Why ntagks
Engineers who think like owners.
We’ve been in your shoes.
We have built and sold our own apps, so we focus on what grows your business, not just on the code.
One partner, end to end.
Design, development, launch and support from one team. No hand-offs, no finger-pointing.
Clear price. Clear timeline.
A fixed proposal before we start, and honest updates every week.
Worldwide from day one.
We work with businesses and startups around the world, and the apps we build are already used in more than 150 countries.
Every project is different. After a short, free intro call, we send a clear proposal with scope, timeline and a fixed price. For ongoing work, we offer a simple monthly plan.
A first version is often ready within a few months. We plan in small steps, so you can launch early and improve as you go.
Not at all. You bring the idea and the business know-how; we take care of the technology and explain every decision in plain language.
Yes. We start with a review, fix what is urgent, and then improve it step by step, without disrupting your customers.
We stay with you: monitoring, updates and new features on a monthly plan. Or we hand everything over to your own team, fully documented.
No. We work with clients all over the world, and everything happens online: calls, design reviews and weekly updates, at times that suit you.
