Licensed German bank consolidates its SEPA Instant payments on ACI Connetic, the cloud-native platform that brings payments processing, orchestration, fraud prevention and payments intelligence together in one system

OMAHA, Neb.--(BUSINESS WIRE)--Sep. 24, 2026-- ACI Worldwide (NASDAQ: ACIW), an original innovator in global payments technology, today announced that Solaris, Europe’s leading embedded finance platform, has gone live on schedule on ACI Connetic, ACI’s unified cloud-native platform for intelligent payments orchestration.

The milestone marks the successful completion of the first phase of Solaris' payments modernization initiative. By consolidating its SEPA Instant payments infrastructure onto ACI Connetic, Solaris has strengthened its ability to scale, innovate and adapt in a rapidly evolving payments landscape.

It paves the way for the continued modernization of Solaris' payments infrastructure, as Solaris expands its adoption of ACI Connetic as part of its long-term transformation strategy.

Instant is now the baseline for euro payments. Under the EU Instant Payments Regulation, payment service providers in the eurozone must receive instant credit transfers, send them at no higher price than a standard transfer, and offer a check of the payee’s name against the account before the payer authorizes a transfer. That turns SEPA Instant from a premium service into everyday volume that runs around the clock and settles in seconds, with fraud checks done inside the same window. ACI Connetic handles that load in one cloud-native architecture that combines payments processing, fraud prevention, payments intelligence and orchestration, so a bank can add capacity and new services without stitching separate systems together.

Solaris holds a full German banking license and runs accounts, cards, lending and payments for fintechs, digital brands and multinationals that build financial products into their own customer experiences. Those partners count on Solaris to move money on their behalf, which makes instant payments part of what they buy from it. Solaris selected ACI Connetic as the foundation of its payments modernization strategy. Together with majority shareholder SBI Group, it has also set out plans to develop its platform into pan-European financial infrastructure.

“Banks across Europe are rebuilding their payments around instant, and the ones moving fastest are making it a platform decision,” said Thomas Warsop, president and CEO of ACI Worldwide. “Solaris runs payments for an entire ecosystem of partners, so it needs infrastructure that grows with them. Bringing SEPA Instant onto ACI Connetic gives Solaris that foundation for its next phase of growth.”

“Going live on ACI Connetic is an important milestone in evolving our platform infrastructure,” said Steffen Jentsch, CEO of Solaris. “As Solaris matures into a Financial-Platform-as-a-Service provider, ACI Connetic gives us the scalable, robust foundation we need to deploy AI-driven, highly resilient payment processes that meet the highest European regulatory standards our partners and their customers expect.”
