We gave them the same documented project brief and evaluated based on:

  1. Pricing

  2. Engagement Model

  3. Payment Structure

  4. Timeline

  5. Team Structure

  6. Number of Employees

  7. Domain Expertise

  8. Depth of Service

  9. Business Thinking (Conversion Rate Optimization)

  10. Client Collaboration

  11. Dev Handoff Process

  12. Work Setup (Remote/Hybrid/In‑Office)

From this, we created The Ultimate UX Agency Benchmarking Report for 2025. Based on our global benchmarks, we hand‑picked a list of the 10 best interaction-heavy UI design agencies—those known for creating deeply engaging, interaction-led interfaces.

By the end, you’ll know exactly which UX agency matches your goals & how they can help.

How To Evaluate Your Agency?

During our benchmarking, these three critical issues emerged when evaluating interaction‑heavy UI design agencies:

  • The agency fails to structure interaction logic for scalable systems or design systems.

  • Communication breakdowns between designers, animators, and engineers lead to misaligned behavior in UI.
