Can you test the product flows with users?

Yes. We can test key journeys and prototypes with users before development. This helps uncover friction, validate assumptions, and improve important flows such as onboarding, activation, and feature adoption.

How do you collaborate with our engineering team?

We work closely with your engineers throughout the project. They receive organised Figma files, reusable components, responsive states, interaction details, and clear documentation to support a smooth handoff.

Do you provide support after launch?

Yes. We can review the implemented product, resolve design issues, refine existing flows, and support future features through a custom project or ongoing design partnership.
