为什么要众筹？这个问题涉及到许多方面，例如创业、创新、个人需求等。下面我们来一一解析。

首先，众筹可以帮助创业者筹集资金。在创业的初期，许多创业者缺乏资金支持，因此他们可以通过众筹平台向公众募集资金，从而获得创业所需的资金支持。此外，众筹还可以帮助创业者扩大社交网络和增加人脉资源，从而更好地推广自己的品牌和产品。英文翻译为: Why do we need crowdfunding? This question involves many aspects, such as entrepreneurship, innovation, personal needs, etc. Let's analyze them one by one.

Firstly, crowdfunding can help entrepreneurs raise funds. In the early stage of entrepreneurship, many entrepreneurs lack funding support, so they can raise funds through crowdfunding platforms to public investors, thereby obtaining the necessary funding support for their businesses. Additionally, crowdfunding can help entrepreneurs expand their social networks and increase their connections, thereby better promoting their brands and products.

其次，众筹可以帮助创新者实现创新梦想。有时候，一些创新项目可能需要大量的资金支持，而传统金融机构可能无法提供足够的资金支持。因此，这些项目可以通过众筹平台向公众募集资金，从而获得更多的资金支持，实现自己的创新梦想。英文翻译为: Secondly, crowdfunding can help innovators realize their innovation dreams. Sometimes, some innovative projects may require significant capital support, but traditional financial institutions may not be able to provide enough funding. Therefore, these projects can raise funds through crowdfunding platforms to the public and gain more financial support to realize their innovation dreams.
