No observed cheques. Organisations of this type rarely announce deals, so this says nothing about their activity.
From their own site: “Als Multi-Family Office investieren wir unser eigenes Kapital und das von weiteren, nahestehenden Unternehmerfamilien (keine komplexen institutionellen Strukturen).”
An announcement gives the size of the round, not the size of this investor's cheque. The only rounds that imply a cheque are those where they were the sole named investor.
