"Nine published success stories follow one pattern: UX&I builds the client's internal UX capability—a discovery program, a UX-writing practice, a design-system governance model—then hands it off, several ending with the client's own team taking over.

Strengths and watch-outs
Both upsides and risks, straight from our editorial assessments.
Bonanza Studios
✓ Strengths
- •5/5 Clutch rating across 60+ clients with named testimonials from CPOs, CTOs, and strategy leads at verifiable companies
- •Structured engagement model with clear timelines—7-day prototype, 2-week design sprint, 90-day digital acceleration—reduces scope ambiguity
- •Active thought leadership including an AI MasterClass, UX for AI podcast, and published know-how content on digital readiness
⚠ Watch-outs
- •Case studies focus on business outcomes and shipping speed—no visible UX research, usability testing, or design iteration artifacts; ask for process details if UX rigor matters for your project
- •Core team is 2 people plus an execution network of specialists—confirm who will be assigned to your project and their availability for the full engagement
- •Strong startup and scaleup portfolio but limited evidence of large-enterprise or regulated-industry work beyond UniCredit and BEUC—verify relevant experience if your context demands it
UX&I GmbH
✓ Strengths
- •Ranked the most-recognized UX firm in Germany (2025 German UPA report), backed by 37 staff across five offices since 2014 and TÜV Rheinland certification—an established, low-risk vendor.
- •Works at the top of the German enterprise market—10 of the country's 15 largest companies, including Mercedes-Benz, Porsche, and Allianz—so large-organization procurement and complexity are familiar ground.
- •Structured for multi-year transformation over one-off projects: engagements like One Data and METRO ran three or more years.
⚠ Watch-outs
- •No product-level UX metrics (conversion, task completion, adoption) in published work—ask for outcome evidence if that's how you'll judge success.
- •The website and published case studies are in German, though the client base includes US tech firms—request English-language case studies if you need to evaluate the work yourself.
- •The model centers on strategy and enablement at €150-199/hr—if you need hands-on production of a fixed screen set, clarify who executes and the scope up front.
