CryptoNext's Milestones

2015 The French Ministry of Defense asks Jean-Charles Faugère and Ludovic Perret to integrate quantum resistant software in a communication encryption application for standard mobile phones. Following its implementation, the French MOD conducts a real life field experiment with 150 smartphones used by militaries. Its success leads to a new development project with SATT Lutech in the same year.

2016 CryptoNext’s founders submit a PQC signature algorithm in response to the NIST PQC Call to define new standards. The growing threat perceived with the progress of Quantum computing drives interest in Post-Quantum cryptography. 

2019 The growing threat perceived with the progress of Quantum computing has amplified interest in Post-Quantum cryptography. Jean-Charles Faugère, Chief Technical Officer of CryptoNext Security, and Ludovic Perret create the company in May 2019 and raise their first capital in 2020 with Quantonation Venture Capital, the first fund dedicated to Quantum Technology startups, and SATT Lutech for the Sorbonne University and INRIA.

2020 CryptoNext Security is awarded the prestigious innovation i-Lab prize by the French Investment Bank (BPI) and are the only international team to receive an award in the Chinese Association for Cryptologic Research (CACR) competition.


2021 Florent Grosmaitre, joins as Chief Executive Officer. In August, the Inside Quantum Technology organisation identifies CryptoNext as a European leader in PQC and in October, Gartner places CryptoNext Security among the five top leading vendors of Post Quantum Cryptography. CryptoNext Security's founders who did participate from inception to the NIST competition targeted at defining new standards for public key cryptography have their proposal selected to enter the final round of the competition (3rd round). CryptoNext Security is shortlisted among 1000+ start-ups as a “Future 40” most promising technology startup by Station F, the largest start-up incubator in Europe.

2022 Christian d'Orival joins as Chief Revenue Officer. CryptoNext wins the “Prix de l’Innovation des Assises 2022” , selected from a shortlist of 50 by a jury of Chief Information Security Officers at global companies. Les Assises is one of the most prestigious cybersecurity events in Europe, held every year in Monaco. In November 2022, CryptoNext is invited to join the National Cryptography Center of Excellence (NCCoE), a NIST work group dedicated to Post-Quantum migration.

2023 René Martin joins as Chief Product Officer. CryptoNext Security secures 11M€ funding, thanks to a continuous support from Quantonation, and the participation of AXA Venture Partners and Auriga Cyber Ventures, to accelerate industrialization and worldwide adoption of its Quantum Safe Remediation Solutions.
