Reaktor
Helsinki, Finland
About
Global consultancy with Nasdaq fintech and Varian medical systems experience.
Who They Work With
Enterprises scaling a customer-facing digital product who want design, engineering and data on one team—like Cathay Pacific or adidas.
Based on 18 documented clients · verified Jul 2026
Our Take
Reaktor publishes 60-plus freely visible case studies spanning aviation, health, finance, gaming, industrial, public sector and retail, and the design work holds up alongside the engineering: the Cathay Pacific in-flight system case cites 1,000-plus iterative passenger tests, accessibility-led design across 14 screen types, and Red Dot, iF and German Design Award wins, while the adidas ecommerce case documents research, design sprints and prototyping next to outcomes like 60% faster page loading and a revenue goal of 4 billion euros reached by 2020.
The caveat is breadth over depth on method: most case studies lead with awards, traffic volumes and engineering performance figures rather than usability metrics or before-and-after research findings, and the firm positions itself as a strategy-design-engineering-AI consultancy rather than a standalone UX practice, so design is one discipline inside larger transformation programs.
The design genuinely holds up alongside the engineering—Cathay Pacific's award-winning in-flight system ran 1,000+ passenger tests—but most cases lead with awards and traffic figures over usability metrics; confirm how much of your team is dedicated UX versus engineering.
Key strengths
- 60-plus ungated case studies across aviation, health, finance, public sector and retail, with named enterprise clients including Cathay Pacific, adidas, HBO, Nasdaq, Varian and ABB.
- Documented design-research practice on flagship work (1,000-plus passenger tests and accessibility design across 14 screen types on Cathay Pacific), plus multiple international design awards.
- 600-plus staff across 8 offices in 4 countries (Helsinki, Turku, Tampere, Seinajoki, Amsterdam, Lisbon, New York, Tokyo), with 30% of employees over 13 years tenure for continuity on long programs.
Good to know
- Most published cases emphasize awards, traffic volumes and engineering performance over usability research findings; ask for the research artifacts, testing methods and before-and-after UX metrics behind a comparable project.
- Reaktor positions as a full-lifecycle strategy-design-engineering-AI consultancy, so confirm how much of the proposed team is dedicated UX/design versus engineering and strategy before committing.
- No public rates are listed and engagements appear consultancy-scale; request a staffing plan and budget range early to confirm fit for a design-led rather than transformation-scale scope.
