Enterprise experience
Bank virtual POS integrations and payment switches, multi-tenant SaaS platforms, back ends for AI apps.
Transparent quote, measurable delivery

Process
From idea to launch in five steps
- 01
Discovery
We listen to the goal, the users and the constraints. A free 30-minute call.
- 02
Quote and plan
Scope, timeline, milestones and price — in writing.
- 03
Design
Screen flows and architecture. What gets built is clear before any code is written.
- 04
Development
Two-week cycles, each ending with a working version you can try.
- 05
Launch and care
Stores, servers, monitoring and updates. Software lives on after launch.
Frequently asked questions
How do I get a software development quote?
Fill in the form on the contact page or message us on WhatsApp. After a short discovery call we send scope, timeline and price in writing. The quote is free and non-binding.
How long does a software project take?
It depends on scope. A lean MVP can launch in a few weeks; a comprehensive enterprise system in a few months. Because we work in two-week cycles, you see a working version early.
Who owns the source code?
Unless the contract says otherwise, the source code, documentation and deployment accounts are handed over to you at the end of the project. You are never locked in.
Does AI integration put our data at risk?
Not when it is set up properly. We mask personal data, run models on your own infrastructure when needed, and apply GDPR-compliant logging and retention rules.
Do you work with companies outside Turkey?
Yes. We communicate in English and Turkish and launch products in 12 languages. Meetings are online and time zones are planned in from day one.
Can you take over and extend our existing software?
Yes. We first review the code and infrastructure and write a status report, then propose a prioritised plan for security, performance and new features.
