Yes, it's possible. There are tons of rich people who are not famous. The owner of the company I work for is a billionaire many times over. It's a private company, he's not famous. Perhaps in his industry. But outside of that, 99.99% of people on HN will pass him on the street and not recognize him. So you are worried about the wrong stuff, go start a business. The hard thing is making it successful. With that said, some businesses draw attention and folks might want to know the owners. However, I bet many people on here can't tell us the name/founder or CEO of TikTok, Onlyfans, Lucid Motors. You have to court the press/fame to become famous outside of your bubble.
