The difference between private and public companies is that private companies do not trade their shares and stocks to the public, so they can maintain all of their finances internally without having to submit financial reporting for their investors to look at. They also do not have to deal with Securities and Exchange Commission, which means less work for them in terms of reporting. An advantage of Private companies is that since they do not have to pay out investors they can decide how much of that money they can keep and how much they can give away to employees in terms of profits. However, Private companies can not rely on outside investors for financial support and must come up with the money to work and start up internally. Public companies have to issue their stocks for trade to the public, which requires more work in terms of filling financial reports and reporting to the SEC. Public companies are able to gain more money from outside investors to work with, which can give them more room to grow and expand, but more stress of keeping more investors happy. An example of a private company is DELL, which is a massive technology company that pulls in billions of dollars of revenue a year, and have been expanding and releasing new products every year as they keep up with the changing world. A publicly traded company would be EXXON Mobile, which provides oil to the United States, owning gas stations all over the country, and owning oil rigs across the world, netting a total revenue in the billions.
