With his early search for an answer to the industrial question, “What’s happening in the world?” the founder of Yıldız Holding, Sabri Ülker, both facilitated and accelerated the global economic integration of Yıldız Holding and its group of companies. During the 1960's, when it was nearly impossible to monitor developments in the biscuit and chocolate industry on a world scale, Sabri Ülker's search for a way to "take a step outside" was a key element in the group's adoption of an earlier than expected world vision.

In 1968, experts from the International Executive Service Corps (IESC) were invited to Ülker. The IESC had been established in the 1950’s to provide technical support to developing countries. Ülker benefitted greatly from the knowledge that these foreign experts brought to the company. The company that once requested experts from the IESC, has developed into the competitive, global giant that the Yıldız Holding is today. The strength of its competitiveness has resulted in Yıldız Holding forming equal partnerships with many important leading world companies. An excellent example of Yıldız Holding’s success is illustrated by the partnership agreement between Ülker and Kellogg’s, the world’s largest breakfast cereal producer, during the 2000’s. As a result of the agreement, Ülker became the only brand name that was allowed to appear beside the Kellogg’s name on labels of its products.

At the beginning of the 90’s, when Yıldız Holding adopted a strategy to branch into new sectors, its first venture into partnership with a foreign company was realized in 1993 by signing an agreement with Europe’s largest producer of starch, Cerestar. Instead of having to buy all their raw materials from various suppliers, the companies of the holding could now obtain some raw materials from Pendik Nişasta Sanayi (PNS), a new company which had been formed by the partners, which then became Turkey’s largest producer of natural and processed starch.

Another foreign partnership agreement was signed in 2003, between Yıldız Holding and the Swiss baby food company, Hero. The agreement resulted in the establishment of the first baby food manufacturing facility in Turkey. In 2005, the American company, Kellogg’s, signed a partnership agreement with Yıldız Holding and this led to the establishment of Kellogg Med, a new company that began production of breakfast cereal in Turkey.

In 2009, one of Europe’s largest chewing gum manufacturers, Gumlink and Yıldız Holding established the Continental Confectionery Company to meet the growing demand for chewing gum and candy by surrounding countries. A year later, in 2010, Yıldız Holding signed an agreement with Europe’s leading tea manufacturer, Laurens Spethman Holding A.G. & Co.KG (LSH) and the two groups established a company, Milford Yıldız.

Again in 2010, Yıldız Holding entered into an agreement with the world’s leading spice company McCormick, with the intention of forming a new company. This was followed later that year by a partnership agreement between Yıldız Holding and the leading European producer of fruit juice, the Eckes-Granini Group. Under the terms of the agreement, the companies have established another new company to manufacture fruit juice.

In 2011 two new global partnership agreements were signed. As a result of one agreement, 50% of Komili Kağıt A.Ş was purchased by the giant Swedish hygiene and paper company, SCA (Svenska Cellulosa Aktiebolaget). The new company will be responsible for the production and marketing of Yıldız Holding’s line of brand name personal care products. The strong distribution network and local production power of Komili Kağıt was combined with SCA’s expertise in R&D and brand name development.
