These days, competition is fierce. It's no longer possible just to make a product and hope that it sells; products must be designed with end users in mind. Lextant Corporation provides design research for its business customers, including PepsiCo, Procter & Gamble, Motorola, Goodyear, Whirlpool, Microsoft, and Hard Rock Café. Its name comes from the word lexicon meaning a "vocabulary or language"-in this case, a language of consumers. The privately held Columbus, Ohio-based company strives to translate this language into actionable insights, equipping its clients to design for the motivations, behaviors, and desires of their customers.
