Funding round led by Innovation Industries with BOM, Invest-NL, and existing investors

On December 9, 2025 Dutch deep-tech company SandGrain announced the successful raise of €13.5 million in a Series A funding round. This investment will accelerate global expansion of SandGrain’s CyberRock solution, which delivers advanced security for IoT devices, focusing on key sectors such as industrial, critical infrastructure, and aerospace & defense. The round was led by Innovation Industries, with participation from Brabantse Ontwikkelings Maatschappij (BOM), Invest-NL, and existing investor DeepTechXL.


With billions of connected devices coming online worldwide, cybersecurity has become a boardroom priority. New regulations like the EU Cyber Resilience Act and the NIS2 Directive are raising standards for device security, while emerging quantum computing threats challenge traditional certificate-based methods.
CyberRock addresses these challenges by providing hardware-grade post-quantum resilient IoT security at reduced total cost of ownership through:

• A symmetrical challenge-response authentication scheme that verifies device identity using a hard-coded, immutable and globally unique ID built into each device (hardware token), linked to an enclave holding the corresponding secret keys.
• A secure cloud platform that manages real-time identity and authentication of devices at a reduced total cost of ownership.
• Compliance with industry-leading standards including the EU Cyber Resilience Act (CRA), NIS2 Directive, digital passports, and sustainability acts.

SandGrain’s patented hybrid hardware-software approach ensures simple integration, streamlined provisioning, low total cost of ownership and scalable, future proof protection. Deployed in multiple industrial, critical infrastructure, and aerospace & defense applications, CyberRock is demonstrating readiness for large-scale rollouts in critical environments worldwide.

“Complexity and cost have long been the bottleneck in IoT security,” said Joeri Voets, CEO of SandGrain. “With SandGrain’s CyberRock already protecting devices in the field, this investment enables us to scale faster and deliver the simplicity and future resilience the market urgently needs.”

“SandGrain solves a large challenge in IoT: making strong security economical at the end-node”, said Rogier Ketelaars, Investment manager at Innovation Industries. “By avoiding certificates and with a simple pre-provisioned unique Root-of-Trust, device authentication becomes simpler and cost-efficient. Their solution is easy to deploy today and designed with post-quantum resilience in mind giving customers confidence in their security tomorrow.”
