## What technology stack does State Street run?

State Street's technology centres on State Street Alpha, the front-to-back platform that joins Charles River Development's cloud-based front office to the bank's middle- and back-office services; Alpha drove nearly half of 2024's $2.3 trillion of new servicing assets. At Snowflake Summit 2023 State Street Alpha said it was partnering with Snowflake to build AI and machine-learning capabilities, and deep-learning anomaly models on the Alpha Data Platform cut flagged data exceptions from over 31,000 to about 4,000 while catching all 250 true errors. The cloud estate began with a Microsoft Azure wealth data platform in 2020 and expanded through a 2023 AWS alliance; the July 2026 deck targets about 80% of applications on modern cloud platforms, up from about 40%. On top sit AgenTx and an AI foundry (2026), an internal agentic platform, AI development tools for every developer with a 30-40% productivity target, and a copilot platform for employees; in 2024 the bank named Microsoft Copilot. Trading clients use the LINK desktop, which in 2025 added EMAlpha's multilingual AI. Global CTO Christopher Herringshaw (August 2026) covers infrastructure, architecture, cloud, AI and application development. State Street has not published its technology budget.

## How is State Street modernising its technology?

The July 2026 plan pairs a core agentic platform with faster legacy-code modernisation and a cloud migration from about 40% to about 80% of applications on modern platforms. ([State Street (SEC filing)](https://www.sec.gov/Archives/edgar/data/93751/000009375126000387/stt2q26earningspresentat.htm))

Woods said in September 2026 that cash processing is 'wringing out a significant amount of manual interfaces' in sanction screening, reconciliations and auto-matching, which 'increases controls and speed of delivery for clients'. ([Investing.com](https://investing.com/news/transcripts/state-street-at-barclays-conference-growth-ai-and-margin-gains-93CH-4900063))

Leadership changed with it: CTO Andrew Zitney became CIO in July 2025, Christopher Herringshaw joined as global CTO in August 2026, and Mostapha Tahiri became president of State Street Alpha in September 2026.
