CAMBRIDGE, England, June 10, 2025 — Kigen, a global leader in eSIM and a pioneer in integrated SIM (iSIM) security solutions, today announced a strategic investment from the SBI Group, a major financial services and investment firm in Japan. This investment complements existing support from Arm Holdings and SoftBank Vision Fund 2, marking a key step in Kigen’s goal to enhance the accessibility and security of cellular technology for device manufacturers. Kigen has been at the forefront of adopting the GSMA’s new eSIM standard, currently collaborating with over 70 clients and trusted by all IoT module vendors. Its technology enables manufacturers to quickly provision secure connectivity in just two minutes using advanced factory provisioning on any SIM form factor, significantly reducing product development time. Kigen’s impact on the telecom sector led to it being named Startup of the Year 2024 by the Mobile Industry Awards.

The new funding will help Kigen expand its global presence, especially in industrial IoT, where there is increasing demand for secure and scalable connectivity in critical infrastructure, manufacturing, and smart electronics. This investment demonstrates ongoing confidence in Kigen’s vision for a secure, simplified digital future and its influence in shaping global eSIM standards.

“We are very happy to welcome SBI Group as a strategic investor,” said Vincent Korstanje, CEO of Kigen. “Their support reinforces our conviction that secure, scalable connectivity is essential for the next wave of innovation. As AI increasingly interacts with the physical world, security and trust are paramount. Kigen is helping to drive this change at a crucial time for sectors like energy, logistics, and smart manufacturing.”

Powering Industrial IoT and the Future of Physical AI

The adoption of eSIM technology, which facilitates cellular connectivity via secure components integrated into devices, is growing rapidly, especially in areas like energy, manufacturing, logistics, and connected devices. These industries face pressure to reduce complexity, scale globally, increase security, and enable AI at the edge while transforming their operations.

Kigen’s technology streamlines the deployment of connected devices across different regions, using single-SKU (Stock Keeping Unit) models that support global connectivity right away. The company’s solutions prioritize security, helping customers meet strict regulatory requirements and supporting the advancement of Physical AI, where artificial intelligence integrates seamlessly with the physical environment.

A Proven Track Record in eSIM Innovation

Since its inception, Kigen has been instrumental in defining the GSMA standards that support modern eSIM adoption.

Today, Kigen collaborates with leading device makers, manufacturers, mobile operators, and module vendors to accelerate the introduction of eSIM-enabled products to the market. The company’s platform supports the entire eSIM lifecycle, from provisioning to remote management, helping customers scale efficiently.
