A Series C Backer is an investor who provides funding to a startup during its Series C financing round. This round typically happens after the company has proven its business model and is looking to scale operations, enter new markets, or develop new products. Series C Backers often include venture capital firms, private equity investors, hedge funds, and sometimes large corporations.

Series C Backers invest in startups that have moved beyond early-stage funding rounds like Series A and B. At this point, the startup usually has a solid customer base, steady revenue, and clear growth potential. The funding from Series C Backers helps the company expand rapidly, whether by increasing production capacity, entering international markets, or acquiring smaller companies.
Investors in Series C rounds are often more diverse than in earlier rounds. They can include late-stage venture capitalists, private equity firms, hedge funds, and strategic corporate investors. These backers are looking for companies with proven success and lower risk compared to earlier-stage startups.
Startups seek Series C Backers to raise significant capital needed for large-scale growth initiatives. This funding round is crucial for preparing the company for an initial public offering (IPO) or acquisition. The involvement of Series C Backers also signals to the market that the startup is a strong contender in its industry, which can attract further investment and partnerships.
