What We Offer in terms of Open Banking & Open Finance Consulting

Open Banking Strategy & Product Development

We help companies identify where Open Banking can create genuine business value. This includes evaluating payment use cases, financial data applications, embedded finance opportunities, customer journeys, business models and commercial partnerships. We translate these opportunities into realistic product concepts, implementation priorities and go-to-market plans.

Payment Initiation & Pay-by-Bank Solutions

We support the design and implementation of payment experiences based on payment initiation services and account-to-account transfers. Our work covers business requirements, provider selection, payment flows, checkout integration, customer experience, reconciliation and operational considerations. We help clients assess when Pay-by-Bank makes commercial sense alongside cards and other payment methods.

Account Information & Financial Data Solutions

We help companies use appropriately accessed account and transaction data to improve onboarding, financial analysis, customer experiences and business processes. Our support includes AIS use-case design, provider selection, API integration planning, data quality, permission management and analytics applications.

Open Finance Strategy & Regulatory Readiness

Open Finance creates opportunities to develop financial products using a broader range of customer-permissioned financial information. We help organizations assess potential use cases, data partnerships, governance requirements, operational models and the implications of evolving European regulation, including the FiDA initiative.

How We Work?

1

Identify the Business Opportunity

We start with the business model, target customers, existing financial infrastructure and the problem to solve. We assess whether Open Banking or Open Finance can create measurable value and identify the most relevant payment or data-related use cases.

2

Design the Solution & Partner Model

We define the proposed customer journey, service model, data or payment flows, provider requirements, operational dependencies and regulatory considerations. We evaluate available partners and translate the concept into a commercially and technically viable approach.

3

Support Integration & Implementation

We work with client teams and external providers to prepare requirements, coordinate integrations, support product delivery and address issues arising across APIs, security, user permissions, payment flows, data handling and operations.

4

Optimize & Scale

Following implementation, we help evaluate product performance, operational efficiency, customer experience and future development opportunities. We support further integrations, provider improvements, additional markets and new Open Banking use cases.

Open Banking & Open Finance Consulting

Open Banking is a product opportunity, not just an API integration

Connecting to a banking API is only one component of a successful Open Banking project. The real challenge is combining customer value, a viable business model, reliable data or payment flows, regulatory requirements and operational processes. z3x helps companies look beyond the technical connection and design solutions that fit their products, customers and commercial objectives.

From payments and account data to the next generation of financial services

Open Banking already enables practical applications in payments, account aggregation, financial analysis and customer onboarding. Open Finance may expand the range of accessible financial information and support new service models as regulation and infrastructure evolve. We help companies build around today's opportunities while keeping their architecture and product strategy adaptable to future developments.

Frequently asked questions

Open Banking typically focuses on access to payment-account information and payment initiation through regulated interfaces. Open Finance is broader and concerns the controlled sharing and use of additional types of financial information. The precise scope, rights and obligations depend on the relevant legal framework and service model.

z3x is a FinTech consulting and implementation-support partner, not an Open Banking API platform. We help clients design solutions, evaluate and select providers, plan integrations, coordinate implementation and develop business models around regulated services supplied by appropriately authorized partners.

Yes. We work across payment initiation, account information, analytics, product strategy, provider selection, regulatory considerations and technical implementation support. The scope is adapted to the client's business model and existing infrastructure.
