LION+MASON
London, United Kingdom
About
Creating meaningful experiences so businesses can leverage effective product design.
Our Take
Eight published case studies walk through a recognisable consulting process—UX audit, benchmarking, journey mapping, user interviews, prototyping and user testing—for named clients including Best Western, Allianz, Johnson & Johnson and Barnett Waddingham.
Results are uneven: the Best Western redesign cites +32% year-on-year online revenue and a +20% conversion lift over a 14-week build, and Barnett Waddingham carries a partner-attributed ~90% new-business win rate, but the Allianz and several other studies describe activity and "validated solutions" without business metrics, and no case study shows a date.
Work spans hospitality, insurance, pharma, automotive/retail, aviation/defence and publishing with no single declared vertical, and the advertised AI Experience Design rests on one example (the Allianz AI insight portal).
Best for buyers wanting a senior-led research-and-design redesign of a transactional product who will ask for the metrics behind each headline claim.
Key strengths
- Process is shown end to end across multiple studies—stakeholder workshops, UX audits, journey mapping, atomic-design systems and remote user testing on low-fidelity prototypes appear in the Best Western and Barnett Waddingham cases.
- Two engagements report defined timelines (14 and 12 weeks) and conversion/revenue outcomes, giving you a concrete benchmark for scope and pace.
- Verifiable legitimacy: a registered UK entity (LM UXUI Ltd), Clutch "Top" recognitions for 2024, and attributed client testimonials from named blue-chip brands.
Good to know
- No case study carries a date and no team page lists named consultants or headcount—ask for recent (last 12-18 months) examples and confirm who would staff your project.
- Outcomes are inconsistent: request the measurement method behind the +32% revenue and ~90% win-rate figures, and ask what changed for the cases (Allianz, J&J) that show no metrics.
- AI Experience Design is marketed but evidenced by a single Allianz portal—if AI is central to your brief, ask for additional shipped examples before committing.
