Pretius

Pretius is a Warsaw-based software delivery firm founded 20 years ago with over 300 specialists across Poland and the UK. The company positions itself as technology-agnostic, starting from business problems rather than platform preferences. Leadership includes founder Rafał Lenczewski and CEO Przemysław Staniszewski (Oracle ACE Pro), alongside Matt Mulvaney as CEO of the UK operation (one of only 17 Oracle ACE Directors globally specializing in APEX). The firm has delivered over 1,000 projects, with 93% of clients becoming long-term partners, some collaborating for more than 20 years.

Services and capabilities

Pretius structures its offerings around three core competencies: custom development, low-code platforms (primarily Oracle APEX and Mendix), and AI. The company highlights rapid delivery of functional prototypes and proof-of-concepts, claiming to produce working demos in weeks or even during initial meetings. Custom development spans sales process automation, legacy modernization, identity and access management, business process automation, and bespoke CRM systems. Low-code work focuses heavily on Oracle Forms migration to APEX, Oracle APEX workflow design, and Mendix implementations. The AI practice includes computer vision and semantic search (their MonkeyJar product).

Measurable outcomes appear throughout their case work. For a Greek health insurance provider, they migrated a legacy system to Oracle APEX, cutting tasks that previously took days to a few minutes. At Sweco (Netherlands), an infrastructure management app now serves 120+ European cities after modernization work. A telecom company's reserve creation process dropped from 15 days in Excel to 20 minutes in the new system. T-Mobile Poland gained 270,000+ new customers after Pretius built a unified CRM on a 350-module microservice architecture, resolving a fragmented three-system environment. TVN's VOD platform, after migration to AWS, achieved 30% reduction in operational costs and now handles 60+ million monthly views.

The firm operates ISO 27001 certified, meeting enterprise security standards. Cloud migration work includes lift-and-shift operations to AWS and Oracle Cloud Infrastructure deployments.

Notable work

T-Mobile Poland represents a flagship engagement spanning over 10 years. Pretius analyzed requirements and developed a CRM consolidating three legacy systems into a single source of truth for sales consultants, improving efficiency and maintenance. The architecture uses 350 microservices and eliminated the need to shut down the environment during updates.

TVN's Player.pl platform migration to AWS solved a specific problem: the need to introduce paid subscriptions and e-commerce while handling unpredictable traffic spikes. The cloud redesign reduced operational costs by up to 30% and proved capable of managing 60+ million views monthly within months of launch.

Other named clients include Munich Re HealthTech (cost reduction on licensing), Profitowi (sales process standardization), Sweco (municipal infrastructure platform supporting 120+ cities), Van Group (custom freight management system with route planning and cargo tracking), and Play (offer verification reduced to 30 seconds from hours). Santander's automation work freed 2–3 hours weekly per recruiter for higher-value activities.

How they work

Pretius emphasizes process-lean delivery and incremental value. The approach combines custom development, low-code platforms, and AI into a single engagement model. The firm operates dual hubs in Warsaw and London, allowing proximity to both engineering talent and client markets across Europe. Engagement starts with strategic analysis and business problem definition before technology selection. Team structure appears flexible: the company offers dedicated teams, staff augmentation, and fixed-scope projects. Communication includes a dedicated project manager per engagement (noted in client feedback). Board-level involvement is visible—Bartosz Zacharuk (CTIO) oversees delivery and operations; Kamil Rostkowski (COO) handles financial strategy and operations. The founding team and leadership retain hands-on roles in Oracle APEX and low-code strategy.

Team and credentials

Pretius employs 300+ specialists. Leadership credentials are substantial: Przemysław Staniszewski holds Oracle ACE Pro (APEX), Matt Mulvaney is one of 17 global Oracle ACE Directors specializing in APEX, and the team includes 7 recognized Oracle ACEs overall. Rafał Lenczewski founded the firm with decades of experience in telecom, media, and banking. The firm holds ISO 27001 certification. Matt Mulvaney authored Pretius Developer Tool and Pretius AI Forms to APEX Assistant, both widely used in the APEX community. The organization speaks multiple languages and operates in both Warsaw and London, with established processes for cross-continent delivery. Client testimonials emphasize technical depth paired with business acumen—CIOs and CTOs repeatedly note the team's focus on business outcomes over technological complexity.
