Cambridge-based Arm spin-out Kigen secures €11.5 million to scale eSIM cybersecurity

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

The growth debt investment will support Kigen’s next phase of growth across the UK, EU, and US. 

“This investment allows us to accelerate our next phase of growth with confidence. Our customers are looking for practical ways to strengthen cyber resilience, simplify regulatory readiness, and manage secure connectivity over the long term. This funding helps us move faster to support them with trusted, future-ready solutions,” said Vincent Korstanje, CEO of Kigen. 

Originally a spin-out from Arm, Kigen has operated independently since 2020 with offices in Cambridge, Belfast, Northern Ireland, and Noida, India. The company enables businesses to expand their Internet of Things (IoT) deployments by integrating trust and security through SIM, eSIM, and iSIM technologies. It claims that its technology allows the option to choose from 200+ terrestrial and satellite networks, with proven interoperability on leading chipsets and modules.

According to Kigen, its capabilities are relevant for organisations that need to demonstrate secure connectivity architecture and long-term maintainability. The company works with manufacturers worldwide to provide secure, GSMA-certified eSIMs and management solutions across consumer, M2M, and IoT environments, with direct access to more than 200 terrestrial and satellite networks. 

Kigen states that it has also positioned its latest eSIM offerings around security patching and updates at scale. It claims that this makes secure updates, auditability, and long-term support more straightforward and predictable for manufacturers managing products over many years. 

Its platform is increasingly delivered via a SaaS model, providing customers with flexible, usage-based access to OS licensing, management tools, and professional services. Kigen is backed by Arm, SoftBank Vision Fund 2, and SBI Group.

Usman Ali, Partner, Venture Debt Fund at Salica Investments, said, “The team has built a highly differentiated platform at the intersection of connectivity and cybersecurity, with strong relevance for manufacturers and enterprises navigating a more demanding regulatory and operational environment. We are delighted to support Kigen as it scales across critical sectors and international markets.”

Salica was originally founded as an investment firm focusing on promising businesses. It has evolved into a set of private market funds investing in equity and debt across multiple sectors and stages, predominantly across the UK.
