Financing is the behavior and process of raising funds for enterprises. The general order is angel investment →A round (1 round) financing →B round (2 rounds) financing →C round (3 rounds) financing, etc.
Generally speaking, according to the cycle of enterprise growth:
Angel investment: there may be only one concept in the seed stage, and nothing has started, or it has just started to operate, and the product has not yet been released, or the product has not been sold on a large scale. Water at this time, the seeds will grow, and you are an angel.
Seeds will grow up, and there are still many risks in the process of growth, which need more care. So there is the name of venture capital, and after the A round is the B round.
If you like, you can also have wheels C, D, E, F and G. Of course, the names A, B, C, D and E are just common names. Or the first round, the second round, the third round.
