Arm’s Cambridge Spin-out Kigen Raises €11.5 Million to Expand eSIM Cybersecurity Solutions

Kigen, a startup based in Cambridge, specializing in eSIM and Remote SIM Provisioning (RSP) security technologies, has successfully secured €11.5 million (£10 million) in funding from Salica Investments, an investment firm based in the UK.

This growth debt investment will play a crucial role in supporting Kigen’s upcoming phase of expansion across the UK, EU, and US.

Vincent Korstanje, the CEO of Kigen, expressed his enthusiasm about the investment, stating, “This funding allows us to accelerate our growth confidently. Our customers are seeking practical solutions to enhance cyber resilience, simplify regulatory compliance, and manage secure connectivity in the long term. With this funding, we can better support them with trusted and future-ready solutions.”

Originally originating as a spin-out from Arm, Kigen has been operating independently since 2020, with offices in Cambridge, Belfast, Northern Ireland, and Noida, India. The company focuses on enabling businesses to enhance their Internet of Things (IoT) deployments by incorporating trust and security through SIM, eSIM, and iSIM technologies. Kigen claims that its technology provides the flexibility to choose from over 200 terrestrial and satellite networks, ensuring proven interoperability on leading chipsets and modules.

Kigen emphasizes that its capabilities are particularly relevant for organizations looking to demonstrate secure connectivity architecture and long-term sustainability. The company collaborates with manufacturers globally to supply secure, GSMA-certified eSIMs and management solutions across consumer, M2M, and IoT environments, offering direct access to more than 200 terrestrial and satellite networks.

Furthermore, Kigen has positioned its latest eSIM offerings around security patching and updates at scale. This approach aims to simplify secure updates, enhance auditability, and provide predictable long-term support for manufacturers managing products over extended periods.

The company’s platform is increasingly delivered through a Software as a Service (SaaS) model, granting customers flexible, usage-based access to OS licensing, management tools, and professional services. Kigen enjoys the backing of Arm, SoftBank Vision Fund 2, and SBI Group.

Usman Ali, Partner at Salica Investments, expressed his support for Kigen, remarking, “The team has developed a highly innovative platform at the convergence of connectivity and cybersecurity, with significant relevance for manufacturers and enterprises navigating an increasingly demanding regulatory and operational landscape. We are thrilled to back Kigen as it expands across critical sectors and global markets.”

Salica Investments, initially established as an investment firm focusing on promising businesses, has evolved into a series of private market funds investing in equity and debt across various sectors and stages, predominantly within the UK.
