Skift Cheat Sheet:
We define a startup as a company formed to test and build a repeatable and scalable business model. Few companies meet that definition. The rare ones that do often attract venture capital. Their funding rounds come in waves.

Seed capital is money used to start a business, often led by angel investors and friends or family.

Series A financing is typically drawn from venture capitalists. The round aims to help a startup’s founders make sure that their product is something that customers truly want to buy.

Series B financing is mainly about venture capitalist firms helping a company grow faster, or scale up. These fundraising rounds can assist with recruiting skilled workers and developing cost-effective marketing.

Series C financing is ordinarily about helping a company expand, such as through acquisitions. In addition to VCs, hedge funds, investment banks, and private equity firms often participate.

Series D, E and beyond These mainly mature businesses and the funding round may help a company prepare to go public or be acquired. A variety of types of private investors might participate.
