Crowdfunding is an online business-building method that involves raising money from a large number of people, typically through the internet. It is a way for entrepreneurs to raise capital for their projects or businesses without having to go through traditional financing methods such as banks or venture capitalists. Crowdfunding can be used to fund a variety of projects, from start-ups to charities and even personal causes. It is becoming increasingly popular as a way to finance new ideas and projects, as it allows people to invest in something they believe in and have a direct impact on its success.
