Series C is a stage of funding for startups that have already proven their business model and are looking to scale further. At this point, companies typically seek larger investments to expand their operations, enter new markets, or develop new products. Investors in Series C rounds often include venture capital firms, private equity firms, and sometimes hedge funds. During a Series C round, companies may raise tens of millions to hundreds of millions of dollars. This funding helps them achieve significant growth and prepare for potential future events, such as an initial public offering (IPO) or acquisition by larger companies like Google or Amazon.
