Board, and to finance his purchase, Arizmendiarrieta negotiated interest-free loans with several companies in exchange for them taking advantage of the cooperative as their own commissary. The San Jose Consumer Cooperative also served as a work balance by employing mostly women, since Arizmendiarrieta devoted special attention to promoting women. To do this, he expanded a teaching section in the Professional School, focused on the 400 single female workers who existed in Mondragon. Over the years, more consumer cooperatives were created, and in September 1969, as a result of the merger of the San Jose Cooperative, with several cooperatives based in the towns of Arechavaleta, Amorebieta, Marquina, Guernica, Éibar, Ermua, Matiena and Recaldeberri (Bilbo), the new company Eroski Group was created.

Likewise, in the summer they obtained a license to manufacture selenium plates under the patent of a German company. Arizmendiarrieta relied on talented young people he knew from the School, under the premise that "to create cooperatives you have to train cooperative members." On the other hand, the new businesses were promoted with a double logic: that they did not previously exist in the Alto Deba Valley, to avoid entering into competition with them, and that they were linked to their professional knowledge acquired in the Locksmith Union and the Professional school. Thus, Usatorre and Larrañaga took charge of the electrical appliances, Ormaetxea of the foundry, and Gorroñogoitia of the electronics. In August they took advantage
