Bark & Co.

Bark & Co.'s first product, BarkBox, provides a monthly delivery of innovative treats and toys that pups can wolf down and tear apart to their hearts' content. The growing number of consumers eager to pamper their pooches has fueled some impressive growth: The five-year-old company has shipped more than 20 million products, and just raised a $60 million Series C round of capital. While BarkBox accounts for approximately 75 percent of revenue, the company has branched out into several other business models. BarkPost is filled with dog news and videos; BarkShop is an e-commerce site where customers can buy all manner of dog paraphernalia without committing to a subscription; and BarkLive sponsors dog-centric live events such as Open Bark Night, where waggish stand-up comedians share drinks and dog stories.
