Before joining TACEO, Fabian worked at the SIC Stiftung of the ISEC Institute at the Technical University of Graz, where he implemented full-stack and cryptography applications for eGovernment solutions. He earned a Master's degree in Computer Science at the same institute. For his Master's thesis, he focused on MPC, specifically developing tools to achieve general-purpose MPC from RISC-V assembly.

Florin joined TACEO in January 2024. Before that, he earned a Master's degree in Mathematics from Graz University of Technology, specializing in discrete mathematics with a particular focus on commutative and noncommutative algebra. Outside of work, he enjoys cycling and regularly attends GAK matches, though he often ends up regretting it by Monday.

Before joining TACEO, Franco worked at the SIC Stiftung of the ISEC Institute at the Technical University of Graz, where he was a cryptographic engineer focused on eGovernment solutions and the secure implementation of cryptographic algorithms on the Java platform. His work primarily involved AdES signatures and post-quantum cryptography. He completed his Master's degree in Computer Science at the same institute.

Quentin began his career in architecture and design, later co-founding a high-end furniture company before moving into Web3 and privacy tech. He worked on making ZK cryptography more accessible, growing technical communities, and running events with the ZK Hack community. At TACEO, he brings a unique blend of creative vision, technical understanding, and strategic leadership to shape the company's brand and market presence.

Roman graduated from Graz University of Technology with a Master's degree in Computer Science. He focused on the application of zk in the steel industry during his Master's thesis at the ISEC institute. During and after his studies, Roman worked for PSI Metals who provides production management solutions for the metals industry before joining TACEO in 2023.

Roman is a co-founder and the lead cryptographer of TACEO. Before that, he obtained a PhD in Cryptography at Graz University of Technology, advised by Prof. Christian Rechberger. His main research interests include privacy enhancing technologies (MPC, ZK, FHE), their intersection with symmetric primitives, and their application to real world use cases.
