Startups fundraise in 'rounds' as they prove out their business and scale

When startups take on outside funding, those investments are divided into different "rounds." These rounds are catered to different stages in a startup's life cycle—a startup often needs different types of investors and amounts of funding at different stages of the business. For instance, a pre-seed investment round can include investments ranging from about $25K to $500K, whereas a Series D investment can be hundreds of millions of dollars.
