Paris Services

Best Product design and UX company in Paris

Research, design systems and accessibility, judged against usability goals you can measure. Hosn Al Tomoh works with organisations in Paris on product design, agreeing scope, responsibilities and proof of completion for each phase from the start.

Product design starts with research: interviews, usability tests and service maps that show where people struggle. A design system and accessibility standards then keep every screen consistent and usable, in Arabic and English where you serve both.

We work with clients across the Middle East and beyond. For organisations in Paris, that usually means a programme with a Gulf footprint: we plan for your home-market data protection rules and for the GCC laws, such as the UAE and Saudi personal data protection laws, that apply where systems and data will sit.

Work runs in short phases you can review. We strengthen your team with specialist people where you need them, and each phase closes with a demonstration and a decision on what comes next.

Where you already work with systems integrators or vendors, we can deliver in partnership with them, with each party's responsibilities written into the contract.

What has to go right

These are the factors that usually decide whether the programme meets its goals.

  • Research with real users before and after each major design decision.
  • A design system with tokens and components shared by design and engineering.
  • Accessibility checked against WCAG 2.2, including right-to-left layouts.

Where programmes go wrong

Design work goes wrong when it is judged on taste. We agree usability goals you can measure, such as task completion and time on task, and test against them with real users.

We record decisions, responsibilities and test results as we go, so internal audit and regulators can trace every decision and who approved it.

Stages of the work

A phased approach, from assessment to knowledge transfer.

  1. Assess

    We review the current state, the risks and the quick wins.

  2. Plan

    We draw up a phased plan with scope, team, responsibilities and acceptance criteria for each phase.

  3. Deliver and verify

    We deliver in phases and show that each one meets its criteria.

  4. Transfer knowledge

    We document what we built and train your teams to run and change it.
