BNY

BNY safeguards $55.8 trillion in assets. Its relationship managers, operations leaders, and executives work across offices, client sites, and airports. Yet the intelligence they relied on sat in separate systems. Preparing for a single client meeting meant moving between tools and piecing the picture together by hand.

Eliza is BNY's internal AI platform. Fantasy partnered with BNY to shape its future vision, a mobile-first experience that brings client relationships, portfolios, meeting preparation, and compliance into one view and anticipates what a banker needs before they go looking for it. That work grew into the coded, AI-native design system behind the platform, changing how BNY's own design team ships.

Fantasy delivered an AI-native design system with a three-layer token architecture, and a library of more than 60 production-ready components, documented for AI code generation rather than for a static handoff.

Around it, we built a git-native way of working, with instruction files that encode the design system's knowledge for AI coding tools. BNY's design team moved into their development environment and now ship production code directly.

OpenAI featured Eliza in its own customer story, "BNY builds AI for everyone, everywhere," a measure of how central the platform has become to the bank's AI strategy. The vision work was also named a finalist for a Financial Communications Society award in Visual Identity and drew coverage in Fortune. Inside BNY, the clearest proof is adoption: the engineering team builds on Fantasy's design system, and the design team now works IDE-native on the foundation we delivered.
