With the financial backing of several Jewish investors, including one of the owners, Abraham Bankier, Schindler signed an informal lease agreement on the factory on 13 November 1939 and formalized the arrangement on 15 January 1940. He renamed it Deutsche Emailwarenfabrik (German Enamelware Factory) or DEF, and it soon became known by the nickname "Emalia". He initially acquired a staff of seven Jewish workers (including Abraham Bankier, who helped him manage the company) and 250 non-Jewish Poles.

On 18 November 1939, during the early months of the Nazi occupation of Poland, Oskar Schindler was first introduced to Stern, who was then working as an accountant for Schindler's fellow Abwehr agent Josef "Sepp" Aue, who had taken over Stern's formerly Jewish-owned place of employment as a Treuhander (trustee). Schindler showed Stern the balance sheet of a company he was thinking of acquiring, an enamelware manufacturer called Rekord Ltd owned by a consortium of Jewish businessmen (including Abraham Bankier) that had filed for bankruptcy earlier that year. Stern advised him that rather than running the company as a trusteeship under the auspices of the Haupttreuhandstelle Ost (Main Trustee Office for the East), he should buy or lease the business directly, as that would give him more freedom from the dictates of the Nazis, including the freedom to hire more Jews.
