KIEFER is aiming for investments totaling approximately 150 million euros over the next two years, according to remarks made by the CEO of the Greek technology company, Christos Petrocheilos, during a presentation held at the company’s facilities.
KIEFER began its journey in the energy sector, but today it is evolving into a major pillar of the domestic artificial intelligence and robotics sector.
From Energy to Artificial Intelligence and Robotics
In the KIEFER model, each level fuels the next: renewable energy powers supercomputers, supercomputers train AI models, and these models become the “brain” of advanced robots.
According to Mr. Petrocheilos, since the company entered this technology sector, it has spent approximately 25 million euros on infrastructure, with funding coming from loans and equity.
The company already operates a data center in Athens and has begun construction of a second data center in Megalopolis. The €40 million project will have a capacity of 500 kW.
In terms of human resources, the group employs a total of approximately 300 people, 45 of whom work in the technology sector. As Mr. Petrocheilos noted, the team is growing on a weekly basis, and the goal is to attract Greeks living abroad.
Broadly speaking, the company is investing in the creation of a comprehensive domestic Artificial Intelligence ecosystem, with the goal of ensuring that data, computing power, human resources, and critical technological infrastructure to remain and be processed in Greece, in collaboration with NVIDIA.
As mentioned above, KIEFER’s journey began in the energy sector, with a portfolio of renewable energy projects that currently exceeds 600 MW in operation. Building on this green foundation, KIEFER is developing a comprehensive AI Factory, with the facility hosting the first NVIDIA SuperPOD supercomputing cluster in Greece.
The Application Ecosystem
On the software side, KIEFER has developed the following solutions:
Sophea AI: The company has developed Sophea AI, a comprehensive Greek artificial intelligence ecosystem, and has also introduced Sophea K1, an open-source large language model (LLM) designed for the Greek language and Greek data.
Sophea Canary ASR: The new bilingual (Greek/English) AI speech model from the company’s open-source project, which converts spoken speech into highly accurate written text while also offering direct translation from Greek to English through a single model. It ensures professional-grade accuracy in Greek (with an error rate of just 2.9% in everyday speech), incorporates specialized medical and legal vocabulary, and was trained entirely on a compact desktop device, proving that state-of-the-art speech recognition no longer requires massive data centers.
Sophea Nous: In an average organization, employees spend up to 20% of their time searching for information that already exists, scattered across dozens of different systems. Sophea Nous consolidates this knowledge: the organization “converses” with its own data in natural Greek, receives answers with references to sources, and creates specialized AI agents for each department, with the data remaining on its own infrastructure.
Sophea Meet: A specialized solution for meetings, Sophea Meet offers real-time transcription, summaries, and action item tracking in Greek. With the support of the Sophea Meet Card, it ensures accurate transcription of every word with top-quality audio and advanced noise cancellation powered by Artificial Intelligence, guaranteeing reliable transcription during in-person meetings.
According to Mr. Petrocheilos, Sophea Meet will launch on July 1 in Poland, Romania, and Bulgaria, and in September it will be released in Central Europe, including Austria, Germany, and France.
Hyperion-X: Hyperion-X is a standalone artificial intelligence platform for electricity markets. It covers renewable energy generation forecasting, balancing, and automated trading (ENTSO-E / ENEX), targeting renewable energy producers, independent power producers (IPPs), and traders.
Physical AI: The final level of the chain is Physical AI, which involves transferring Artificial Intelligence from the screen to the physical world through robotic systems. As Unitree’s sole authorized partner in Greece, KIEFER is developing the operating system for humanoid and quadruped robots that “see,” understand, and speak Greek.
The quadruped robots are designed to operate in demanding and hazardous environments, with the primary goal of protecting humans.
Their main applications include:
- Inspection of energy infrastructure and high-voltage substations
- Patrolling and monitoring critical facilities
- Monitoring the progress of construction projects and collecting field data
- Support during the installation of solar farms
- Civil protection and natural disaster response operations
In the field of civil protection in particular, KIEFER has developed a specialized four-legged robot for firefighting and emergency response operations, suitable for environments where human access is impossible or extremely dangerous.
Among other services, the company also offers robot rental. When asked about approximate prices, Mr. Petrocheilos noted that larger robots are rented more frequently, with rental rates ranging from approximately 1,000 to 1,100 euros per month.
