Groupon has raised $950M in total funding, with its largest round being the $950M Series D in January 2011, backed by Andreessen Horowitz and Kleiner Perkins. Founded in 2007 in Chicago, Groupon rapidly expanded into a global deals marketplace offering discounts on services, products, and travel. Its funding accelerated international expansion, merchant partnerships, mobile app growth, and acquisitions. As the company matured, Groupon shifted toward marketplace efficiency, lean operations, and a more curated merchant ecosystem. With nearly 969 employees, Groupon continues to refine its platform for local commerce.
