SandGrain is a Dutch deep-tech company founded in 2019 that develops CyberRock, a patented hybrid hardware-software platform for post-quantum resilient security in IoT devices.[1][2][5] It serves industries like industrial IoT, critical infrastructure, automotive, high-tech manufacturing, and aerospace & defense by solving cybersecurity vulnerabilities through real-time device authentication using a physically unique, immutable IC token paired with a scalable cloud platform, ensuring simple integration, low cost of ownership, and compliance with regulations like the EU Cyber Resilience Act and NIS2 Directive.[1][2] The company recently raised €13.5M in Series A funding on December 9, 2025, led by Innovation Industries with participation from BOM, Invest-NL, and DeepTechXL, to fuel global expansion amid rising IoT cyber threats and quantum risks; CyberRock is already deployed in field applications, showing strong growth momentum.[1][5]
SandGrain was founded in 2019 in Delft, Netherlands, by industry veterans including Pieter Hooijmans (CTO), Casper Juffermans (Process Technology), and Jeroen Doumen (Security Architect), who brought decades of experience in semiconductors, cybersecurity, SaaS, cloud, and chip manufacturing from multinationals to startups.[4][5] The idea emerged from recognizing identity verification as a critical vulnerability in the expanding IoT ecosystem, where billions of connected devices face escalating cyber-attacks; the team merged hands-on expertise to create a universal authentication solution combining hardware "bar coding" with cloud management.[2][4] Early traction built on this foundation, leading to real-world deployments in industrial and critical sectors, culminating in the recent €13.5M Series A to scale globally.[1]
SandGrain rides the explosive growth of IoT—billions of devices connecting worldwide—amid surging cyber threats, regulatory mandates (e.g., EU Cyber Resilience Act, NIS2), and quantum computing risks that obsolete traditional certificate-based security.[1] Timing is ideal as boardrooms prioritize IoT cybersecurity, with market forces like increasing attacks on industrial and critical infrastructure favoring economical, deployable solutions over complex alternatives.[1][2] In a crowded field with competitors like Armis Security, SandGrain differentiates via hardware-anchored simplicity, influencing the ecosystem by enabling secure scaling of IoT in high-stakes sectors and restoring trust in connected networks.[1][6]
SandGrain is poised for accelerated global rollout post-Series A, targeting large-scale adoption in industrial IoT, critical infrastructure, and aerospace with CyberRock's field-proven resilience.[1] Trends like quantum threats, stricter regulations, and IoT proliferation will propel demand, potentially expanding into automotive and smart devices while evolving influence through partnerships and IP leadership in hardware-rooted security.[1][2] As the "bar coding for security," SandGrain could redefine economical IoT trust at scale, turning today's bottleneck into tomorrow's standard.[2][4]
