PEAK:AIO, the data infrastructure company redefining AI-first data acceleration, has raised £5m in seed funding led by Pembroke VCT, with participation from Praetura Ventures and a Silicon Valley investor. The company will use the funding to expand its global presence and continue investing in its AI-driven data storage platform.
PEAK:AIO has won industry attention by tackling one of AI’s most urgent challenges: data acceleration. Its platform has set records for delivering low-latency, high-efficiency performance across multiple AI verticals, from edge inference to large-scale model training. This advantage has made PEAK:AIO the infrastructure of choice for AI teams where bottlenecks and downtime are not an option.
The new funding marks a step change for PEAK:AIO as it shifts from single-node performance to building scaled-out, AI-native infrastructure. The company is accelerating delivery of its breakthrough pNFS platform, kvcache and AI-focused S3, while embracing emerging architectures such as CXL. Alongside this technical roadmap, PEAK:AIO plans to expand its international footprint through strategic partnerships and on-the-ground deployments.
Backed by investors with deep experience in scaling technology companies, PEAK:AIO’s approach positions it as a critical enabler of the AI revolution. With demand growing rapidly and global technology giants committing significant capital to AI infrastructure in the UK, the company is set to build on its early traction and shape the future of AI-first data systems.
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. 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.
