About

A small studio that would rather be right than busy.

Shlafzn is an ecommerce performance studio in London. One team across paid media, creative, CRO, Shopify and server-side tracking, so no department can blame the other.

Principles

Five rules we do not bend.

  1. 01

    Measurement before media

    Nothing scales until the server can explain the order. A budget increase on a broken readout is a bigger broken readout.

  2. 02

    Orders over dashboards

    The ad platforms get a voice. The Shopify order export, refunds included, gets the final word.

  3. 03

    Consent is a feature

    A refused marketing consent is forwarded as a refusal, not routed around. Trust is part of conversion.

  4. 04

    Creative with a hypothesis

    Every concept says what it is trying to prove. A winner teaches something; a lucky frame teaches nothing.

  5. 05

    The number we cannot defend

    If a figure does not survive the order export, we do not publish it. That includes our own case studies.

Plain speaking

What we are, and what we are not.

We are

  • A London studio incorporated in 2026.
  • Hands-on implementers of Stape, Addingwell, Shopify customer events and the ad platforms’ server APIs.
  • Readers of the order export first, and of the ad manager second.

We are not

  • Stape, Addingwell or Shopify, and we claim no partner status unless a statement of work says so.
  • A fifty-person agency with a floor of account managers.
  • Willing to publish a return figure the orders do not support.

09 — Start a project

Let’s make it perform.

Bring the store, the ad accounts and the figure you do not trust. We will tell you if the first job is measurement, media or the page.
