With the evolution of IoT, secure, scalable, and efficient connectivity is more critical than ever. Data authenticity transmitted from IoT devices to the cloud is essential.
We enable our customers to confidently deploy large-scale IoT solutions and develop next-generation connected products with access to best-in-class eSIM and iSIM technologies.

2009 Simulity Labs Ltd is incorporated pioneering eSIM technology
2017 Arm acquires Simulity Labs Ltd and founds the Kigen product group, to address how to drive standardised security in IoT to reach 1 trillion devices
2019 Kigen pioneers the integrated SIM within Arm, announced in partnership with Vodafone IoT at MWC’19.
2020 As eSIM standardisation matures and momentum for iSIM grows, Kigen sets out to separate from Arm to widen access to cellular security
2021 Kigen becomes a SoftBank Vision Fund company.
We work with chipset makers, device manufacturers, mobile network operators, solution and application providers to support innovation that results in ease and peace of mind for all users.

















































Together with our partners, we enable customers to leverage IoT technology delivered through eSIM and iSIM capabilities.

We believe in a world where all connected things and their data flows are authenticated at the very get-go, so we found inspiration for our company name in the Japanese word Kigen which means ‘origin’ or ‘genesis’.
Security is the foundation of trust in our digital society. Our customers and partners work with us to proactively protect their digital assets, be that the right to use a connectivity service or application data flowing from chip-to-cloud.
We are laser-focused on IoT-enabled digital transformation by simplifying and democratizing digital security, together with our partners.
