About Us

Key Yazılım Çözümleri A.Ş. was founded in 2004 and operates as an R&D center within Bilkent Cyberpark. The platforms we develop in real estate valuation, mortgages, and asset management are actively used by Turkey's leading banks and financial institutions. With a team of over 40 experts and continuously growing R&D investments, we produce technologies that shape the industry.

" Listen Well, Understand Rightly, Strive for Excellence in Implementation "

At Key Yazılım, we begin our work not with solutions, but with understanding. Because we know that each institution's needs, each process's dynamics, and the real reasons behind each decision are different. This is why our first step is not to talk, but to listen well.

Listening means more than just hearing what is said. It requires understanding the process background, the institution's habits, the challenges encountered, and often unspoken expectations. When we act with this understanding, we identify not just the right solution, but the right problem.

Understanding correctly, for us, is not just a stage but a responsibility. Because every system we develop becomes part of the daily operations of banks, valuation firms, and our partners. This is why we act with the awareness that every step we take must have a real-world impact.

Yet we prefer to say "we continue to strive for excellence" rather than "we did our best." Because technology, needs, and processes constantly change. What is right today may be open to improvement tomorrow. This is why we see perfection not as a destination, but as a path we continuously walk.

This approach keeps us attentive, open to learning, and always ready for improvement. And that is exactly why our goal remains the same in everything we do: Listen well, understand rightly, and always strive for excellence in implementation.

Listen Well

Every project begins with discovery meetings. We meet with stakeholders from end users to executives; we observe workflows on site and map out needs together.

Understand Rightly

Our 20+ years of industry experience, regulatory knowledge, and field insights enable us to interpret what we hear correctly. Our solutions are designed to work in real operations, not just on paper.

Strive for Excellence

Through regular release cycles, user feedback, and our continuous improvement culture, we advance our products every day. We see it not as a perfect destination, but as the path we walk.

Intelligent Support Platform
for Valuation Processes

INVEXUS.AI is not a standard tool built on top of a ready-made artificial intelligence service; it is an artificial intelligence model trained specifically for the sector, developed with consideration for the unique needs of Turkey's real estate valuation industry. The model, trained with a dataset based on SPK Announcement (III-62.3), TUDES/UDS, Land and Property Laws and all relevant regulations, provides instant regulatory guidance, process support and ease of compliance with bank-specific criteria to valuation experts through thousands of validated question-answer pairs. The training process was conducted in local data centers equipped with NVIDIA GPU hardware, with no dependency on third-party cloud services at any stage.
