Each company on Netcapital sets a minimum and maximum target amount to raise.
When an offering starts, the issuer, or the company raising capital, sets a minimum and maximum target for its raise. If the offering surpasses the minimum raise requirement ($10,000, in most cases), then the company will be considered to have finished its raise successfully. If an issuer does not reach their minimum target, the offering will close unsuccessfully and invested funds will be returned to each investor.
In addition to a minimum target, issuers also have to set a maximum target for their raises. If the maximum target is reached before the offering closes, the offering is sold out and the issuer will not be able to accept any more investments.
