From fighter jet maintenance to crypto shares: why a former air force officer is revolutionising defence financing Michael combines the best of both worlds: an in-depth understanding of defence technology and innovative financial expertise. His career began in the German Air Force, where he served as a technical officer and systems engineer responsible for the operational readiness of TORNADO and F4-F PHANTOM fighter aircraft. At the System Support Center Eurofighter, he developed software for critical systems and worked closely with the defence industry. This military experience not only provided him with technical know-how and leadership skills, but also a unique understanding of the challenges in the European defence sector. After his time in the air force, he worked as a management consultant on digital transformation processes and developed innovative business models – the perfect preparation for his role at tacct. ‘I am convinced that technology is the key to a secure and peaceful future. With tacct, we want to promote the best minds and the most innovative technologies to make Europe more independent and resilient. We not only invest capital, but also make a concrete contribution to Europe's strategic autonomy.’ With tacct, Michael combines his military expertise with financial innovation – for a secure, sovereign Europe.

The Architect of European Defense Innovation: From Air Force Officer to Pioneer in Defense-Tech Financing Martin Stoussavljewitsch embodies the perfect symbiosis of military expertise and visionary entrepreneurship—building a bridge between innovation and security for Europe. His career began in the Air Force, where he developed a deep understanding of the operational needs of modern armed forces as an officer and systems engineer. Later, as Principal Armaments Officer at the European Defence Agency (EDA) in Brussels, he spent eight years coordinating multinational armament projects and shaping strategic research agendas for future technologies such as unmanned aerial vehicles and Future Air Combat Systems. These experiences made him a specialist in the interface between defense requirements and technological innovation and the driving force behind tacct. Together with his twin brother Michael, he founded ecrop GmbH, the company providing the technology for the tacct platform. At the same time, Martin plays a key role in ArsenalX, an initiative dedicated to building European innovation hubs for defense technology. His extensive network and unique expertise make him the ideal bridge-builder between defense-tech startups and the capital market. Europe’s security and technological sovereignty are inseparable. With tacct, we are building a bridge between the financial world and the defense industry - one that accelerates innovation, enables investment, and strengthens collaboration across Europe. It’s time to take the future of defense into our own hands. With tacct, Martin is realizing his vision: the democratization of defense financing and the strengthening of European strategic autonomy - one security at a time.

The Code Architect of Defense Financing: How a Blockchain Pioneer is Programming the Foundation for Europe’s Defense-Tech Future Tobias Rentsch is the technological backbone of tacct—the lead developer who translates the vision of a revolutionary financing platform for the European defense sector into functional systems. With his extensive expertise in software development, Tobias has established himself as a specialist in complex, scalable IT architectures. His career is defined by the successful execution of demanding projects where security and reliability are paramount—essential qualities for a platform that handles sensitive data and high transaction volumes.

At tacct, he is responsible for the platform’s technical design, implementation, and continuous development, ensuring the highest standards of security, user experience, and regulatory compliance. He sees the collaboration with ArsenalX as a perfect synergy: while the innovation centers produce groundbreaking defense technologies, tacct builds the financial infrastructure to scale and distribute these innovations. "I believe in the power of technology to change the world.
