Are there fees for making your shares tradable?

What are Funderbeams fees?

Initial selling fee applies when offering transferred shares for sale via the Funderbeam Marketplace. This fee will be debited from the sale price of the shares and will only apply to the initial shareholders.
If you decide to hold your shares until a successful exit (IPO, merger), Funderbeam will only charge a success fee (detailed in the relevant agreement).

Are there any other fees that may apply to the share transfer?

There may be third-party (e.g. bank) fees in order to transfer your shares to Funderbeam.
