About us

As part of an institution with a long tradition, we want to be open to change and progress. With AHOI, we're creating an API platform to jointly develop new solutions and bring them to the market. Through our exchange with the entire Sparkassen-Finanzgruppe, we have many years of experience in banking and financial interfaces and know what we're doing. Together we want to experiment, learn and grow.

By actively managing the community of fintechs and developers and leveraging our deep regulatory understanding, we're in the perfect position to collaboratively share ideas, to make connections and to develop new product approaches.

Our ecosystem

Over the past two years, working together with our cooperating partners, we’ve developed an ecosystem both beyond and within the Sparkassen-Finanzgruppe (SFG).

New product ideas are developed quickly and effectively according to customer needs and must also be supported communicatively and strategically in the SFG.

One important goal of this is to work together with fintechs and to network with innovation initiatives in the SFG.

From API to developer portal

Open Banking is a top priority of our work in the Sparkassen Innovation Hub. In doing so, we’re following the vision of expanding the AHOI API platform into a developer portal for the Sparkassen-Finanzgruppe. This would also make it a port of call for fintechs and other third parties.

The welcome page for the recently launched XS2A (Access to Accounts) Sandbox by Finanz Informatik marks the first step towards this developer portal. The present aim is to consolidate contact with the TPPs (third-party providers) in one place. With a BaFin authorization as an account information service (AIS) or payment initiation service (PIS), the S-Hub can support fintechs and other TPPs in meeting regulatory requirements. In this way, it can become the enabler of many other use cases for the Sparkassen-Finanzgruppe.


We support you in integrating our API and other features. Together we can develop new products – within the Sparkassen-Finanzgruppe or outside of it.
