Salica Investments has provided Kigen with £10 million of growth debt to fund expansion across the UK, the EU and the US. It announced the facility on 30 April 2026 from London and Cambridge and said the transaction is its first backing of a company in Cambridge's Silicon Fen.
Kigen, led by Chief Executive Vincent Korstanje, writes eSIM security software. Originally a spin-out from Arm, it has operated independently since 2020, with offices in Cambridge, Belfast and Noida.
Salica said manufacturers and enterprises are facing rising cybersecurity demands, increasing regulatory pressure and a need to secure connected products across their full lifecycle, and that the capital will support Kigen's next phase of growth.
Existing backers named in the announcement are Arm, SoftBank Vision Fund 2 and SBI Group. In June 2025 Kigen said SBI Group had made a strategic investment that joined a funding round already backed by Arm and SoftBank Vision Fund 2, with a focus on accelerating growth in industrial IoT.
Usman Ali, Partner in Salica's venture debt fund, said: "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."
Korstanje said the facility would allow the company to accelerate its next phase of growth. "Our customers are looking for practical ways to strengthen cyber resilience, simplify regulatory readiness, and manage secure connectivity over the long term," he said.
Salica is a London multi-strategy private markets firm that invests across equity and debt. Its growth debt strategy provides non-dilutive senior debt to high-growth software, advanced manufacturing and IP-rich businesses.
On 1 October 2025 Salica announced a first close of Growth Debt Fund II at £150 million, with the British Business Bank and West Yorkshire Pension Fund each committing £30 million as repeat anchors. The fund provides senior secured loans to high-growth UK companies in software, IP-rich hardware and advanced manufacturing.
