Der Bedarf an Unternehmensnachfolgen ist groß und wächst stetig weiter. Über 75% aller deutschen KMU, die eine Nachfolge innerhalb der nächsten Jahre benötigen, haben noch keine Lösung gefunden und müssen sofort handeln, um ihren Betrieb zu sichern. EterniTeam übernimmt deutsche KMU, etabliert einen qualifizierten und langfristigen Nachfolger und beteiligt diesen und alle Mitarbeiter mit jedem Jahr mehr am Unternehmen und dessen Gewinn. Der scheidende Geschäftsführer geht so ohne Verzicht auf Erlös und mit der Gewissheit in den Ruhestand, dass sein erfolgreiches Unternehmen auch zukünftig in guten Händen ist und nie wieder verkauft werden muss. Unser Ziel ist es, dem ausscheidenden Unternehmer eines traditionsreichen Unternehmens ein Denkmal für die Ewigkeit zu setzen.
