Why partner with Neontri

End-to-end banking expertise

From system audits and IT roadmaps to architecture, development, and post-launch support, Neontri covers the work banking software needs end to end: core modernization, mobile apps, data platforms, payment processing, and AI-powered compliance. One partner, not five vendors.

Deep regulatory knowledge

With extensive experience across retail, banking, and fintech, Neontri guides its clients through the unique challenges of each sector, including regulatory compliance, data security, and legacy modernization.

Banking consulting & technology roadmaps

We assess your current systems, then turn the findings into a phased roadmap for APIs, cloud integration, and data architecture. Whether you are moving off legacy core banking, consolidating vendor-heavy infrastructure, or preparing your data layer for AI, we map the path before we build.

Security-first for regulated finance

Banking software handles high-volume transactions and sensitive financial data, so security is built into the delivery process from the start. We use gated releases, automated SAST/DAST scans, code reviews, and penetration testing before major releases, backed by ISO 27001 and ISO 22301 certification.

Proprietary framework

Neontri Enterprise Application Framework (NEAF) gives mobile banking teams a secure architecture foundation before feature work begins. It includes mutual TLS encryption, PKI certificate management, multi-factor authentication, protected data storage, threat detection, and jailbreak prevention.

Proven track record

18+ banking and fintech clients, including Visa, PKO Bank Polski, mBank, PEKAO, Millennium, KIR, Blik, and Ramp. Our work spans the IKO mobile banking app for 8 million users, a Data Hub that offloads 70 million records daily, and a PSD2 hub connecting 300 Polish banks, delivered six months ahead of schedule.

The results have earned two Finovate Best of Show awards and Retail Banker International recognition for the world’s No. 1 banking app.
