Secure software solutions for banks, insurance companies, and financial service providers – regulatory compliant and future-proof.
FinTech & Banking Software
Financial service providers face unique challenges: strict regulation (BaFin, MiFID II, PSD2), highest security requirements, and pressure to digitalize. At the same time, many institutions struggle with legacy systems that slow down innovation.
We develop software solutions that combine compliance and innovation: customer portals for banks and insurance companies, compliance automation for KYC and AML, AI-powered risk analysis, and secure interfaces for Open Banking. We modernize existing core banking systems step by step – without operational interruption.
Our expertise in the financial sector spans projects for banks, insurance companies, asset managers, and FinTech startups. We understand the requirements for audit trails, encryption, and authorization concepts. From PSD2-compliant APIs through automated regulatory reports to AI-powered fraud detection: we deliver secure, scalable solutions that withstand audits and drive your business forward.
“Compliance is not a sprint add-on—if it arrives after features, rework costs more than a two-week architecture gate up front.”
Björn Groenewold, CEO, Groenewold IT Solutions
