FinTech software, built for the rulebook your buyers read first
Zulbera ships regulated fintech products — payment platforms, BaaS-backed wallets, Open Banking dashboards, treasury and reconciliation systems — with compliance architected in from day one. We build under your licence, alongside your compliance team, and design out of PCI scope by default.
Six rulebooks. One technical architecture.
Strong Customer Authentication, payment initiation and account information flows — built to spec, not bolted on.
Bank API aggregation via Truelayer, Yapily, Nordigen — or direct bank integrations for higher-volume products.
Card data architectures using tokenisation gateways (Stripe, Adyen, Checkout). Out-of-scope where possible, audit-ready where not.
Operational resilience, ICT risk management, third-party register and incident reporting — designed in, not retrofitted.
Onboarding flows with Sumsub, Onfido, Veriff. Risk scoring, sanctions screening, SAR/STR reporting hooks.
Data minimisation, lawful basis, retention schedules, DSAR tooling — engineered into the data model, not the privacy policy.
FinTech product shapes we ship
Banking-as-a-Service products
Account, card and payment products built on Railsr, Modulr, Swan or Solaris — with a clean abstraction layer so you can migrate when you outgrow the BaaS.
Open Banking AISP / PISP platforms
Read-only dashboards, payment initiation flows, multi-bank aggregation, consent renewal — with the SCA UX users actually convert through.
Treasury, reconciliation & finance ops
Multi-currency ledgers, double-entry accounting cores, automated reconciliation against bank statements, payout orchestration.
Embedded finance & B2B fintech
Lending APIs, BNPL flows, expense management, virtual cards, vertical-specific neo-banking for SMB segments.
Common founder questions
Do you build under our licence or your own?
Yours. Zulbera is a software studio — we build the technical product. We architect for licence-holders, BaaS-backed founders, and authorised payment institutions, but we are not a regulated entity. We work alongside your compliance officer or recommended advisors when the engagement needs it.
Which BaaS providers do you have experience with?
Railsr, Modulr, Swan, Solaris on the European side. Stripe Treasury, Unit, Treasury Prime on the US side. Truelayer, Yapily, Nordigen, Plaid for Open Banking aggregation. We default to the provider whose licence, geography and product mix match your roadmap — not whichever has the slickest docs.
How do you handle PCI DSS scope?
Default architecture keeps you out of scope: card data hits the tokenisation gateway (Stripe Elements, Adyen Drop-in, Checkout Frames) and never touches your infrastructure. When scope is unavoidable — for example, building a card programme — we design segmented PCI environments with the minimum surface area an auditor will accept.
What does DORA mean for a startup fintech?
DORA applies to financial entities in the EU from January 2025, and to their critical ICT third parties. For startup fintechs that means an ICT risk framework, an incident register, third-party register, business continuity testing, and breach reporting hooks. We build the technical scaffolding (audit logs, incident pipelines, third-party inventories) so your compliance team can operate the policy layer.
How long does a regulated fintech MVP take?
16–24 weeks for an MVP with KYC, payments, and core product flows on top of a BaaS. 9–15 months for a production-grade platform with full compliance hardening, treasury, and the integrations enterprise buyers expect. Compliance work adds 30–50% to timelines vs an unregulated SaaS of equivalent complexity — plan for it from day one.
Can you help us pass a Section 166 / FCA technology review?
We have shipped products that have been through regulator-mandated technology reviews. We can prepare the architecture documentation, access controls, audit logs and resilience evidence regulators expect. We are not a Skilled Person ourselves — we operate as the technical team alongside the appointed advisors.
