The Group’s Chairman and CEO, Kostas Nembis, during his participation in the Growthfund Investor Summit 2026.According to Mr. Nembis, more than 25% of the company’s processes are already supported by AI tools—that is, they are AI-augmented—and the goal is to increase this percentage to 40% by the end of the year.
On the other hand, the head of OTE made it clear that the group did not “discover” artificial intelligence in the last two years. Rather, it had been using aspects of AI, such as machine learning, primarily in relation to network operations.
However, what has changed over the past two years is that Artificial Intelligence has evolved into a strategic pillar of the group. “Our goal is to evolve into a ‘digital first’ and, gradually, an ‘AI-native’ company, making exemplary use of artificial intelligence,” emphasized Mr. Nebis.
Among other initiatives, OTE is developing AI assistants for various functions, leveraging conversational AI in customer service, and providing its employees with AskT, an innovative AI assistant based on OpenAI technology.
Regarding businesses, the group is building a portfolio of specialized solutions with the support of its parent company, TELEKOM. For example, it has launched new data center infrastructure for business cloud services, including GPU-as-a-Service solutions for artificial intelligence applications. This gives businesses access to high computing power for AI applications without having to build their own infrastructure from scratch.
As for individual users, Mr. Nebis stated that the group’s goal in this area is democratization. As he noted, “OTE offers leading AI tools (e.g., Perplexity, ElevenLabs, Picsart) through Magenta AI, which is available on the COSMOTE TELEKOM app. Our goal is to put AI in everyone’s hands.”
Coverage on fixed and mobile networks
At the same time, the head of OTE also spoke about the role of digital infrastructure in the country’s development, stating that “we cannot talk about an AI-ready economy without AI-ready network infrastructure.” In fact, as he put it, “infrastructure—and specifically networks—function like the highways on which all applications, in general, and AI applications, in particular, run.”
He explained that the demands of AI applications are constantly multiplying and require networks with minimal latency, increased upload capacity, dynamic slicing, high security, and computing power.
When asked about Greece’s position compared to other countries in terms of telecommunications infrastructure, Mr. Nebis replied that “In the mobile sector, our networks are a source of pride, not only compared to the rest of Europe, but in certain areas even compared to the rest of the world.”
The head of OTE cited a recent European Commission report, according to which 5G network coverage in Greece is 2 to 3 percentage points higher than the European average, which, he said, is due to investments by the OTE Group.
Nationwide population coverage of OTE’s 5G network exceeds 99%, and that of 5G SA exceeds 82%. Mr. Nebis argued that thanks to this 5G SA network, Greece ranked first in Europe and fourth in the world in terms of download speeds, according to a recent analysis by Ookla.
However, when asked about the areas where Greece is lagging behind, the head of OTE replied that “we still have work to do on fixed-line networks.” He cited a recent European Commission report, which indicates that there is significant room for improvement in infrastructure. However, as the report itself noted, it also reflects the high growth rate the country has achieved.
By way of example, he noted that fiber-optic internet is now available in 60% of the country, compared to 46% a year ago. “We’re talking about an annual growth rate of around 30%, which is four times faster than the rate in the rest of Europe,” she commented.
At the same time, he pointed out that in the past year alone, Greece has moved up 23 spots in the global ranking of broadband speeds offered by the country’s networks. “These are significant improvements, though this does not mean we have reached our destination,” he clarified.
In this context, Mr. Nebis emphasized that OTE’s infrastructure currently covers more than 2.2 million households and businesses and is continuously expanding, with the goal of reaching 3.5 million by 2030.
