UK-based AI storage start-up Peak:AIO has secured $6.8 million in its seed funding round.

The round was led by Pembroke VCT, which contributed $5m, while other participants included Praetura Ventures and an unnamed Silicon Valley investor.

Peak:AIO will use the funding to continue investing in AI to “grow its groundbreaking solution for the data storage sector and further expand its global presence.”

According to the start-up’s website, the company offers two products: Peak:Archive, a flash-based data archiving solution, and its AI Data Servers, which it describes as a “software-defined storage platform” that can be deployed on Dell servers to bring the necessary low latency and high bandwidth needed for GPU utilization.

“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,” said Fred Ursell, head of investments at Pembroke Investment Managers. “With a team that has repeatedly scaled and exited category-defining businesses, and early validation from some of the most complex customers in the world, we believe Peak:AIO is positioned to be a critical enabler of the AI revolution.”

Mark Klarzynski, co-founder and CSO of Peak:AIO, added: “We’ve already proven what true AI-first infrastructure can achieve; now we’re scaling that vision. This funding fuels the next phase of Peak:AIO: open, high-performance, and built to outpace legacy at every level. Our upcoming designs are engineered to set a new standard, one that legacy systems simply weren’t built to reach.”

Peak:AIO counts among its existing customers the UK’s NHS, Ministry of Defense, and Gov.uk, as well as several universities. Across the pond, the company’s website says that Los Alamos National Laboratory has deployed its solution. Earlier this year, GPUaaS provider Scan Computers selected Peak:AIO’s storage servers for its Nvidia DGX Blackwell B200 cluster.
