Unfortunately nobody on here can post the name or names of the companies they work with on the side, since they'd benefit from doing so. I will post that I am a W-2er with the biz I own, own a 2nd traditional biz on the side, and own a well-known private franchise for a 3rd. Definitely keep your options open. Working a 9-5 was so last generation and those ahead of the curve have other business interests on the side.
