This article discusses how many entrepreneurs create multiple ventures, and thereby apparently lengthen the duration of their entrepreneurial careers. A new concept, called the Corridor Principle, is proposed as a possible explanation of the multiple venture phenomenon. The Corridor Principle states that the mere act of starting a venture enables entrepreneurs to see other venture opportunities they could neither see nor take advantage of until they had started their initial venture. The Corridor Principle presents an alternative model to the linear single venture career model, embodied by such celebrity entrepreneurs as Ray Kroc of MacDonald' s and Kenneth Olsen of Digital Equipment Corp. Six hypotheses test expectations about the timing and duration of entrepreneurial careers, as well as the relationship between entrepreneurial career length and the creation of multiple ventures. The findings strongly support: • the position that entrepreneurship is a dynamic, multi-venture process for a great many entrepreneurs the rule, rather than the exception. • the existence of a positive correlation between finding at least a second venture and realizing a longer entrepreneurial career. Though there are a variety of explanations for this, and the patterns include both sequential and overlapping ventures, the net effect of creating multiple ventures appears to produce a longer entrepreneurial career. • the position that significant numbers of entrepreneurs create their second venture very early in their entrepreneurial careers especially when contrasted to the group of ex-entrepreneurs, who create multiple ventures (if at all) at a slower rate and later in their careers. Overall, these observations reinforce the notion of the Corridor Principle. Though who can and cannot take advantage of the Corridor Principle is not entirely revealed by the data, some indication exists that an entrepreneurs ability to use Corridor Principle strategy to prolong his or her career is related both to age at startup, and to conscious anticipation and preparation for an entrepreneurial career. The main implications for entrepreneurship practitioners, advisors, researchers, teachers and students are these: Whether studying the entrepreneurial process or planning to start an entrepreneurial career, a long-term view should be taken, one that includes the likely possibility of multiple ventures. The minimum economic returns of earlier ventures can be lower than previously thought if these ventures provide entry to subsequent ventures that possess higher (more acceptable) returns to the entrepreneur. The evidence thus far available indicates that the creation of subsequent ventures occurs relatively quickly when corridors of opportunity become visible and attainable after earlier ventures are established. The likelihood of career failure, as opposed to venture failure, may be lowered if one selects earlier ventures based on their potential to reveal follow-on-venture opportunities that the entrepreneur can investigate and possibly pursue.
