Manchester-based PEAK:AIO has secured €5.7 million in funding to accelerate the global rollout of its high-performance storage platform for artificial intelligence. The round was led by Pembroke VCT, which invested €4.2 million, alongside NPIF II – Praetura Equity Finance and a Silicon Valley investor.
Founded by data infrastructure Mark Klarzynski in 2021, PEAK:AIO develops ultra-fast, energy-efficient storage software designed to solve AI’s critical bottleneck: the slow movement of data. Its systems deliver faster performance while using less energy and space than traditional solutions, helping organisations scale AI more sustainably and cost-effectively.
The fresh capital will fuel international expansion, team growth, and product development. The company has already quadrupled revenue and its partner network in the past year, with deployments at institutions including the NHS, King’s College London, the Zoological Society of London, and Los Alamos National Laboratory in the US.
Mark Klarzynski, Co-founder and CSO of PEAK:AIO said: “AI has created demands that traditional IT was never designed to handle. From the start, we built PEAK:AIO to answer those challenges, and our success in the UK quickly led to adoption in the US. This investment is about more than growth; it is about backing a UK company that is setting new standards in AI infrastructure worldwide.”
Fred Ursell, Head of Investments at Pembroke Investment Managers, said: “Every major technology wave exposes bottlenecks that hold back progress. In AI, that bottleneck is storage – GPUs sit idle while data crawls in. PEAK:AIO has built a solution from first principles that flips this equation, unlocking the full potential of AI infrastructure.”
Louise Chapman, NPIF II Fund Principal at Praetura Ventures, noted: “Our NPIF II investment into PEAK:AIO comes at a very opportune time for the AI sector, with Google, Microsoft and Nvidia all announcing plans to invest tens of billions into the UK. Going forward, this news will create even bigger opportunities for companies such as PEAK:AIO.”
Sue Barnard, Senior Investment Manager at the British Business Bank, said: “It’s exciting to see a Northern business at the forefront of the AI sector, developing innovative solutions that advance the technology. This latest round of funding will help create new jobs and scale the business for a successful future.”
