Every piece of software starts as a sketch.

Who we are

Yengech is a software company founded in Istanbul in 2026. From web and mobile apps to enterprise systems, we build every kind of software in Karqen, the software factory we built ourselves. Our name comes from yengeç, Turkish for crab.

What we believe

AI is changing how software gets made. Almost anyone can produce software today, yet much of what gets produced quickly ships with security holes, weak performance and code no one can maintain. We combine the speed of AI with engineering discipline: software that actually serves your business, secure, fast and built to last.

Our principles

• Understand firstWe start by understanding what you need and why, not by writing code.
• Quality is not negotiableSecurity, performance and maintainability are part of every job, never added later.
• OpennessWe tell you plainly what we are doing, why, and where things stand.
• We keep our wordWe do not promise what we cannot deliver.
• We think long termDelivery is not the end; we stay with your software for as long as it lives.

From idea to working software

1. IntroductionWe listen to your needs, goals and priorities.
2. DiscoveryWe pin down the scope together: screens, data, integrations, risks.
3. ProposalWe set out in writing what will be built, how it will be delivered and what it costs.
4. ProductionYour software is built and tested on Karqen, and you follow its progress step by step.
5. DeliveryWe take the working application live.
6. Care and growthAfter delivery, we keep improving your software.

Who we work with
