FinTech & Banking Software: Secure, Compliant Solutions
Secure software solutions for banks, insurance companies, and financial service providers – regulatory compliant and future-proof.
FinTech & Banking Software
Software Development for the Financial Industry
Financial service providers must meet strict regulation and the highest security requirements. They also face pressure to digitalize. Meanwhile, many institutions depend on legacy systems that slow innovation.
We combine compliance and innovation in focused financial software:
- Customer portals for banks and insurance companies.
- Compliance automation for KYC and AML workflows.
- AI-powered risk analysis with traceable decisions.
- Secure interfaces for Open Banking and existing core systems.
We also modernize core banking systems step by step without interrupting operations. Our experience spans banks, insurers, asset managers and FinTech startups.
We design for audit trails, encryption and clear authorization concepts. The result is secure, scalable software that can withstand audits and support business growth.
This includes PSD2-ready API integration, automated regulatory reporting and AI-powered fraud detection.
“Compliance is not a sprint add-on—if it arrives after features, rework costs more than a two-week architecture gate up front.”

FAQ
Financial Services IT
Scope, Compliance & Integration
What do you build for banks and insurers?
We build customer portals, compliance automation, reporting and AI-supported risk analysis.
Each solution accounts for regulatory requirements and data protection.
Is the software compliant with financial regulations?
We design audit trails, access controls and documentation into the software.
We also support compliance work for specific regulations, including MaRisk and BAIT.
How much does a financial services software project cost?
The software development cost calculator gives EUR 10,332 – 372,623 excl.
VAT as its non-binding overall range. Portal scope, regulatory controls, audit trails, data sensitivity and core-system integrations determine the concrete result; we refine it after a short assessment.
Can you integrate with our core banking or policy systems?
Yes.
We use APIs or controlled file interfaces to connect common core systems. This keeps data consistent and automates processes.

How software for financial services is built
Four checks: auditable transactions, rights, hosting and existing systems.
1. Name the transactions
Which transaction an auditor must see later. Everything else stays out.
2. Rights per role
Dual control and a log belong to the transaction, not an export added later.
3. Place the data
Hosting and the processing agreement are fixed before the first interface.
4. Connect the core
The core system holds the truth. A second set of master data is not created.
