Our take
VAST Data is building what you might call the plumbing for the AI era - a purpose-built data platform that unifies storage, compute, and data services in a single, scalable system. With its disaggregated, shared-everything (DASE) architecture, it allows companies to scale their storage independently from compute, meaning AI workloads can grow without being held back by infrastructure bottlenecks. And their platform delivers flash-speed performance, multi-protocol access, and enterprise-grade reliability, all while keeping costs reasonable.
This architecture is especially relevant now, and the company has recently partnered with GMI Cloud as a key data infrastructure provider for GMI's ambitious new "AI factory" in Taiwan. The data centre is expected to house 7,000 NVIDIA Blackwell GPUS and will lean on VAST's exabyte-scale storage to handle data for model training, inference, and real-time processing.
On top of this, VAST has secured some major partnerships and deals that really position it strongly for the future of AI infrastructure. In November 2025, it struck a $1.17B agreement with CoreWeave, making VAST the primary data foundation for their GPU cloud. It also expanded its collaboration with Google Cloud to offer its AI Operating System as a fully managed service, allowing global data access across on-prem and cloud environments using VAST DataSpace. 2026 saw it complete a $1 billion Series F round that rocketed its valuation to $30 billion. These moves suggest VAST isn't just keeping up with AI demand but shaping the infrastructure that will power the next generation of large-scale, distributed intelligent systems.
