ResQuant is a Lodz, Poland-based deep-tech cybersecurity startup founded in 2020 by Dr. Michał Andrzejczak (PhD in Computer Science at Military University of Technology Warsaw) and Tomasz Szcześniak, providing the only hardware-implemented post-quantum cryptography solution in the EU. ResQuant develops proprietary hardware PQC accelerators and secure element chiplets built on GF 22nm technology for next-generation connected devices. The company offers single algorithm implementations including Dilithium, Kyber, SHAKE, AES, XMSS, and SPHINCS+ compliant with NIST post-quantum cryptography standards. ResQuant raised EUR 275K from accelerators and investors including Lighthouse Ventures and Invento Capital, supporting ESA projects developing post-quantum cryptography for satellite communications. ResQuant addresses quantum computing threats to current cryptographic systems through hardware-accelerated post-quantum encryption for defense, space, IoT, and critical infrastructure sectors.
