One of the many benefits of Inc.'s annual search for America's 500 fastest-growing privately held companies is that it generates leads that we can explore more deeply and write about in future issues. Such is the case with the story of Under Armour Performance Apparel--a seven-year-old business based in Baltimore and the subject of a new regular feature we are launching this month, entitled "How I Did It" (page 102). I first noticed the Under Armour brand in gyms and hockey locker rooms several years ago. I even bought a pair of Under Armour shorts. But Kevin Plank's company remained undiscovered by the business press until our research staff determined it was going to land in the No. 2 spot on our list. (We profiled the No. 1 company, American Biophysics, at length in this fall's Inc. 500 issue.) Plank played football at the University of Maryland but discovered that entrepreneurship was what really got his adrenaline flowing. Following graduation, he started Under Armour in his grandmother's home and built it into a company that amassed revenue of $50.7 million in 2002 and a five-year growth rate of 12,573%. This year, Plank expects revenue to surpass $110 million. The 31-year-old still has a long way to go before his company topples Nike, but he clearly has already done more than a few things right. That's why we asked him to share some of his secrets with our readers in our first "How I Did It"--a forum for company builders to pass along, in their own words, the wisdom they have acquired. Actionable advice will be a top priority in this monthly feature, but we also recognize that business success requires emotional savvy. Thus, "How I Did It" will also delve into the life experiences of business owners and examine the struggles they've had, the doubts they've overcome, and the relationships they've built. In the end, we hope you'll find this concise feature both useful and inspiring. Incidentally, applications for next year's 500 will be available at as of Dec. 1.ÊWho knows, perhaps "How I Did It" will one day showcase you and your company.
