ACI Connetic is the platform behind ACI’s intelligent payments orchestration strategy, introduced in 2025 as the industry’s first unified cloud-native platform bringing account-to-account payments, card payments and AI-powered fraud prevention onto a single architecture. ACI’s acquiring, issuing, ATM and self-service banking solutions process more than 300 billion card transactions annually. The acquisition accelerates ACI’s existing Connetic for Cards roadmap, bringing planned card switching capabilities to market sooner.
Purchase transactions on the global card networks are projected to reach more than 1.1 trillion in 2029, a 43 percent increase over 2024. At the same time, institutions are running more payment rails in parallel, and card authorization at many banks and processors still relies on architecture designed before cloud computing was an option. A common modernization approach has been to wrap an existing switch in new interfaces rather than rebuild what runs underneath. ACI built ACI Connetic to address that directly.
Founded in 2018 in the United Kingdom, Cranium Ventures has key operations in Singapore and Malaysia and developed SYNAP, a microservices-based card switching framework that runs in cloud, on-premises and hybrid environments. Under the agreement, ACI will acquire Cranium Ventures’ technology, intellectual property and commercial relationships, and Cranium co-founders Ashraf Dimitri and Tony Horrell will join ACI, bringing decades of experience delivering payment switching technology to financial institutions and processors worldwide. Dimitri founded Oasis Technology in 1989 and was a lead architect of IST/Switch, a global payment switch. Horrell has founded and exited multiple payment industry companies and has also held senior roles at leading payments technology companies, including Visa, First Data, and ACI Worldwide. Cranium’s broader technical team also brings experience implementing and operating SYNAP, including at two of the world’s largest processors.
“Card processing is one of the hardest modernization problems left in payments, and we have been working on it for years,” said Thomas Warsop, President and Chief Executive Officer, ACI Worldwide. “Financial institutions need more than a switch. They need intelligence embedded throughout the payment lifecycle, and that is what we built ACI Connetic to deliver. ACI Connetic for Cards is already in market, and Cranium Ventures moves that work forward faster. It will further strengthen our competitive position in cloud-native switching and payment solutions, consistent with our focus on expanding our strategic growth platform.”
“Modern switching has to hold up in environments where the tolerance for failure is close to zero. That is what we built for,” said Tony Horrell, Chief Executive Officer, Cranium Ventures.
“We set out to answer whether a microservices switch could hold up under the volumes and the certification demands that real card processing puts on it, and we put it into production,” said Ashraf Dimitri, Chief Technology Officer, Cranium Ventures.
Financial terms were not disclosed. The transaction is subject to customary closing conditions and approvals and is expected to close in the third quarter of 2026. ACI will support Cranium Ventures’ existing SYNAP customers following close.
