Based on 13 documented clients · verified Jul 2026
Our Take
IDEO publishes 15+ case studies spanning nearly 50 years, with standout projects for H&M (22% stock reduction, 34% sales increase via supply chain redesign), Teal Health (FDA-authorized at-home screening device tested with 220 participants), and Boom Supersonic (full-scale cabin prototyping leading to American Airlines order)—each showing documented research, prototyping, and measurable business outcomes.
At €200+/hr, IDEO operates at the top of the market, and the work justifies the positioning: this is organizational transformation and new venture design for Fortune 500 companies, not interface design for startups.
This is a partner for Fortune 500 transformation and new-venture creation—one that embeds human-centered design capability inside the organization, as it did with Ford's D-Ford hubs and Zalando's Berlin studio, rather than delivering interface work at startup budgets.
Key strengths
- Published case studies include specific business metrics—H&M saw 34% sales increase and 22% stock reduction; Teal Health achieved FDA authorization with 97% ease-of-use in a 220-person clinical study
- Nearly 50-year track record with C-suite client testimonials from Ford, Moderna, and Intercorp—signals a firm that operates at the executive level, not just the project level
- Work spans physical products (Boom cabin, Teal Wand, Fizik helmets), digital platforms (FEMSA/OXXO, Sephora), and organizational design (Ford, Moderna)—rare breadth backed by evidence in each category
Good to know
- At €200+/hr with no published maximum rate, request a detailed scope and fee structure early—IDEO's engagements are typically large-scale and may not suit projects under six figures
- London office is one of several global locations—confirm which team and office will lead your engagement, as case studies span US, Latin America, and European work
- Most published case studies focus on strategy and product creation rather than ongoing UX design or interface optimization—if your need is iterative digital product improvement, clarify whether IDEO's model fits
