## Summary

Citi has appointed Sebastian Gnagnarella, formerly Google's director of engineering, as head of applied AI and agent factory. According to an internal memo seen by American Banker, Gnagnarella will oversee the development of agentic AI frameworks and practical applications. This hire follows Citi's earlier recruitment of Brian Saluzzo from Google to serve as Chief Information Officer in March. The moves reflect a broader trend of U.S. banks competing for AI talent from major tech firms to strengthen their leadership in generative and agentic AI.

In the same memo, Citi CTO David Griffiths announced several lateral moves within the bank's AI organization. Aida Filipovic has been named head of responsible AI, focusing on governance and ethical principles. Niamh O'Sullivan is taking on the role of head of AI strategy to set the enterprise roadmap, while Sheetal Chanderkar becomes the chief operating officer for the Groupwide AI team. Citi is also hiring a head of AI-first development to drive native AI product builds.

CEO Jane Fraser stated that AI is accelerating Citi's product development, resulting in a 30% to 40% increase in launch speed. The bank has reduced tech vendor spend by 30% year-over-year by insourcing work, with about 14,000 engineers using Cognition's Devin tool. Industry data from Draup shows AI-related job postings in banking increased 49% year-over-year, rising from 93,686 to 139,819.
