Did you miss this bit above?:

I did miss it, thank you

You can still apply multiple times after getting rejected. There’s plenty of stories of companies/founders that only got into YC after several rejections

To be honest, if I were in their situation I wouldn’t apply again, but it could be a good move regardless

I'm not sure what YC's stance is on investing in established businesses, but in the VC world as a rule it is 'not done' to invest in multiple competitors active in the same field. That path is rife with conflicts of interest.

You are right. Not sure about their official policy, but I know of multiple instances of where they’ve invested on competitors of their own companies

Sometimes this happens without them even knowing, because they put money into a company very early on, then the company pivots and starts competing with another YC company

All of the VCs I'm involved with would definitely have a problem with that.

I'm not sure at this point I want to apply and talk about our company's vision and mission.

Obviously... that would make a whole pile of assumptions and my put you in an even more difficult spot.
