Security and compliance by design
Security-by-design architectures aligned with PSD2, PCI-DSS and GDPR. Encryption, traceability and audits built in, not patched on at the end.

Custom software development for Fintech
We build secure, scalable financial platforms —payments, digital banking, scoring, wallets— with the regulatory rigour the sector demands and the speed your business needs.
THE CHALLENGE
The challenges of Fintech
Fintech software operates under constant regulatory and security pressure, where a failure carries direct financial and reputational cost. It needs regulatory rigour, traceability and an architecture that scales without compromising trust.
- Regulatory compliance (PSD2, PCI-DSS, GDPR)
- Financial data security
- Scalability under transaction spikes
- Integration with payment gateways and core banking
- Time-to-market without compromising rigour
How we help you
In fintech, a bug isn't just a bug: it's money, trust and a fine from the regulator. We build custom financial software with security and compliance from the very first commit, without sacrificing time-to-market. From a validated MVP to the platform that processes millions of transactions, with a senior team that has already been in the trenches of the sector.
Frictionless financial integrations
We connect gateways (Stripe, Adyen, Redsys), core banking, KYC/AML and open banking with robust, well-documented APIs.
Scale for transaction spikes
Systems that withstand campaigns, payroll runs and month-end closes without falling over, with observability to see what's happening in real time.
From MVP to production, fast
We deliver the first slice of value in weeks and evolve it with frequent, tested releases. No surprises.
WHAT YOU GAIN
Custom development, results-driven
- A senior team that delivers value from the very first weeks, with no ramp-up
- Software shaped around your process, instead of your process squeezed into a template
- Architecture designed to scale and integrate, without a rewrite two years in
- Tested, reviewed and documented code
- Full ownership of the product and the know-how
FAQ
Frequently asked questions
Do you build in compliance with PSD2, PCI-DSS and GDPR?
Yes. We work with security and compliance by design: encryption in transit and at rest, secrets management, traceability and access controls. We prepare the system for audits and certifications from day one.
Can you integrate payment gateways and core banking?
Yes. We integrate gateways such as Stripe, Adyen or Redsys, KYC/AML providers, open banking (PSD2) and core banking through secure, well-documented APIs.
How long does a fintech MVP take to be ready?
It depends on scope, but we usually deliver a first functional, testable slice in 8-12 weeks, prioritising the flow that creates value and compliance from the start.
How do you guarantee the security of financial data?
With defence in depth: encryption, least privilege, managed secrets, monitoring, security testing and code reviews. Security is part of the process, not an add-on.
Do you work with an MVP or a product already in production?
Both. We launch MVPs from scratch, prioritising the flow that creates value, and we also step into existing products to stabilise, scale or evolve them.
What technology stack do you use?
We choose the stack based on the problem, not the other way around. On the web layer we work with React, Next.js and TypeScript; on the backend, with Python (Django and FastAPI) and Node. We prioritise maintainability and ecosystem over hype, and we explain why we picked each piece before writing any code.
How much does custom development cost?
It depends on the real scope, and you should be wary of anyone quoting a number before understanding it. What we do quickly is bound it: in a first conversation we identify the first slice that delivers value and give you a range with explicit assumptions, so you decide with information rather than with a figure pulled out of the air.
Is the code ours?
Yes. The code, the infrastructure and the know-how are yours from day one. We document and hand everything over so your team can carry on with no strings attached.
Shall we build something that scales, together?
Tell us about your project. We'll get back to you with a concrete plan and a senior team — not a generic quote.
