How we work with clients
Six commitments that hold on every project, whatever its size.

Senior engineers, start to finish
The people in discovery are the people who ship. You meet your tech lead before you sign.
Commitment 02
You own everything
Code, repositories, accounts and licences are yours from the first commit.

The platform that fits, not the one we sell
Medusa, custom Node.js or Shopify Plus, chosen for your catalogue, systems and budget.
Commitment 04
A gate at every stage
Six delivery stages, each with a deliverable you keep and a sign-off you control.
Commitment 05
Every number says where it's from
Results on this site carry an evidence label: verified, measured, reported or third-party.
Commitment 06
We stay after launch
Monitoring, upgrades and a monthly improvement sprint, with response times in writing.
Trusted by retail, textile and consumer brands
Textile exporters, retail chains and consumer brands trust us with the platforms their revenue runs on.
