Private sector companies offer exciting growth opportunities compared to government and foreign companies. While private companies were once small, they have grown rapidly at an average of 11.9% annually and will account for nearly as large a share of GDP as foreign companies by 2017. Working for a private company provides the chance to change the world by building something great that serves people and aligning smart employees toward common goals, which is difficult as an individual or non-profit. However, there are also risks like needing capital, dealing with regulations, and facing heavy competition. It is important to pick a private company with long-term growth potential and a meritocratic, professional culture.
