Wultra raises €6.8M to make finance world quantum-proof
The Prague-based security firm raised €3M last year. Now it's back for more than twice that. Next stop: the Middle East and the US.
Post-quantum cryptography just moved from research papers to real business. Wultra, our portfolio company building post-quantum authentication for banks and fintechs, has closed a €6.8 million Series A, roughly a year and a half after its €3 million round in January 2025.
“Last year was a highly dynamic period for Wultra. We expanded our product portfolio beyond authentication to cover the broader digital identity journey, from onboarding and identity proofing to user authentication, transaction authorization, and electronic signatures. We grew our team by nearly 50%, established a presence in Singapore, and now support more than 70 clients across 25 countries worldwide,” said Petr Dvorak, Founder & CEO of Wultra.
Seventure Partners led the round, joined by ARIADNEXT founders Marc Norlain and Guillaume Despagne and existing investors J&T Ventures and Elevator Ventures.
Wultra helps financial institutions replace legacy authentication methods with phishing-resistant, post-quantum technologies. The proceeds will go toward scaling its digital identity platform, accelerating development of digital identity wallet capabilities for the European Digital Identity Wallet (EUDI Wallet) ecosystem, and expanding into new markets. Having established its regional hub in Singapore, Wultra now plans to move into the Middle East and the United States, alongside team growth and a stronger focus on large strategic customers.
“Banks are no longer asking whether they need post-quantum authentication and digital identity – they’re asking how to deploy it and include post-quantum-readiness and crypto-agility as a mandatory requirement. This investment allows us to accelerate that transition and expand to even more markets,” adds Petr.
The timing is no accident. Organizations worldwide are modernizing their digital identity systems to address AI-enabled identity fraud, including deepfakes, while accelerating their transition to post-quantum security following NIST’s publication of post-quantum cryptography standards. In August 2025, Wultra was named the only Sample Vendor for Post-Quantum Authentication in the Gartner Hype Cycle for Digital Identity 2025.
“The post-quantum era is closer than everybody thinks. Every encrypted transaction happening today can be harvested now and decrypted later, and banks cannot retrofit trust once it’s broken. Ignoring that is not an option, it is reckless. Post-quantum is simply the next security standard. This €6.8M round shows the market has stopped asking whether the threat is real and started asking who is ready. Congratulations to the Wultra team, this one is well deserved,” says Martin Drdul, co-founder and General Partner at Tensor Ventures.
