KOOS Agency
Amsterdam, Netherlands
About
Strategic design agency combining service design, UX, and AI with accessibility as a core UX/UI offering.
Who They Work With
Enterprise and public-sector orgs—Careem, VGZ, Dutch police—needing service design and CX transformation at scale.
Based on 7 documented clients · verified Jul 2026
Our Take
KOOS publishes 10+ case studies across public sector, healthcare, big tech, and mobility—the Careem Super App project served 50 million users, VGZ health insurer saw a 13% increase in customer satisfaction, and the Dutch police project involved VR training for crime scene management. The work demonstrates strategic design at scale, with AI design emerging as a distinct capability alongside service design and UX/UI.
Accessibility is listed under UX/UI services rather than as a standalone offering. The agency's strength is large-scale service design and digital transformation, not dedicated accessibility auditing.
The strength is large, multi-year service-design and CX-transformation programmes—Careem, Digicel, NS, VGZ—often building the client's internal design capability; a newer AI-design practice is emerging, and accessibility sits inside UX rather than as a standalone audit.
Key strengths
- Published outcome metrics: 13% customer satisfaction increase (VGZ), Super App design for 50M users (Careem), telecom redesign across 25 markets (Digicel)
- Deep industry expertise across public sector, healthcare, mobility, finance, and energy with named enterprise clients
- AI design capability alongside traditional service design and UX—relevant if your accessibility work intersects with AI-powered products
Good to know
- Accessibility is a sub-capability within UX/UI, not a primary service—if you need a dedicated WCAG audit, confirm they have specialist accessibility auditors on staff
- Enterprise-scale agency (50-99 team)—may not be cost-effective for a standalone accessibility audit without a broader design engagement
- No published rates—request pricing early; expect enterprise-level pricing given the client roster
