A Northeast commercial bank that spent 2025 building data, cyber and risk infrastructure for the $100 billion line — and then became the $12.3 billion deal that made Santander a top-20 US bank.
How is Webster using AI?
Webster Bank's independent AI record is short because its independence ended on 20 August 2026, when Banco Santander completed a $12.3 billion cash-and-stock acquisition announced on 3 February. In the two years before, Webster's technology story was about scale rather than models: as it approached the $100 billion asset threshold that would make it a Category IV bank, CIO Vikram Nafde said the bank was investing in data, cybersecurity, digital and regulatory-reporting capability, hiring about 200 people in 2025 including around 25 in technology and cyber, and adding data-governance roles; CEO John Ciulla said the higher bar was 'not our base case' to disappear even if it became less onerous. Product work in 2026 was open banking and automation: an FDX-aligned FI-Streams connector on Plaid's Core Exchange for commercial clients went live in June 2026, and second-quarter internal awards recognised automation that converted more than 100 business online-banking profiles to the treasury platform and Splunk SOAR automation in the security operations centre. Its last annual report, the 2025 10-K filed in February 2026, drew the line plainly: Webster was 'in the early stages of incorporating AI into our business activities to increase employee productivity' and had 'not yet deployed AI-driven systems in critical decision-making or client-facing processes'. The transaction, approved by the OCC in June, the ECB in July and the Federal Reserve on 4 August 2026, folds Webster's businesses into Santander Bank, N.A.; Ciulla becomes CEO of that bank, Webster's Chris Motl leads commercial banking and James Griffin the 500-plus branch network, while Santander's Drew Burchard takes digital banking and the combined company targets an 18% US return on tangible equity by 2028. The AI strategy that now applies is Santander's: more than €1 billion of AI value by 2028, AI tools for all employees from June 2026, and agentic commerce through Getnet.

- Acquired: Santander's $12.3 billion deal announced 3 February 2026 and completed 20 August after OCC, ECB and Fed approvals; Webster's businesses integrate into Santander Bank, N.A.
- Pre-deal technology agenda: data, cybersecurity, digital and regulatory-reporting build-out for the $100 billion Category IV threshold; about 25 of 200 planned 2025 hires in technology and cyber; new data-governance roles.
- 2026 product work: an FDX-aligned open-banking connector on Plaid's Core Exchange for commercial clients (June 2026); internal automation of online-banking conversions and SOC playbooks.
- Leadership in the combined bank: John Ciulla (Webster CEO) becomes CEO of Santander Bank, N.A.; Chris Motl leads commercial banking; James Griffin leads national retail distribution; Santander's Drew Burchard leads digital.
- The AI strategy now in force is Santander's: over €1 billion of AI value targeted by 2028, AI tools for all employees, Getnet accepting AI-agent payments.
- Own AI use was early-stage: the 2025 10-K says AI was being introduced for employee productivity, with no AI-driven systems yet in critical decision-making or client-facing processes; earnings calls in the final year carried no AI remarks.
- Integration: about $800 million of pre-tax cost synergies by 2028, mainly from overhead and technology and operational efficiencies; Santander US CEO Christiana Riley expects a core systems conversion by the end of 2027, with brands and systems unchanged for the first 12 months.
- Scale at close: nearly eight million US customers for the combined bank and a top-five Northeast deposit franchise; Webster had about $85 billion in assets.
What is Category IV readiness: data, cyber and open banking?
Webster's technology agenda before the Santander deal was preparation for crossing $100 billion in assets. CIO Vikram Nafde described a build-out 'in the space of data, cybersecurity, but also digital and the regulatory reporting', with about 25 of roughly 200 planned 2025 hires going to technology and cybersecurity and new roles in data collection, storage and governance. Its 2026 product work was connectivity: an FDX-aligned open-banking connector on Plaid's Core Exchange for commercial clients went live in June 2026, and internal awards in the same quarter went to automation of online-banking conversions and of security-operations playbooks. Under Santander, Webster's businesses fold into Santander Bank, N.A. with Webster CEO John Ciulla running the combined bank.[1][9][13][2]

Integration plan: one platform by end-2027[18]
Santander US CEO Christiana Riley expects a core systems conversion by the end of 2027 and no changes in the first 12 months; the $800 million of cost cuts come mainly from integrating technology platforms and de-duplicating back-office roles. Luis Massiani leads the integration.

What does the public record suggest about Webster's AI strategy?
Analysis by BankingNewsAI from the sources cited on this page. Observations, not advice.
01
Webster's AI future is Santander's ONE Transformation
The relevant questions are now about integration: which Webster systems move to the group's shared platforms and how Santander's AI tools reach Webster's commercial bankers.
02
The Category IV build-out becomes a group asset
Data governance and regulatory-reporting capability built for $100 billion is what a $250 billion Santander US needs; that investment did not go to waste.
03
Open banking on a Plaid-aligned standard is the durable product decision
FDX connectivity for commercial clients will outlast the brand and is the kind of API layer agentic finance will rely on.
04
Watch who owns digital
Santander's Drew Burchard leading digital for the combined bank means Openbank's approach, not Webster's, sets the customer-facing AI roadmap.
What happened to Webster Bank?
Banco Santander completed its $12.3 billion acquisition of Webster Financial on 20 August 2026, after OCC, ECB and Federal Reserve approvals. Webster's businesses are being integrated into Santander Bank, N.A., with former Webster CEO John Ciulla as its CEO. Everyday banking for Webster customers was unchanged at closing.
Did Webster have an AI strategy of its own?
Its public technology agenda before the deal was preparation for the $100 billion Category IV threshold: data, cybersecurity, digital and regulatory-reporting investment, with roughly 25 technology and cyber hires among about 200 planned in 2025, plus open-banking connectivity and internal automation in 2026. The AI strategy that now applies is Santander's, which targets more than €1 billion of AI value by 2028.
