In their own words

About the company & team

The UI Platform team, known as Sail, builds the foundations that support Stripe's Dashboard and many of Stripe's other user interfaces. The Sail UI team owns Stripe's design system, helping Stripe engineers create consistent, accessible, performant, and high-quality experiences at scale.

We build and maintain reusable components, design tokens, theming capabilities, documentation, and developer tooling used by engineers and designers across Stripe. We are currently focused on two major projects. First, we are building Sail for Agents: the generation infrastructure, documentation systems, agent integrations, and automated quality checks that help AI coding agents build high-quality Stripe interfaces safely and consistently at scale. Second, we are evolving the visual language of the Dashboard, one of Stripe's largest UI surfaces, while modernizing its underlying codebase.
