Wultra Secures €3M to Safeguard Financial Institutions Worldwide from Quantum Computing Risks

Prague-based cybersecurity company Wultra has raised €3 million in funding to develop and scale quantum-resistant security solutions for banks and financial institutions, positioning itself at the forefront of the fight against next-generation cyber threats. The funding round was led by J&T Ventures, with participation from Depo Ventures, Nation 1, and other strategic investors focused on deep tech and financial security.

As the world edges closer to the reality of quantum computing, concerns are mounting around the vulnerability of current cryptographic systems, particularly in sectors where data confidentiality and transactional integrity are critical. Wultra is addressing this growing risk with its suite of security technologies specifically designed to defend against attacks that could one day be powered by quantum computers.

“We are entering a new era where traditional encryption methods will no longer be enough,” said Petr Dvořák, CEO and co-founder of Wultra. “With this funding, we’re investing in quantum-resistant solutions that will ensure our banking and fintech clients are not just compliant—but prepared for the future of cybersecurity.”

Wultra’s solutions are already used by dozens of European financial institutions, protecting millions of users through technologies like secure authentication, transaction signing, anti-malware SDKs, and digital onboarding tools. With the fresh capital, the company will expand its product line to include post-quantum cryptography (PQC) capabilities and develop tools to help banks transition safely and smoothly into the quantum-secure era.

Quantum computers, once they reach maturity, are expected to break much of the encryption that secures digital communications today. Experts warn that malicious actors could already be harvesting encrypted data today with the intention of decrypting it once quantum capabilities become viable—a concept known as “harvest now, decrypt later.” Wultra aims to eliminate this risk by introducing cryptographic methods that are resistant to both classical and quantum attacks.

“Our clients rely on us to stay several steps ahead of emerging threats,” said Jakub Mrozek, Wultra’s CTO. “The transition to quantum-safe infrastructure is not optional—it’s inevitable. This funding will accelerate our R&D and enable seamless integration of PQC into our current offerings.”

Investors backing Wultra see the move toward quantum readiness as both urgent and highly scalable.

“The financial industry is waking up to the quantum threat, and Wultra is perfectly positioned to lead this transition,” said Martin Hanzl, partner at J&T Ventures. “We believe the team’s deep experience in digital banking security, combined with their forward-looking approach, gives them a unique edge in the market.”

In addition to scaling its R&D efforts, Wultra plans to grow its engineering and go-to-market teams across Europe. The company is also exploring partnerships with academic institutions and standards bodies to contribute to global quantum-safe frameworks.

Wultra’s timing aligns with increasing pressure from regulatory bodies around the world. Agencies like the U.S. National Institute of Standards and Technology (NIST) are in the process of standardizing post-quantum cryptographic algorithms, and the European Union has begun promoting quantum-safe migration strategies for key industries.

“Security is no longer just about stopping today’s attacks—it’s about anticipating tomorrow’s,” said Dvořák. “Quantum computing will be a once-in-a-generation disruption, and we’re building the defenses now so that our clients don’t get left exposed.”

The company’s roadmap includes a quantum-safe API gateway, quantum-hardened digital identity services, and integration of PQC into its mobile security SDK—ensuring that both backend infrastructure and user-facing applications are protected from future threats.

As the cybersecurity landscape continues to evolve at breakneck speed, Wultra’s focus on building resilient, next-gen solutions places it at the center of a global conversation about digital trust, privacy, and long-term preparedness.
