To build a successful brand that customers love, you must be able to articulate why your product should exist and be willing to share that story over and over, says Randy Goldberg, co-founder and chief brand officer of Bombas.

Founded in 2013, the high-end sock maker made a name for itself with a pledge to donate one pair of socks to a homeless shelter for every pair sold. The company has since added T-shirt lines and has donated more than 40 million clothing items. It's also made the Inc. 5000 list of America's fastest-growing companies each of the past three years, and is a two-time Best Workplaces honoree.

Goldberg and David Heath, Bombas's co-founder and CEO, spoke with managing editor Lindsay Blakely in an Inc. webinar, "Your Next Move: Build a Business People Love," on Thursday.
