German authorities’ investigations in the Stasi archives found a 350-page report referring to agent “Rocco” (“953/63”) and later “Kaskade” and “Krokus”. It was alleged that “Rocco” was the code name for Sokratis Kokkalis, allegedly recruited on 25 January 1963. Kokkalis was alleged to have subsequently bribed Greek officials in order for the national telecommunications company of Greece to purchase East German telecommunications equipment.

Kokkalis founded Intracom in 1977 as a telecommunication equipment supplier and manufacturer. The company played a leading role in the modernization of telecommunication infrastructure in Greece, especially through a partnership with Ericsson for the manufacturing of digital switches. Intracom expanded in Southeastern Europe and became a leading exporting technology Group, including the areas of software for the public sector, defense electronics and construction. It is listed in the Athens Stock Exchange since 1990.

Kokkalis founded Intralot in 1992, as a hardware and software supplier for the gaming industry. Intralot became one of the three top companies in the sector worldwide, currently with 5,400 employees and presence in 35 countries. Intralot has a strong presence in the United States, with a 20% market share for lotteries, offering its services to 11 State Lotteries.

Kokkalis also led Panafon, the mobile venture of Vodafone in Greece, immediately after the launch of mobile telephony in Greece in 1992.

Kokkalis was owner of Olympiacos BC since the early 1990s. During his presidency the basketball club won five Greek championships, three Greek Cups and one Euroleague in 1997, making the Triple Crown the same year.

Kokkalis was made a John Harvard fellow in 1997, and received awards from The Fulbright Foundation and the American Academy of Achievement for “his leadership in creating educational opportunities and building bridges of cooperation.”

The German Federal Parliament, conducted a detailed investigation and concluded in 1998, that there has been no evidence linking Kokkalis activities and his companies to East Germany.

In 2005 Intracom became a Holding company and acquired Hellas Online, an ISP provider which became a major telephony and Internet supplier. Hellas Online was sold to Vodafone in 2014. The same year Intracom Holdings divested also form the telecom manufacturing arm, Intracom Telecom. The Holding today owns three major companies, the construction branch Intrakat, the software developer Intrasoft International, which is an Oracle partner and a major supplier to the European Commission and the European Parliament, and Intracom Defense Electronics, with a strong partnership with Raytheon. The three companies today employ 2,200 people and have presence in 70 countries around the world. Most of the Group revenues come from exports and international activities.

Kokkalis is the founder and majority shareholder of Intracom Holdings, one of the largest multinational technology groups in Southern Europe, and the Chairman and majority shareholder of Intralot S.A., a gaming technology supplier and licensed lottery operator. He has established and presides over the Kokkalis Foundation, a non-profit organization that “promotes education and training, culture and social welfare, medical research and information technology, and athletics”, both in Greece and abroad. In 2015 Socrates Kokkalis net worth is estimated to be around US$1.2 billion.
