There are several aspects here that need to consider. First, should check the legal aspect. Can you have a company in paralel? Sound like its related for what your company does then it can be an issue. The focus aspect - do you believe you can run a company aside? Its very important to be focused especialy in startups. What is your added value? If its only the idea, and from there anyone with some general knowledge on the domain can continue then it will be much complicated for you and the main option I see with big value for you is opening a new company and you act as investor and a little more. But if you have a lot of value and will need your expertiese and consultation, in that case you will be able to start a company with cofounders that will need you and you will need them and for the other options, you will have levarage inside your company to get more shares (in the first case they can get your odea and apply it but in the second case they realy need you). For last its more about your personality, some are fit more to be founders and some are more to work in companies as employees, they are both ok but depend on your personal preferences. I hope it helped.

I like the second one as in the video. Why did you develop it? What is the pain point/need?
