Jan de Vries · 2026-06-02

Wecan Group, a Geneva-based startup that helps private banks and financial institutions stay compliant, just announced that SEALSQ Corp—a post-quantum cybersecurity company—has bought a majority stake in it. This comes a year after SEALSQ first invested 28% in the company. As part of the deal, SEALSQ will pour about $5.9 million (converted from €5.4 million) into speeding up Wecan Group's growth and rolling out next-gen compliance tools and post-quantum security for the global finance world. Vincent Pignon, founder and CEO of Wecan Group, said, "Wecan Group was created to help financial institutions manage trust, compliance and sensitive client information more efficiently. With SEALSQ as a majority shareholder and strategic technology partner, we are entering a new phase of growth. This investment will allow us to accelerate the deployment of our Compliance Copilote and strengthen our infrastructure with post-quantum security capabilities, providing banks and financial institutions with future-ready solutions for client lifecycle." ### What Wecan Group Does Founded in 2015 by Dr. Vincent Pignon, Wecan Group's mission is simple: help financial institutions handle compliance more securely and efficiently. Their platform orchestrates onboarding, change-of-circumstance updates, and periodic reviews for regulated clients—whether they're individuals, companies, trusts, or other entities. The company offers tools for digital client onboarding, KYC and AML analysis, account openings, contract generation, and periodic reviews, all while keeping everything auditable and compliant. Some of their big-name clients include Pictet, Lombard Odier, Edmond de Rothschild, Syz, and Barclays. ### Why SEALSQ Matters SEALSQ specializes in post-quantum tech—hardware and software designed to protect against future quantum computer attacks. They build semiconductors, PKI (Public Key Infrastructure), and provisioning services, all focused on quantum-resistant cryptography. As quantum computers get more powerful, traditional encryption methods like RSA and ECC become vulnerable. SEALSQ claims to be leading the charge in developing post-quantum semiconductors that protect sensitive data in applications like multi-factor authentication tokens, smart energy, healthcare, defense, IT networks, automotive, and industrial control systems. By embedding Post-Quantum Cryptography into their chips, they aim to keep organizations safe from quantum threats. ### The Bigger Picture Carlos Moreira, CEO of SEALSQ, explained: "Our majority investment in Wecan Group represents a significant step in SEALSQ's strategy to bring post-quantum security to the most sensitive sectors of the global economy. Financial institutions and digital asset platforms are entering a new era in which cybersecurity, compliance automation, digital identity and trusted AI must converge. At the same time, cryptocurrencies and blockchain infrastructures must evolve toward quantum resilience to preserve long-term trust and security." He added, "By combining SEALSQ's post-quantum technologies, Wecan Group's expertise in private banking compliance infrastructure and WISeKey's trusted digital identity ecosystem, we aim to deliver a secure and scalable trust platform for the financial industry and the digital asset economy worldwide." ### What's Next Through this majority stake, Wecan Group and SEALSQ plan to fast-track an AI-powered Compliance Copilote built on a secure post-quantum foundation. The platform will integrate advanced Post-Quantum Cryptography (PQC) technologies and quantum-resistant features. It's a clear signal that the financial industry is getting serious about future-proof security. If you're in banking or fintech, this is a trend worth watching closely.
