The Swiss post-quantum-crypto firm has lifted its WeCan stake from 28% to majority and committed CHF 5M to accelerate AI-compliance tooling for Pictet, Lombard Odier and Barclays.
Geneva-based SEALSQ has acquired a majority equity stake in WeCan Group, lifting its position from the 28% taken in October 2025 and committing a further CHF 5m ($6.1m) to accelerate the joint development of an AI-powered compliance co-pilot built on post-quantum cryptography for the global financial industry.
The investment is being made through SEALSQ’s dedicated Quantum Fund, an internal strategic vehicle the company set up to back early-stage quantum-computing and quantum-security companies.
The customer base WeCan brings to the platform is the part that makes the announcement substantive. The company already counts Pictet, Lombard Odier, Edmond de Rothschild, Syz and Barclays among its private-banking clients for its existing know-your-customer infrastructure, which has been operational across several Swiss tier-one wealth managers since 2020.
The WeCan compliance stack uses blockchain-based document verification to handle the KYC and AML data-sharing that private banks have historically struggled to coordinate, even when serving overlapping client books. SEALSQ’s majority position now puts that customer base alongside SEALSQ’s own quantum-resistant Hardware Security Modules (HSMs) and post-quantum-cryptography (PQC) IP.
