Kevin Lang, 30

Kevin Lang’s path to starting and growing a multimillion-dollar business is rather easy to explain. He started with a simple business concept, in capitalizing on a customer need. He followed that with a straightforward product, in personalizing tumblers, water bottles, mugs and other drinkware with laser-engraving machines.

“We saw the idea (of laser engraving) was getting really popular,” Lang says. “We wanted to find something on the cheaper end, but could still keep beverages cold or hot for extended periods of time.”
