Today marks a new chapter.
With the official launch of spotlight core²code, a place emerges where IT strategy becomes reality – and innovation meets structure.
We live in a time of rapid technological change. Yet true transformation requires more than speed – it requires clarity.
That’s where we come in: connecting architecture, software, and data into one coherent whole.
From strategic design to working systems, we help organizations build their digital future on solid ground.
Architecture. Software. Data.
This is not a slogan, but our foundation.
At spotlight core²code, we translate IT strategies into executable architectures – and architectures into code.
It’s the bridge between vision and realization, between planning and productivity.
Our approach is independent, structured, and holistic.
We think of architecture as the core – not as a layer.
Because only when the foundation is right can sustainable and scalable solutions emerge.
Strategy to life · Architecture to code.
That’s both our mission and our promise.
We look forward to collaborating with those who, like us, believe that innovation begins with clarity.

spotlight core²code is an independent consultancy for IT architecture, software engineering, and data strategy.

Your personal data will not be transferred to third parties for purposes

disclosure is necessary under Art. 6 (1) (f) GDPR and there is no
overriding legitimate interest to the contrary,
