We get to know your setup
We start with a kickoff call, get access to your Shopify store and run a short analysis.
Within a few days we know where we can make the biggest difference — not just once, but continuously.
The longer we work together, the better we know your store — and the more of your setup questions we can answer over time.
We are not here for the short term; we become your go-to tech partner.
Usually not. Our work has the biggest impact in a long-term partnership. We only take on projects in clearly defined exceptions.
Freelancers often work alone and without the full picture.
With us you get a dedicated development team that knows your Shopify store, takes ownership and stays at your side for the long run.
We stay in your setup for months and years — no constant onboarding, no lost knowledge.
No constant search for new people, no dependency on a single person, consistently high quality.
We prioritize together
Every month we discuss which topics have the biggest impact — e.g. checkout optimization, integrations or new markets. Because we know your store, we can also proactively suggest things that earn you revenue or save you time.
You get more than implementation: real technical input that fits your business.
We deliver in sprints
We work in short, clear development cycles.
You see progress every week — instead of waiting months for results.
Because the collaboration is continuous, we build on what we have already shipped and improve it step by step.
Predictable results, faster launches and a store that keeps getting better.
We stay on it
We monitor that everything runs stably, react quickly to new requirements and keep you in the loop.
Once a week we go through current topics with you or your marketing team.
Problems get solved before they cost revenue. You do not have to worry about anything — we are your extended arm for everything technical.
We always start with three months.
In that time we ship the most important topics, get to know your Shopify store inside out and make sure you see first tangible results.
At the end of the three months we sit down and decide together whether it is a fit for both sides to continue.
You get fast impact, a clear time frame — and no long-term commitment if it does not fit.
