Private label / Development and quality control
The work we do ourselves.
GEKKO Agency is not a factory and does not pretend to be one. What we do ourselves in Rotterdam decides whether a collection is right: development, tech pack, pattern, sampling and fitting, fabric and colour approvals, the final inspection and the packaging. Production runs at fixed partners we have worked with for years, from 250 pieces per style per colour, checked against the sample you approved.

What do we do ourselves, in Rotterdam?
- 01DevelopmentFrom concept or references to a tech pack: construction, measurements, materials, trims, labels, packaging.
- 02Pattern and gradingPattern made and graded for your size set, in-house.
- 03Sampling and fittingFitting sample and pre-production sample, fitted and adjusted with you. Two rounds are usual.
- 04Fabric and colourSelection from our library or development for you; lab dips and fabric approvals before the order.
- 05Quality controlFull quality checks at the production partner and again in Rotterdam before anything ships.
- 06Labelling and packagingWoven, printed and custom labels, tags, polybags and cartons, as specified.
How do the production partners fit in?
Fixed production partners cut, sew and finish to our tech pack and the approved pre-production sample. We plan the production with them, order fabrics and colours, follow progress and check the result on their side and again in Rotterdam. Certifications such as GOTS and OEKO-TEX, and SMETA audits, are available per production and issued to the production house. We show you the scope.
All nine steps, from tech pack to deliveryWhat else do brands ask?
What exactly do you do yourselves, and what do the partners do?
At GEKKO Agency, development, tech pack, pattern, sampling, fitting, fabric and colour approvals, the final inspection and the packaging specification are ours, in Rotterdam. Cutting, sewing and finishing happen at fixed production partners we have worked with for years, with full quality checks on their side as well.
Where are the production partners?
We do not publish locations or partner names. What we do publish is how we control the result: the approved pre-production sample is the standard, and every production is checked against it at the partner and again in Rotterdam.
How is quality checked?
Full quality checks at the production partner and again in Rotterdam before anything ships. The approved pre-production sample is the standard every piece is checked against.
Which certifications apply?
Certifications such as GOTS and OEKO-TEX, and SMETA audits, are available per production and issued to the production house. We tell you which apply to your production and show the scope. We do not claim certifications GEKKO does not hold.
Can we visit?
The studio and the warehouse at Van Graftstraat 10 in Rotterdam, by appointment: yes. That is where development, sampling and the final inspection happen. A visit to a production partner is possible by appointment too.
