The firm that brought human-centered design into mainstream business practice. With six offices across three continents — San Francisco, New York, Chicago, London, Munich, Tokyo — IDEO operates as a genuinely global practice, with the ability to deliver multi-market engagements while retaining cultural fluency in each region. Their ability to operate upstream of a brief — mapping problem spaces before proposing solutions — remains unmatched. When an organization does not yet know what it should be building, IDEO is where you go before you go anywhere else.
