Usage tips

The word is made up of the prefix 'Mit-' and the noun 'Gründer' (founder). The prefix 'Mit-' means 'together' or 'jointly', so a 'Mitgründer' (co-founder) is someone who founds something together with others.
EXAMPLE
Sie ist Mitgründerin der Initiative für saubere Parks.
She is a co-founder of the initiative for clean parks.
Word family
The word belongs to the family of the verb 'gründen' (to found). A 'Gründer' (founder) is the person who founds something. A 'Mitgründer' (co-founder) is one of several people who found something together.
EXAMPLE
Die Gründer trafen sich wöchentlich, um die nächsten Schritte zu planen.

Mitgründer vs Gründer
founder
'der Gründer' and 'der Mitgründer' both describe a person who starts something new, for example a company, an organization, or a project. 'der Gründer' can stand alone or generally refer to a person who founded something. 'der Mitgründer' emphasizes that this person was not alone, but founded something together with others. The words can be confused because a co-founder is also a founder. But if you want to show that several people were involved, 'Mitgründer' is more precise.
Mitgründer
Beim Termin erklärt der Mitgründer, warum das Projekt von Anfang an ein Team gebraucht hat.
At the appointment, the co-founder explains why the project needed a team from the beginning.
Gründer
Der Gründer der Firma spricht heute in der Bibliothek mit einer Kollegin über neue Pläne.
