Our story

Pretius is an IT company with over 20 years of experience working with large enterprises. We combine agility, technical expertise, and a deep understanding of complex corporate environments.

Our focus is on building tailor-made applications — using both traditional technologies and modern low-code platforms like Oracle APEX, which we've been working with long before it became a trend.

We start with real business needs and choose the right technology to match — not the other way around. We deliver fast, smart, and without unnecessary complexity, always prioritizing business value over technical showmanship.

Przemysław Staniszewski

CEO of Pretius / Oracle ACE Pro

Our goal is to deliver IT smarter, faster, and within budget. When possible, we use low-code — we were doing it before it was cool. We understand how corporate structures work because we’ve worked with them for years. That’s why it’s easy for us to plug into your processes. And most importantly — we don’t deliver what you ask for. We deliver what you actually need. For us, IT always walks hand in hand with business.
