I work for a company that designs custom lighting hardware. Projects are based on customer needs but sometimes project scopes change and a design I think of is no longer needed. I would like to start my own company and start designing and selling my own hardware but I don't want there to be conflict between my own future business and my current place of work. I figured that I could continue to build things outside of work and then the company I work for could buy items from my company since we already purchase A LOT of bought out items (I would create and sell items that do not exist on the market). How does kind of thing work? Do I create an LLC?
