Sharing business/pitch ideas in the application

I have few ideas for potential business, I never got to do anything with it (I don’t know any sponsors/investors who would be interested in) but I made formal presentation and pitch notes etc.
Is there a way to include some of that in my application? Would it be an acceptable supplementary material, if I for instance, recorded a video of myself presenting the idea or attach a simple PDF outlining the idea?

Admissions folks don’t really want to crawl through or read or watch the actual details of your activities, unless they say they want or allow specific types of supplements. I am not sure how you could even list it, unless you’ve found a way to at least pitch it somewhere. It is aspirational, not an actual accomplishment at this point. “I have a great idea” isn’t really helpful in admissions. “I have a great idea, and have accomplished this with it” is what is helpful.

@intparent But they also acknowledge the fact that there isn’t that much a HS student can do, and not everyone has the same level of opportunities, wouldn’t they?

There are HS students who have done something with it.

@intparent But again not everyone has same background and resources to do what they would have done. Isn’t the whole point of application getting to know the applicant with the context of their background?

Bottom line is the answer is a big no. You should absolutely not include a pitch for a business idea that never took off. You application should focus on things you have actually accomplished, not ideas you thought about.

This is the second time you asked about including more than the application asks for (you asked about putting in an entire second essay in another post). Any of this will all cause more harm to you application than anything else. Keep in mind that admissions officers are swamped – they typically spend about ten minutes on an application – they are not looking for extraneous things to read, watch etc. Don’t muddle your application up with extra stuff. Focus on what the application asks for – nothing more and nothing less.

There is a saying often used on CC – The thicker the file the thicker the applicant. Don’t be that person.

@happy1 If shorter applications are better, then is it better not to do optional supplemental essays? does it still work the same logic there?

I feel like there might be a difference between extra things they asked for (or have an established system to handle) and extra things they didn’t ask for.

No, it is not the same logic at all. Supplemental essays are a completely different story because the college offers them to applicants as a way to get more information. That is very different from providing extraneous material that has not been requested. I hope you can understand the difference. You should definitely do all supplemental essays, even the optional ones.
