I'll share a bit. I'm a solo, international founder. I applied with a barely usable, very limited prototype, of a technically challenging project (involving A.I and machine learning). My video was viewed twice, and my demo was viewed, but no other action was taken within it. I was rejected.
I expected that, given that my prototype was pretty bad, and I have a lot going against me. It definitely lit a fire under me just to apply though - and the questions that the application asks, are things you really need to think about. I definitely don't regret applying. And the fact that my demo & video were viewed - makes me think that perhaps my idea is somewhat promising.
I was a "solo founder" type for awhile. If you're an engineer I think you can have your pick of co-founders.
My suggestion, after working on and for startups for a couple decades is that you should be the CEO, find business people to be co-founders, and hire a VP of engineering, or CTO.
It's almost a cliche that there are business guys "starting companies" who "just need an engineer"... but I think the best chances for success - on a high tech startup - are for the engineer to be the CEO, and eventually bring on a CTO.
One advantage of this- the CEO is focused on product while the business guys (COO, CMO, whatever) are out doing the legwork for raising money. I've seen too many companies flounder because the CEO was focused on raising money.
You can learn business, they can't learn engineering. (well, they can, but not to your level in the time available.)
You do need a co-founder though to build a startup. The value of having 1 person to bounce ideas off is incredible versus just yourself. The value of the second co-founder for bouncing ideas off is 50% less than for the first one, that's why one co-founder is optimal.

I plan on improving my product a lot and re-applying next batch. https://www.youtube.com/watch?v=12DAjoONx9E&t=35s
