I agree with the above. Pursue your venture if it's an idea you believe in and if you're comfortable taking the risks necessary to make it happen. Don't do it just to bolster your application; that will be transparent.
As for the feasibility of it all, I can offer you my experience: I managed to study for the GMAT while working a full time (+) job and running my own business. And I got a 99th percentile score. So it can certainly be done.
Thanks for sharing your thoughts, skahuh!
Have you posted your debrief on this website? What was the basic strategy and sources you used?

Define low GMAT score. Additionally, which schools are you targeting?
The key is to have good leadership experience. For example, you start a business and you have to manage 20 people vs. starting a business and managing 1 person. In other words, will you get lots of leadership exposure?
I haven't yet taken the GMAT, as I have been both studying and working full time, but my university degree will be acquired in a week, so I will have more time to devote to GMAT and TOEFl. Low GMAT score for me would be 600 as I'm set to get above 700.
I'm pinning my hopes to be enrolled into HBS, LBS, Stanford or as the second best it would be Insead, IE and Hong Kong UST Business School.
I'm at the crossroads now trying to figure out how should I continue my journey called life

. I'm from Ukraine, a country that is ranked 152 among worlds most economically developed countries. The likelihood of getting into one of those schools are pretty much poor. Besides, few of my friends believe I should opt for this way Perhaps, for these reasons I ask somewhat weird questions.
I take the view that leadership is not only about managing people, it's about leading people. Organising a class of English and hosting it would be a good example of leadership, wouldn't it? No doubt that deciding whether your company should operate in Australia or Russia manifests leadership much more than my example.
Does it matter if you're managing 20 people working for somebody and 5 working for yourself? I think it does. The second is harder to achieve.
