IDEO vs Nomensa: overview
IDEO
When people say "human-centered design," they're usually echoing language IDEO helped establish after its 1991 formation — a merger of David Kelley Design, Moggridge Associates, ID Two, and Matrix Product Design. Based in the San Francisco Bay Area with close to two dozen studios worldwide, the firm's case-study list includes the original Apple Mouse alongside long relationships with Procter & Gamble, PepsiCo, and major US health systems. Access to that legacy isn't cheap: industry roundups put typical engagement minimums near $300K (per industry roundups; independently unverifiable).
Nomensa
Simon Norris, Sally Lincoln, and Alastair Campbell founded Nomensa in 2001 around a specific combination: psychology, user-centered design, and accessibility. Now running from Bristol, London, and Amsterdam with 100+ people, the company calls itself one of Europe's largest specialist UX agencies, serving banking, e-commerce, education, entertainment, government, and healthcare clients. Accessibility isn't an add-on service here — auditing, testing, training, and consultancy sit alongside standard UX design work.
