Our Take

Welcome Max lists 20+ client projects for recognizable brands—Monoprix, Carrefour, eBay, Orange, Royal Canin, Opéra de Paris, Sarenza—with work spanning UX audits, user testing, ethnographic research, and service design. Project descriptions indicate genuine research methodology (guerrilla tests, A/B tests, ethnographic studies, co-design workshops), though detail is limited to brief summaries rather than full case studies with measurable outcomes.

The agency structures its offering around three pillars: research (audit and consulting), service design, and user testing—a clear UX research-first positioning rather than a design execution shop.

The weaker fit is teams needing hands-on UI or build execution, or fully English-language reporting—Welcome Max is a research-first audit and service-design consultancy whose case detail is largely in French.

Key strengths

  • Client roster includes major retail and consumer brands (Monoprix, Carrefour, eBay, Orange, Royal Canin, Opéra de Paris)
  • Research methodology visible across projects: ethnographic studies, guerrilla testing, A/B testing, co-design workshops
  • M-commerce award winner with English and French delivery capability

Good to know

  • Project descriptions are brief summaries without measurable outcomes—ask for detailed case studies with metrics
  • Primary content and most case study detail is in French—confirm depth of English-language reporting if that matters to your team
  • No published rates or team size details—request both early in your evaluation
