Co-Founder and President

CustomInk began a few years ago as a small virtual store that enabled customers to design and order custom-made merchandise including t-shirts, sweatshirts, caps and mugs. As a small startup business, founded in March 2000 by Harvard University graduates Marc Katz and Dave Christensen, CustomInk initially focused on serving college student groups such as sports teams, fraternities and sororities. Schools provide their trademarked logos, which are then made available on CustomInk's Web interface for use in custom designs by school groups, alumni associations, and team fans. The business currently is also rapidly expanding into the small business, corporate and recreational sports markets.

CustomInk's patent-pending design interface, as well as an online library of more than 15,000 pieces of artwork, hundreds of fonts, text tools, the capability to accept uploaded images, allows customers to design and order online customized apparel, drink ware and novelties for their businesses, teams, groups and events.

CustomInk is privately funded and headquartered in the northern Virginia high-tech corridor.
