Client Testimonials

Trusted by Fintech Leaders

The teams who've shipped with us.

“

DevGenome delivered a production-grade payment processing system that handles millions of transactions monthly. Their deep understanding of PCI DSS requirements and card network protocols is rare — and they delivered on time without compromise.

European Payments Institution
“

We brought DevGenome in to build our entire card issuance platform from scratch. 6 months later, we were live in 4 markets with 100K+ active cards. The team understood both the technical and regulatory sides perfectly.

“

Their AI-powered fraud detection engine reduced our false positive rate by 65% within the first quarter. DevGenome combines strong ML engineering with real fintech domain knowledge — a combination that's extremely hard to find.

FAQ

Common Questions from Fintech Teams

Answers to the questions we hear most from banks, EMIs, and fintech startups.

It depends on scope and integration complexity. A basic payment gateway integration typically takes 6–10 weeks. A full-stack, multi-currency gateway with compliance workflows, fraud detection, and core banking integrations is usually 4–6 months. We provide a detailed technical scoping within 2 weeks of your inquiry.
Yes. We build with PCI DSS compliance as a first principle, not an afterthought. We can help your organization achieve PCI DSS Level 1 or 2 compliance, including cardholder data environment design, tokenization architecture, network segmentation, and preparation for Qualified Security Assessor (QSA) audits.
Absolutely. We have deep experience integrating with major core banking platforms (Temenos, Mambu, Thought Machine, Finacle), payment networks (Visa, Mastercard, SEPA, SWIFT), and PSPs (Adyen, Stripe, Checkout.com). We also build custom middleware layers for legacy systems that lack modern APIs.
Yes — this is our primary market. We understand regulatory requirements for EMIs, payment institutions, and licensed banks across the EU (under PSD2/PSD3), UK (FCA), and international frameworks. We can work within your compliance guardrails and provide documentation for regulatory reviews.
We work on three models: (1) Fixed-price project delivery with clear milestones, (2) Dedicated engineering team (staff augmentation) embedded in your product org, and (3) Technical advisory and architecture consulting. Most clients start with a scoped project and transition to a long-term team arrangement.
All engagements are covered by mutual NDAs from day one. We operate GDPR-compliant development environments, use encrypted repositories, and implement strict access controls. All IP created during the engagement is fully transferred to you upon project completion. We never reuse client-specific code across projects.
