Frequently Asked Questions

Q1. Which company is best for UI/UX design in the USA in 2026?

There isn’t one “best” for every team. It depends on what you’re solving for: deeper research, quicker iteration, enterprise-scale UX, or a partner that can stay involved through build and release. El-Digital and Musk Deer is a strong fit for a partner that covers UX/UI for web and mobile, information architecture, usability testing, redesign work, and accessibility-focused UX.

Q2. What services do top UI/UX design companies usually provide?

Most agencies cover the core path from discovery to design: user research, information architecture, user flows, wireframes, prototypes, UI design, and usability testing. Many also help with redesigns, accessibility checks, and clean handoff packages that developers can implement without guessing.

Q3. What should I ask before hiring a UI/UX agency?

Ask how they run a project end to end, who actually owns research and UI day to day, and what “testing” means in their process. Get clear on how they approach accessibility, whether they can build or extend a design system, and what you’ll receive for developer handoff.

Q4. How do I choose the right UI/UX company for my product?

Start with your product type (B2B platform, consumer app, ecommerce, SaaS), then match for experience in similar workflows. Review recent case studies, confirm the exact team working on your account, and ask what deliverables you will get.
