Open Banking

Accelerate your Open Banking strategy with reliable and secure APIs

We design APIs that are easy to integrate, well-documented and ready to scale — enabling your teams to innovate faster and with confidence. Our approach combines engineering rigour, lean delivery and a strong focus on the developer experience.

Your main challenges

API integrations that take too long

API integrations often stretch over weeks, slowing down new product launches. This delay leads to missed opportunities and impacts growth in a market where agility is critical.

Technical debt building up, and a developer experience that needs a reset

Incomplete documentation, limited support and poor developer experience create friction, rework and a lack of trust. Teams stall: less innovation, more fixes, and partners hesitate to engage.

Heavy legacy systems that are difficult to evolve

Monolithic architectures and ageing platforms limit the ability to shift towards more open models such as API-as-a-product, embedded finance or strategic partnerships. The adaptation effort becomes a barrier to an effective open finance strategy.

Our approach

Redesign architectures to maximise adoption

We start from the integrator journey and developer pain points to rethink API exposure, governance and onetization. The result: clearer, more open and easier-to-adopt platforms.

Industrialiser la fiabilité et la sécurité.

Nous avons standardisé chaque étape de la conception à la supervision : standards API (REST, OpenAPI, GraphQL), tests automatisés, monitoring continu, sécurisation avancée. Grâce à cette maîtrise outillée, chaque livraison atteint un niveau de qualité et de fiabilité constant, mesurable et reproductible.

Move fast without compromising quality

In a few weeks, we deliver a first version ready to test with your teams. Our user-centred approach and engineering discipline ensure APIs that are robust, well-documented and built to scale.
