Firgun Ventures is a London-based venture capital firm dedicated to backing the world’s most advanced quantum technology startups at the early growth stages. Founded by Dr Kris Naudts and Zeynep Koruturk, the firm blends deep scientific rigor with entrepreneurial and financial expertise. Firgun positions itself as the first VC fund specifically focused on Series A and Series B quantum companies, supporting founders who have successfully transitioned from lab breakthroughs to early commercial traction. Its global approach is reinforced by an advisory council that includes leading experts from Cambridge, Oxford, MIT, Google, the European Investment Bank, and the Wellcome Trust.
Firgun invests globally in quantum computing, quantum sensing, quantum communications, and quantum cryptography, with related applications across healthcare, climate science, finance, and cybersecurity. The firm targets founders whose scientific innovations have matured into commercial products and who require specialized capital to scale into global markets.
Firgun Ventures launched its first dedicated quantum technology fund in 2025, targeting $250 million with a $70 million first close anchored by the Qatar Investment Authority. Marketed as the first VC fund focused exclusively on early growth-stage quantum startups, the vehicle is designed to support founders at the critical inflection point between scientific validation and commercial scale.
The fund aims to invest in Series A and Series B companies across quantum computing, sensing, and communications, along with downstream applications in healthcare, finance, climate science, and cybersecurity.
Firgun’s investment model leverages its founders’ long-standing presence in the quantum ecosystem, including angel investments in quantum startups since 2016 and early backing of Quantinuum (formerly Cambridge Quantum Computing), one of the world’s most valuable private quantum companies.
The fund also integrates a global advisory council of academic and industry experts who support technical due diligence and guide portfolio companies through the complexities of frontier quantum innovation, ensuring both scientific robustness and commercial viability.
