SOLIDKOSMOS, the first spin-off company established by the Research Center of the University of Piraeus, has secured €300,000 in funding from Corallia Ventures. The investment will support the commercialization of a technology that enables the assessment and enhancement of the reliability of critical computing systems used in satellites, data centers, defense applications, and artificial intelligence systems.
SK-RAFT is an advanced Electronic Design Automation (EDA) software tool that enables controlled fault injection and fault simulation on real computing hardware, allowing engineers to verify the reliability and resilience of critical systems. The global EDA market is valued at tens of billions of dollars and continues to grow rapidly, driven by the increasing complexity of artificial intelligence systems, data centers, and space infrastructures.
The investment will accelerate the transition of SK-RAFT from a mature research technology into a globally marketable commercial product. The funding will support further technical development, pilot deployments with early customers, and the company's commercial expansion into international markets for critical computing systems.
The Challenge of Reliability Verification in Critical Applications
As modern economies and societies become increasingly dependent on complex computing systems, reliability has emerged as a critical factor for safety, functionality, and operational continuity. From satellites and aircraft to data centers, autonomous vehicles, artificial intelligence systems, and medical devices, even a single fault may lead to operational failures, financial losses, or mission-critical failures.
To address this challenge, manufacturers are developing increasingly sophisticated Fault Detection, Isolation and Recovery (FDIR) mechanisms. These mechanisms must be systematically verified through controlled fault injection in real system implementations.
However, currently available approaches present significant limitations:
• RTL (Register Transfer Level) simulations can be applied from the early stages of hardware design but are often time-consuming and unable to fully capture the behavior of complex hardware-software systems.
• Physical fault-injection testing, including radiation testing, electromagnetic interference (EMI) testing, and laser fault injection, provides highly reliable results but requires specialized facilities, significant preparation time, and substantial cost.
As a result, resilience verification of critical systems remains a complex, costly, and time-consuming process.
Reliability Verification on Real Hardware with SK-RAFT
SK-RAFT enables controlled fault injection directly on real hardware by leveraging standard debugging and control interfaces and related mechanisms. This allows engineering teams to conduct extensive resilience evaluation campaigns on actual system implementations within their native test environments, without requiring access to specialized testing facilities. The approach supports systematic verification of FDIR mechanisms throughout multiple stages of the development lifecycle, from subsystem testing to final system validation.
Through this process, engineers can identify vulnerabilities and design weaknesses early, verify that protection and recovery mechanisms operate as intended, and significantly reduce the risk of costly redesigns at advanced development stages. At the same time, SK-RAFT complements physical testing methods such as radiation and electromagnetic interference testing by enabling improved preparation, optimization, and debugging before systems are subjected to specialized testing facilities. This reduces both testing costs and time requirements while improving the effectiveness of experimental campaigns.
Use of Funding and Growth Strategy
The investment will transform SK-RAFT from a technology with a strong research foundation into a fully commercial EDA solution. The funding will support:
• Expansion of support for next-generation AMD computing platforms, including the AMD Versal family.
• Implementation of pilot projects with early customers.
• Development of reference designs, technical demonstrations (demos), and specialized technical documentation, including application notes.
These activities will strengthen the deployment of the technology across FPGA-based systems, processors (CPUs), and artificial intelligence accelerators used in data centers, edge computing applications, space systems, and high-performance AI platforms.
SOLIDKOSMOS will initially focus on aerospace applications based on FPGA technologies operating under highly demanding environmental and reliability requirements. Its long-term strategic objective is to establish SK-RAFT as an internationally recognized EDA tool for the assessment, verification, and enhancement of reliability in critical computing systems serving the aerospace, defense, data center, automotive, and artificial intelligence sectors. 
Dr. Dimitris Agiakatsikas, Co-Founder and CEO of SOLIDKOSMOS, stated:
"As modern computing systems assume increasingly critical and autonomous functions, reliability is becoming a strategic requirement. From satellites and defense systems to data centers and artificial intelligence applications, the ability to predict, detect, and manage faults is essential for safety and mission success. With SK-RAFT, we enable engineers to inject controlled faults into real hardware, assess system resilience, and verify the effectiveness of protection mechanisms before deployment in operational environments. Corallia Ventures' investment allows us to accelerate the transition of a technology born from years of research into a globally competitive commercial product."
Professor Michalis Psarakis, University of Piraeus Professor, Co-Founder and CTO of SOLIDKOSMOS, stated:
"SOLIDKOSMOS emerged from a long-standing research effort at the Embedded Computing Systems Laboratory of the University of Piraeus, where we have been developing state-of-the-art technologies for the reliability of critical computing systems for more than fifteen years. Corallia Ventures' investment confirms that knowledge generated within Greek universities can be transformed into innovative solutions with international reach and tangible industrial value. For us, SOLIDKOSMOS also serves as a vehicle for transferring know-how from research to the marketplace, creating new opportunities for our students and researchers."
Professor Michail Sfakianakis, Rector of the University of Piraeus, stated:
"The establishment and funding of SOLIDKOSMOS, the first spin-off company of the University of Piraeus, marks a historic milestone for our institution. It demonstrates in practice that the academic excellence and pioneering research produced within our laboratories can be successfully connected with entrepreneurship and the global high-technology market. As a university, we remain firmly committed to supporting innovative spin-offs that create new opportunities for our researchers, generate highly skilled jobs in Greece, and strengthen the country's position on the global deep-tech landscape."
Dr. Jorge-A. Sanchez-P., Partner at Corallia Ventures TT, stated:
"SOLIDKOSMOS is an outstanding example of how Greek research excellence can be transformed into deep-tech products with global commercial potential. At a time when computing system reliability is becoming increasingly critical for space, defense, and artificial intelligence applications, the ability to verify system resilience early and under realistic conditions is more valuable than ever. SK-RAFT bridges an important technological gap between traditional simulations and costly physical testing by enabling evaluation on real hardware with greater speed, accuracy, and cost efficiency. We believe the company possesses both the technological foundation and the international potential to become a significant player in the reliability technologies sector."
