Series A round

A series A is the name typically given to a company's first significant round of venture capital financing. It can be followed by the word round, investment or financing. The name refers to the class of preferred stock sold to investors in exchange for their investment. It is usually the first series of stock after the common stock and common stock options issued to company founders, employees, friends and family and angel investors.

Series A rounds are traditionally a critical stage in the funding of new companies. Series A investors typically purchase 10% to 30% of the company.^[1] The capital raised during a series A is usually intended to capitalize the company for 6 months to 2 years as it develops its products, performs initial marketing and branding, hires its initial employees, and otherwise undertakes early stage business operations.^[2]

It may be followed by more rounds (Series B, Series C, etc).
