FAQ

Frequently asked questions.

What does Sone Yazılım do?

We're a software company in Istanbul. We build custom software, AI systems, cloud infrastructure, and mobile apps for businesses. We've shipped over 40 projects and maintain a 99.9% uptime SLA.

How much does custom software cost in Turkey?

Depends on what you're building. Istanbul rates are typically 40-60% lower than Western Europe or the US for the same quality of work. We can give you a realistic estimate after a quick call.

Do you work with international clients?

Yes. We work with companies in Turkey, Europe, and the US. Our founding team started in New York before moving to Istanbul. We work in English and Turkish.

What tech stack do you use?

We're not married to any framework. In the AI era, which runtime processes your code matters less and less. What matters is which path is better for your business. We stay current with the latest tools and pick whatever gets the job done for you.
