This is a fee that companies are charged by Netcapital and is not applicable to investors.
Companies that raise on our site pay Netcapital a portal fee, which is typically around 4.9%. This fee is a percentage of the amount raised upon the successful raising of capital through our platform and is a cost on the issuer.
The portal fee is charged to the company, not to the investors. For example, if you invest $500 worth of shares in a company, you will own $500 worth of shares at the time of the successful closing.
