SEALSQ Corp, a global player in quantum-resilient cybersecurity technologies, said on Monday it has expanded its Quantum Investment Fund to more than $35 million from the original $20 million to accelerate the integration of post-quantum cryptography, satellite communication, edge security, and digital identity into a unified secure infrastructure.
The fund, aimed at building a fully quantum-safe technology stack, will support SEALSQ’s long-term goal of creating a vertically integrated cybersecurity platform that spans from hardware to cloud to space.
The company said the investment strategy is designed to prepare global infrastructure for the arrival of quantum computing, which poses a significant threat to traditional encryption methods.
“This isn’t a collection of siloed investments; it’s a coordinated strategy to build the world’s first fully post-quantum secure digital ecosystem,” said Carlos Moreira, CEO of SEALSQ. “We are preparing the critical infrastructure of tomorrow, today.”
As part of the initiative, SEALSQ and its parent company WISeKey International Holding Ltd have committed approximately $12 million to develop a Post-Quantum Semiconductor Center in Murcia, Spain, in collaboration with the Spanish government’s SETT.ES program.
The facility will design and manufacture quantum-enhanced chips that serve as the foundation of SEALSQ’s secure ecosystem.
The company has also completed the acquisition of IC’Alps, a French ASIC design firm, in a transaction valued at about $14.7 million, including €10 million in cash and €2.5 million in stock.
This acquisition enables SEALSQ to control the development of custom semiconductors optimized for post-quantum cryptographic algorithms such as CRYSTALS-Kyber, per the announcement.
SEALSQ has invested $10 million in the deployment of its WISeSat.Space satellite constellation to deliver encrypted communication services across remote and underserved regions.
The satellites will support secure IoT data transfer and financial network connectivity using post-quantum encryption.
In Switzerland, SEALSQ acquired a 28% stake in WeCan Group for $3.5 million to integrate blockchain-based digital identity and KYC services with SEALSQ’s hardware systems.
An additional strategic investment of $100,000 in French startup ColibriTD gives the company early access to next-generation quantum cryptography protocols, including Quantum Key Distribution (QKD).
The company emphasized that the convergence of satellite communications, semiconductors, blockchain identity, and AI-enhanced hardware security is no longer optional, but critical to maintaining trust and protection in the quantum computing era.
The expansion of the fund also comes on the heels of SEALSQ’s recently released H1 2025 preliminary revenue update, and is aligned with its broader 2025 growth strategy.
