Online crowdfunding is a method of raising money through the internet, where individuals or organizations can collect small contributions from a large number of people. This approach is often used to fund projects, startups, or charitable causes. Platforms like Kickstarter and GoFundMe allow creators to present their ideas and set funding goals, making it easy for supporters to contribute. Crowdfunding campaigns typically offer rewards or incentives to backers, such as early access to products or exclusive merchandise. This model not only helps fund initiatives but also builds a community of supporters who are invested in the project's success.
