Backblaze Announces Five-Year Multi-Exabyte Data Storage Agreement with CoreWeave

$335M Strategic Agreement Aligns to Strong AI Demand and Establishes Backblaze as a Key Storage Provider

Backblaze, Inc. (NASDAQ:BLZE), the cloud storage platform for the AI era, today announced an agreement with CoreWeave, Inc. (NASDAQ:CRWV), The Essential Cloud for AI™.

Under the multi-exabyte, $335 million agreement, Backblaze will provide cost-efficient storage capacity that supports portions of CoreWeave’s managed storage infrastructure, helping optimize placement of data across performance tiers while preserving high-performance storage resources for the demands of AI workloads. The Backblaze technology supports HDD-based storage tiers in CoreWeave AI Object Storage. Customers already utilizing CoreWeave AI Object Storage with its patented LOTA distributed cache will immediately have access to new service tiers without any code modifications.

Every stage of the AI lifecycle depends on the ability to store and move massive volumes of data efficiently. Training, inference, checkpointing, data preparation, model outputs, and retrieval-augmented generation (RAG) all require storage that performs at the speed and scale modern AI demands.

"Storage is the foundation every AI workflow is built on — without it, even the world's most powerful compute sits idle," said Gleb Budman, co-founder and CEO, Backblaze. "We're pleased to work with CoreWeave on elements of their storage environment. This collaboration demonstrates how our platform can help organizations meet growing infrastructure demands."

Backblaze serves more than 100,000 customers worldwide and has extensive experience operating large-scale storage infrastructure. Its cloud platform is designed to deliver reliable, cost-efficient storage services across a range of enterprise and data-intensive use cases.

"Backblaze has built a reputation for making complex, HDD-based storage infrastructure reliable and easy-to-consume at scale. We’re pleased to work with them as we continue expanding our platform and managed service offerings to support AI workloads at scale," said Nick Hoover, Vice President at CoreWeave.
