A design system and product overhaul for AI voice agents

Retell AI is a leading AI voice agent platform. Their agents sound human, respond in around 600 milliseconds, and handle inbound and outbound calls at scale for teams in healthcare, financial services, logistics, and support. Companies like Pine Park Health, SWTCH, and Medical Data Systems run real volume through it every day.

They came to us with a specific problem. The product had grown fast and was already trusted by serious teams. The interface hadn't kept pace.

We were brought in to do two things. The first is a design system and component library. Not a refresh. A foundation the product and engineering teams can build on for years without relitigating basics every sprint. The second is UX and product work across existing functionality and new features in the pipeline.

We're working directly with one of the founders on this one, which is how the best engagements tend to run. Direction gets set in the room, not over three layers of stakeholder review.
