There is a subtle but important difference between understanding how business function and going to business school, the former is more important when starting a startup. If you want to learn more about the business aspects, move to a different role in your current company in the business side, like Sales, Sales engineering, etc. The opportunity cost in time and money is another concern. You can take the 2 years of time, and probably less than 1/2 the amount you would spend on B school to startup your startup, which, would be a better learning opportunity.
