Almost everything is possible you manage to get the other shareholders to agree. That might happen when some early investors sometimes
want the founder to have more control especially before going public.
The theory is that you'd rather have a founder you invested on in the first place steering the company than let your generic wallstreet shareholder without a vision(tm) take over a unicorn still full of promise.
Sometimes the bet pays off, very very well. Take for example Musk. You can say whatever about him, but it's extremely clear he has a vision, and does pretty much anything to get there. I'm not sure tesla or spacex would've survived 2018 with someone else at the helm or if a shareholder revolt happened. Just by that metric he is already worth dozens of billions to the rest of the shareholders.
Zuck is also a good example of investors trading off votes for a more wall st. independant, steadier long term eadership.
Now keep in mind those are exceptions. Having supervoting shares orbmultiple classes of shareholders is very often not a good thing and usually leads to less value being generated.
Accountability to shareholders is usually good and very important to ensure sane corporate governance. Which is why CEOs and founders absolutely love having ever less powerful shareholders and we end up in situations like now where even the crappiest IPO has absurdly overgeared supervoting classes. Who doesn't want to buy in a deeply in debt, cash burning ipo with very questionable growth who's founder has a perpetual 80% of the votes?
