Im really surprised how dumb (too harsh), uninformed, most people are when it comes to business. I highly suggest many of you enrol in an introductory business class at your local college, or surf investopedia for the day.
Co-founders of companies do start off with 100% ownership, however their shares diminish as the venture goes into the rapid growth stage, where cash infusions are critical. Zuckerberg obviously at one point owned the major of FB, but once they got to the rapid growth stage, they traded equity stakes for cash injections to goldman sachs and other high profile investors. Banks won't loan money to risky ventures, especially tech, so, giving up ownership to continue to grow the business. Would you rather have 80% of something worth $1,000,000, or 30% of something worth $10,000,000?
ownership has nothing to do with voting, as the corporate structure of a firm can be created with different share classes. E.g. Frank Stronach, the founder of Magna International, had shares in which each preferred class shared, gave him 10 votes. Therefore, his voting power allowed him to sell common class shares to the public, which still controlling the company.
Some people went as far as to mention Michael Dell and bill Gates ownerships in their respective companies? How do you think they became billionaires? Clearly by selling shares over the decades in which they've been in operations. I can go on, but its pointless
