About
S-Transistors is a Finnish deep-tech spinout from the VTT Technical Research Centre of Finland, developing superconducting transistors intended to serve as the control-layer hardware for large-scale cryogenic quantum computers 12. The company describes its platform as a “quantum motherboard” — integrated circuits that combine the switching characteristics of transistors with the ultra-low power dissipation of superconductors 13. On August 31, 2026, S-Transistors announced a €2.6 million pre-seed round led by Lifeline Ventures, with participation from an undisclosed angel investor 1234.
