Plaid is the invisible plumbing of modern finance — the API layer that lets apps connect to bank accounts, move money, and verify identity. Its 2023 brand distills that infrastructure metaphor into a clean, daylit visual language: signature teal on near-white, pipe-and-node illustrations that turn abstract data flows into something tangible, and Inter's no-nonsense clarity at every scale.

The result is a design system that says "we handle money, and we take that seriously" without ever feeling stuffy. Generous whitespace, subtle shadows, and restrained color usage project the confidence of a company that powers thousands of fintech products behind the scenes.
