Series B Round Law and Legal Definition

Series B Round is the second round of financing by venture capitalists. This round comes after the Series A round. Receiving a Series B round denotes that professional investors are interested in providing finance to the company after the Series A round.

When a company raises venture capital by selling its preferred stock, the shares of preferred stock sold in a given financing round are defined with a letter. "Series A" shares are shares sold in the first financing round. Subsequent rounds are called "B", "C", "D", and so on. Shares in a particular series have similar rights.
