I think that the common thread for many businesses that have bootstrapped to high-profit profitability in very short order, with little startup capital is enterprise software that the founding team has either A) created and has a very good unique value proposition or B) services very well and in either case, has dedicated sales staff. Most other businesses take a fair amount of money for either equipment or marketing. Logik talks instead about how it's first sale was around $45,000.
