Testimonials

What clients say when the project is actually delivered.

Six clients. Different industries, different project types, different starting points. What they have in common: they got what was agreed, on time, with documentation they could actually use.

“After two agencies who disappeared after launch and left us with undocumented spaghetti code, working with OYK was a completely different experience. Every decision was explained, everything was documented, and the handover was the most thorough we have ever received.”

Marcus H. · CTO · Amsterdam, Netherlands

“Our platform was falling over at 50 concurrent users. OYK rebuilt the backend architecture and now we handle ten times that during peak periods without it being a concern. The performance improvement was immediate and measurable.”

Sarah L. · Founder · London, UK

“We had a hard launch deadline tied to a product event we could not move. OYK delivered with a day to spare. That kind of reliability is genuinely rare in web development and it is what we will always come back for.”

Daniel K. · Product Manager · Berlin, Germany

“The discovery process at the beginning felt slow at the time. Looking back, it was the reason the build went smoothly. We had already made every important decision before a line of code was written. No pivots, no rewrites, no emergency calls.”

Priya M. · Head of Product · Stockholm, Sweden

“We asked for a Shopify build with a custom wholesale module. Three other agencies told us it could not be done cleanly on Shopify. OYK built it, documented it, and it has been running without issues for fourteen months.”

Tom B. · E-commerce Director · Dublin, Ireland

“Fixed-price development from a team that actually honours the fixed price. That sounds like the minimum bar, but it is apparently rare enough to be worth mentioning. No scope creep, no surprise invoices, no ‘that was out of scope’ at the end.”

Elena V. · Operations Manager · Vienna, Austria
Patterns

Three things clients consistently value.

01

The handover is actually usable

Documentation that gets written and maintained during the project, not thrown together at the end. The next developer can get a local environment running without a call to us.

02

The price stays fixed

Scope changes get flagged immediately and priced separately. There are no surprises in the final invoice because we are honest about scope from the beginning.

03

The deadline is real

We do not agree to deadlines we cannot hit. If something threatens the timeline during the project, we flag it immediately — not on the day it was supposed to be delivered.

Your project

You could be next. Tell us what you need built.

A short paragraph about the project is enough to start the conversation. We will come back with honest feedback on feasibility, timeline, and price — not a proposal designed to tell you what you want to hear.

Common reasons clients come to us

“The last agency disappeared after launch” “We got a surprise invoice at the end” “Nobody documented what they built” “The platform cannot handle our growth”
