Our story

Pretius operates as a unified force of over 300 specialists backed by 20 years of enterprise market experience. We combine agility with the deep operational maturity required to take full responsibility for enterprise-grade, mission-critical systems running 24/7.

We have evolved beyond traditional software silos. We integrate custom development, modern low-code platforms, AI tools, and elite engineering expertise into one highly efficient software delivery machine.

As strictly technology-agnostic partners, your business problem is our starting point; technology is merely a tool, not the goal. We recognise that in enterprise IT, the delivery process itself often consumes too much time and budget. That is why we eliminate complexity for show and focus entirely on delivering real, measurable business results.

We build software smarter, faster, and without any compromises on quality.

Przemysław Staniszewski

CEO of Pretius / Oracle ACE Pro

In enterprise IT, too much time and budget are consumed by the delivery process itself. We're not interested in complexity for show. For us, technology is a tool, not a goal — and our focus is always on real business value. We've worked with enterprises for years, which allows us to seamlessly plug into corporate structures. And, most importantly, we don't deliver what you ask for but rather what your business truly needs.

Pretius UK — London base, European engineering power

A strategic presence in the British market

Pretius UK is the British branch of Pretius, established to serve UK enterprises with the full depth of Pretius's Oracle and enterprise software expertise — delivered locally, governed under English Law, and structured to eliminate IR35 risk entirely.

Pretius Ltd is a fully registered UK entity, headquartered in London at Ealing Cross, 1st Floor, 85 Uxbridge Road, London W5 5TH. Company No: 147557660. All UK client engagements are governed by English Law, providing jurisdictional security and contractual clarity for British enterprises.

The London–Warsaw hybrid model

Pretius UK operates on a dual-hub model that provides something rare in the British market: the strategic credibility and local accountability of a London-based leadership team, combined with the engineering scale of Europe's largest Oracle APEX hub in Warsaw.

For UK clients, this means:

Local UK contracts governed by English Law — no cross-border complexity
Strategic oversight from London on every project architecture and client relationship.
ACE-level engineering depth from a team of 300+ in-house specialists in Warsaw — immediately available, without recruitment delays.
100% IR35-compliant engagement — every specialist is a full-time salaried Pretius employee; there are no contractors, no off-payroll working arrangements, and no IR35 exposure for UK clients.
FCA/DORA-aware architecture — our UK leadership team understands the regulatory environment British enterprises operate in, and designs solutions that satisfy ICT risk management, operational resilience, and data governance requirements from the outset.

♠ Oracle ACE Director — 1 of 17 worldwide

The "ACE Factor" – why it matters for UK clients

Oracle ACE designation is Oracle's highest formal recognition of technical mastery — awarded through a documented nomination and approval process, not through completing certification courses. There are only 17 Oracle ACE Directors in the world.

One of them — Matt Mulvaney — leads Pretius UK from London.

Having an Oracle ACE Director in London means every UK client project is supervised by someone with a direct line to Oracle's product roadmap, and whose architectural decisions are informed by the deepest available Oracle expertise. This is what we call the "ACE Factor" — and it is our guarantee that your solution is not just delivered, but future-proof.
