Userlutions
Berlin, Germany
About
Berlin UX agency specializing in usability testing, user research, and UX design, with a proprietary testing platform (RapidUsertests).
Our Take
Three detailed case studies document end-to-end UX process—Coca-Cola Europacific Partners (B2B e-commerce platform across 13 countries since 2017, embedded in agile sprints with brainstorming, wireframes, high-fidelity prototypes tested with real users), E.ON (design thinking with guerrilla user research, expert review, ideation workshops, and creative focus groups producing 70+ ideas for a meter-reading app), and Vaillant (long-term partnership combining UX design, continuous usability testing, and stakeholder coaching).
The agency fields 17+ named UX specialists with dedicated Senior Researchers and Team Leads, plus runs RapidUsertests as a proprietary crowd usability testing platform. Claims market leadership in usability testing in Germany.
Best for enterprises needing dedicated usability testing, user research, and research-driven UX design—particularly German B2B and B2C companies where validated design decisions matter.
Key strengths
- Coca-Cola case documents 7+ year embedded partnership across 13 countries—brainstorming, wireframes, high-fidelity prototypes tested with real users before development
- E.ON case shows full design thinking process: guerrilla research, expert review, ideation workshops, creative focus groups, and clickable prototype—with named client testimonial
- 17+ named UX specialists with dedicated Senior Researchers and Team Leads, plus a proprietary testing platform (RapidUsertests)
Good to know
- No hourly rate published—request pricing early to assess fit with your budget
- Vaillant case mentions continuous UX tests but published case studies don't include specific measurable outcomes—ask for conversion or adoption metrics from past engagements
