## What technology stack does Santander run in the United States?

Santander's US stack is the group's: Openbank, launched nationally on October 21, 2024, is the first place Santander combined its in-house cloud core, Gravity, with its customer interface, ODS, and it held more than $10 billion of US deposits by October 2026. Gravity is software built in-house that lets the bank run workloads on the mainframe and in the cloud in parallel; Santander says it has moved more than 90% of its IT to the cloud, became the first major Western bank to run 100% in the cloud in Spain in June 2025, runs CIB on Gravity in Google Cloud, and had Gravity ready for Brazil in 2026, with its customer interaction platform live in five markets. US auto lending runs machine-learning credit models on FICO Platform and the Drive dealer platform with AutoFi. The Webster acquisition, closed August 20, 2026, adds a second stack: CEO Christiana Riley plans a core conversion by the end of 2027 and expects $800 million of savings, mainly from merging technology platforms and back-office roles. The US technology bench is COO Luis Massiani, CTO Vikram Nafde and four line-of-business CIOs. AI tooling is group-supplied; the US has not named a cloud provider or AI platform of its own.

## Common questions

### What core banking platform does Santander use in the US?

Openbank in the US runs on Gravity, Santander's in-house cloud-native core banking platform, combined with its ODS customer interface; the US was the first country where the group put the two together. Webster's customers stay on Webster's systems until a core conversion planned for the end of 2027.

### What is Santander's Gravity platform?

Gravity is software Santander built in-house to move core banking from the mainframe to the cloud, running both in parallel so the bank can test in real time without disrupting service. Santander says more than 90% of its IT is in the cloud, Spain moved fully onto Gravity in June 2025, and Santander CIB runs it in Google Cloud.

### When will Santander convert Webster's systems?

US CEO Christiana Riley said at the August 20, 2026 close that there would be no system or brand changes for 12 months and that the core conversion would come by the end of 2027. She expects $800 million of cost savings by the end of 2028, mainly from merging technology platforms and back-office roles.

### Which technology vendors does Santander US name?

FICO, whose platform runs machine-learning credit-risk models in US auto; AutoFi, behind the Drive dealer tools; Dentsu, which built Navigator Global; and Verizon as a distribution partner for Openbank. Group-level providers include Google Cloud for CIB, Microsoft, OpenAI, Anthropic and Google for AI tools.

### Who is Santander US's chief technology officer?

Vikram Nafde, formerly of Webster, is CTO of Santander US for technology shared services, infrastructure and architecture, under COO Luis Massiani, who oversees the joint Technology & Operations function after the Webster acquisition.
