SandGrain completes 1.3Mio seed investment round.

Eindhoven, The Netherlands, April 4th 2023:

SandGrain BV, an Eindhoven based start-up that focuses on ‘Trusted Authentication’, a new solution for security and circularity – is pleased to announce that they have completed a €1,3Mio seed investment round.

Why trusted authentication matters:

Due to the ever-increasing connectivity of systems worldwide, linked to the continuously extending (Industrial) Internet-of-Things (IIoT), trustworthiness of the identity of any connected system is fundamental for required cybersecurity.

Trusted Authentication, the undisputed verification of an identity, is the cornerstone of this vulnerable ecosystem that currently lacks any well-established, robust standard, determining how the different parts of the network are identified. Authentication that is dearly required before valuable data is exchanged, or critical operations are commanded. Due to this lack of proper authentication, today’s connected systems are frequently hacked; and modules are either illegally copied and/or untraceable throughout their lifecycle for proper recycling. Currently this means that these connected systems suffer from unverified configurations, risk becoming unreliable, and their maintenance is unnecessarily expensive.

Our solution is broadly applicable and infinitely scalable, potentially serving billions of identities.

Pieter Hooijmans, SandGrain founder and CTO, says: “When one targets a solution that can be deployed globally, being infinitely scalable, while providing secure solutions, it has to be designed robustly with risks minimized. With our team of industry veterans, complementing each other’s different technology domains, SandGrain is uniquely positioned to make this happen”.

“We are excited to invest in SandGrain because we see great potential in their disruptive approach to enhancing security in the fast growing industrial ‘Internet of Things’ applications. In addition, we believe that the team has the potential to play a crucial role in the deployment of circular economy concepts across various industries.”; said Guus Frericks managing partner of VC-fund DeeptechXL – Dutch deep-tech investment fund, which has declared their commitment to invest in ‘trusted authentication’.

With this investment, we will quickly make the jump to accelerated product development, ready to start widespread test pilots with several interested companies and government bodies.

By the end of this year, we plan to have our SandGrain Solution ready for functional introduction in the market. This enables us to grow our network of partners participating in a more in-depth application analysis of our unique solution. Our aim is to eliminate the gaps in the current trusted authentication and cybersecurity market, as well as provide a solution promoting greater circularity.

Safe and secure – no matter what application

We provide a universal authentication platform for any connective device.

Today, cyber-attacks are a real concern. We believe in restoring trust and piece of mind in an ever-changing and expanding Internet-of-Things.

We have created a unique solution that can be applied universally to any connective device within the Internet-of-Things. It combines the best of both worlds: a secure cloud platform linked to a token physically attached to the device.


The secure cloud platform providing state-of-the-art cyber security and required software services.

  • Generates, assigns, and issues unique identities for hardware tokens
  • Validates authentication requests from tokens in de field.
  • State-of-the Art cyber-security
  • Infinitely scalable
