Personally I get a huge kick out of making massive improvements to a small business's tech and infrastructure. The lack of bureaucracy is a freedom that is often taken for granted. If you have the vision and drive, you can improve the business's processes and product offerings by leaps and bounds...something I would argue is not readily available at a big company. Smaller companies are also much more willing and able to negotiate with you to help balance your life. A 4-day work week for example.
Again speaking anecdotally, I don't need that much money. I certainly don't need FAANG-level compensation. If I'm going to work somewhere, it's going to be because I want to be with those people, working on those problems, and having a big impact. Not because of the fat paycheck.
