Design + Know-How was established by Martine Trélaün in San Francisco during the early years of the second Gold Rush. After love affairs with Los Angeles, Seattle and yes, New Haven (a short-lived dalliance,) the studio now has two bases: Paris and New York.

Working in collaboration with a crack team of talented people, Design + Know-How dives into all sorts of projects: corporate identity and branding, illustration and photography, book design, web and interaction design; curating, writing, editing and translating; and pretty much anything that sounds either fun or slightly daunting.

No matter the size or scope of the assignment, we are committed to dreaming up interesting and arresting solutions for big fish as well as small fry. We strive to bring intelligence and creativity to every project, and pride ourselves on building enduring relationships with our clients.

Design + Know-How has won awards from the AIGA, the American Center for Design and the Type Directors Club, and has been featured online and in print publications such as the New York Times, The Type Directors Club Annual, Jalouse and Elle magazines. Martine is the 2008 recipient, along with Terence Arjo, of a grant from the Foundation for Living Arts in America for their project, Vanishing Soundscapes.
