Nearly every large company has one thing in common � at one time it was no more than an idea in one person's head. Cities and nations are built on the backs of enterprising souls eager to own a business of their own. Baltimore has its fair share of big name entrepreneurs such as the late Reginald F. Lewis and Under Armour's Kevin Plank, but the city also has a wealth of small business owners living their dream as bakers, biotech developers, booksellers, filmmakers, real estate developers, restaurateurs, and more.
