We gave them the same documented project brief & analyzed them based on:

  1. Pricing

  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)

We then took all this information and created “The Ultimate UX Agency Benchmarking Report for 2025.”

Based on our global benchmarks, we handpicked a selected list of the 10 best marketplace UX design agencies helping platforms design onboarding, listing flows, seller dashboards, buyer journeys, and payment experiences.

By the end, you’ll know exactly which UX agency aligns with your marketplace product needs & growth goals.

How To Evaluate Your Marketplace UX Agency?

During our benchmarking, we identified three key issues that often arise while choosing the best marketplace UX agencies:

  • Agencies often lack experience designing for both buyer and seller sides of the marketplace.

  • Many designs look good but fail to balance conversion with trust signals or liquidity.

  • Platform scalability and ops handoff aren’t prioritized—causing tech debt in the long run.
