[1] Mok founded several design-related businesses — Studio Archetype (acquired by Sapient), CMCD and NetObjects, Inc.
In 1997, Mok recruited George Chen in a photoshoot for an early collection of stock photography made for graphic designers distributed on CD-ROM, whose likeness was used in many high-profile print and billboard advertising campaigns, inadvertently creating an unofficial mascot for the dot-com era, nicknamed "The Internet Guy".
Mok also served as the national president of AIGA and was the creative director at Apple Inc. in the early 1980s.
Currently, he leads a new subscription-based royalty-free stock image business and consults on a variety of product development projects.
Mok authored an influential early information architecture manual, Designing Business (Adobe Press, June 1996).
