A Series C Investor is an individual or firm that provides funding to a startup during its Series C round of financing. This stage typically occurs after the company has demonstrated significant growth and market traction, and the investment is used to scale the business further, enter new markets, or prepare for an initial public offering (IPO).

Series C Investors play a crucial role in helping startups expand rapidly. Their funding supports scaling operations, increasing market reach, and enhancing product development. This investment round often attracts larger institutional investors, signaling confidence in the startup's potential.
Startups use Series C funding to accelerate growth, such as hiring more staff, expanding into new geographic areas, or acquiring other companies. Series C Investors typically expect a lower risk compared to earlier rounds but look for strong returns as the company moves closer to profitability or an IPO.
Common Series C Investors include venture capital firms, private equity firms, hedge funds, and sometimes late-stage venture capitalists. These investors bring not only capital but also strategic guidance and industry connections to help the startup succeed.
