What does being 'rolled up' mean?
Edited
Being 'rolled up' simply means that your Angel Investment is going to be pooled in one trust entity (“Treuhandgesellschaft”) along with the other Angel Investors in order to facilitate the investment process for you and the founder.
This results in:
No additional costs
No economic changes to your investment
Removal of the notarization requirement for the PoAs for most investors.
