In 2024, UX and UI design are natural parts of any technology company, and user experience designers finally have a seat at the table. Forward-thinking tech startups are beginning to realize that the user interface (UI), not technology, shapes and differentiates their digital product, whether it’s a website, mobile app, or B2B/enterprise software.

Many big enterprises already have well-equipped digital product design departments with hundreds of user researchers, UX consultants, UI/UX designers, and interaction designers. Smaller companies and startups usually don’t have any UI or UX designers on staff, so they hire user experience agencies.

As startup founder myself, I created this list of high quality UI/UX design agencies from research to UX consulting to end-to-end UI/UX design, to help you find the right design partner for each step of your design journey.
