EXAMPLE

To name the organization to which the founding member belongs, German usually uses the genitive or the preposition 'von' with the dative.

Gründungsmitglied vs Mitglied
member
'das Mitglied' and 'das Gründungsmitglied' are closely related, but they do not mean the same thing. 'Mitglied' is the general term for a person who belongs to a club, organization, or company. 'Gründungsmitglied' is a specific person who was already there when it was founded. The words can be confused because a founding member can also be a member. But many members only join later. If the time of founding is not relevant, you simply say 'Mitglied'.
Gründungsmitglied
Sofia ist Gründungsmitglied der kleinen Firma und kennt ihre Geschichte genau.
Sofia is a founding member of the small company and knows its history very well.
Mitglied
Am Morgen bezahlt er den Beitrag, weil er Mitglied im Wanderverein ist.
In the morning, he pays the fee because he is a member of the hiking club.
