Kigen, an eSIM and Remote SIM Provisioning security tech startup, has raised £10 million in funding from Salica Investments. The growth debt investment will support Kigen’s next phase of growth across the UK, EU, and US as enterprises and manufacturers respond to rising cybersecurity demands, increasing regulatory pressure, and the need to secure connected products across their full lifecycle.
Operating at the intersection of connectivity and cybersecurity, Kigen provides secure, GSMA-certified eSIMs and management solutions across consumer, M2M, and IoT environments, with direct access to more than 200 terrestrial and satellite networks. Capabilities are designed for organisations that need to demonstrate secure connectivity architecture and long-term maintainability, including security patching and updates at scale to support auditability and long-term product support. The platform is increasingly delivered through a SaaS model, giving customers usage-based access to OS licensing, management tools, and professional services.
Across Europe and the US, regulatory frameworks including the Cyber Resilience Act and NIST-2 are increasing expectations around secure-by-design products, vulnerability handling, coordinated reporting, cyber risk management, and lifecycle security. As connected products move deeper into critical operations and infrastructure, cybersecurity is becoming a board-level priority for enterprises and manufacturers.
Originally a spin-out from Arm, Kigen has operated independently since 2020 with offices in Cambridge, Belfast, Northern Ireland, and Noida, India. The investment marks Salica Investments’ first backing of a company in Cambridge’s Silicon Fen.
Kigen is the kind of category-defining business we look to back. The team has built a highly differentiated platform at the intersection of connectivity and cyber security, 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.
We are excited to join the high-calibre portfolio of companies backed by Salica. 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.
