- Pre-seed and Seed rounds (also called "friends and family" rounds) are used to launch an enterprise
- Angel rounds are early investments by angel investors.
- Venture rounds are large investments led by venture capital firms. These are often denoted by the series of stock sold, e.g. "A round," "B round" and so on. The name of the round suggests the stage in the company's growth.
