Will you replace my existing agency?

Sometimes. The decision is data-driven: if the agency is delivering and the issue is in-house, we fix in-house. If the agency cannot defend its work in week 2, we run a structured agency review.
