The advantages of the parallel entrepreneurship model include being able to use common platforms and resources, experience and lessons learned being readily shared, and the ability to experiment more as your entrepreneurial portfolio is diversified.

The disadvantages potentially include lack of executive attention if the model is not well constructed, and it being harder to find outstanding individual startup leaders, some of whom may be more inclined to come up with their own ideas even if their chances of success are lower.
