I have no desire for fame and I don't like "putting my name out there".
But I still want to run a business. My strategy would be to eventually get a partner who could eventually "be the face of the business" but I'd still have to build it up.
Is it possible to do any remain anonymous - maybe I use pseudonym?
At a certain point I had come to a realization that things operate a certain way for 99% of people and companies and being contrarian doesn't help. If you want to win you need to play their game and that may mean having a public presence and playing on their playing field (that field may be LinkedIn, Github and other common fields).
I will say you don't have to become an influencer asshat which is what I want to avoid at all costs. You don't need to be "famous" and build a following of any kind. I focus my time on networking and building trust within my domain.
