Current report
We are a high-performance cloud storage platform that serves as a backbone for data-intensive use cases in artificial intelligence (“AI”) as well as across a broad range of other modern cloud workloads. Our platform is designed to help customers address complex storage needs by providing web-scale Infrastructure-as-a-Service (“IaaS”) that can grow with the largest workloads without sacrificing performance, interoperability, or economics.
Current report
Our mission is to make customers successful by solving their toughest data storage challenges. We aim to achieve this mission through purpose-built software and operational expertise that together enable a cloud storage solution optimized for price-to-performance at scale. By substantially reducing the cost, complexity and frustration of storing, using, and protecting data, we empower customers to focus on their core business operations. Customers use us to support AI workflows, help ensure the cyber-resilience of their organizations, streamline media workflows, and enable a variety of other data-focused application and information technology needs. More recently, some companies, especially neoclouds, have integrated Backblaze to offer or enhance cloud storage for their customers. They chose Backblaze for our software and operational experience that together provide a capacity tier of storage that can scale with business' growth without sacrificing performance or economics. Through these companies, Backblaze is supporting the storage needs of the global data center and compute infrastructure buildout the industry is experiencing today.
Current report
In June 2026, we entered into a multi-year Master Strategic Agreement with CoreWeave, Inc. (“CoreWeave”), a leading AI cloud platform provider, under which we will provide committed B2 Cloud Storage capacity and managed storage services on CoreWeave’s infrastructure (the “CoreWeave Agreement”). The two initial order forms under the agreement have terms of five and seven years, respectively, and an aggregate estimated total contract value of approximately $335.1 million, less approximately $21.7 million attributable to the fair value of warrants issued to the customer. We view this agreement as a significant example of the value Backblaze provides to neoclouds and in the AI infrastructure ecosystem.
Current report
May 2026 Price Increase
Current report
Effective May 1, 2026, we implemented changes to the pricing of our B2 Cloud Storage offering, including an increase in the pay-as-you-go storage rate from $6.00 to $6.95 per terabyte per month and the elimination of API transaction fees.

Expansion into AI and Neocloud Ecosystems
Current report
B2 Neo, our white-label, cloud object storage solution, is designed to serve neocloud platforms, which deliver GPU and other compute capacity to their end users. B2 Neo enables these platforms to offer native, branded object-storage as a new service to their end customers. The neocloud market is projected to grow from $35 billion this year to over $236 billion by 2031, driven almost entirely by demand for AI compute. As enterprise customers increasingly seek full-stack cloud platforms rather than raw GPU capacity alone, object storage is a critical data foundation these enterprise customers require. While some neoclouds have some level of object storage offering today, B2 Neo provides neoclouds with a scalable capacity storage tier, where data from a flash tier (the low latency tier that GPUs require to function at optimal levels) can be moved when it’s not being utilized in an active model training run. What differentiates B2 Neo in the space is its ability to scale without sacrificing performance or economics. The value this provides these companies includes more functional capacity in the flash tier, better margins for their storage products, and a solution that can be operationalized now, rather than spending years developing those capabilities in-house.
Current report
AI-native developers and startups
Current report
Beyond these developers and startups new and evolving businesses are establishing themselves in the multimodal generative AI space, including video and audio applications, and selecting B2 Cloud Storage as their object storage tier. These companies gather data for their own use or for sale; process and prepare the data to train their own or third-party models; develop or enhance proprietary models, and provide their models to companies that use them to generate additional data. At every stage, these companies need scalable, high-performance object storage with predictable economics. We have engaged companies like these through our traditional go-to-market activities, but we increasingly see their decision-makers bypass traditional sales and acquisition channels and opt to evaluate our technology directly before engaging with our team.
Current report
This trend also informs our strategy for serving and attracting the next generation of developers. Our new AI developer team, which comprises AI-native engineers and product leaders within our Research and Development organization, is focused on incorporating B2 Cloud Storage into the tooling, documentation, and sample applications that AI developers use to evaluate and deploy new solutions, particularly generative AI applications. Developers increasingly use AI coding agents to assist in building applications that rely on foundational services, including storage. By integrating B2 Cloud Storage with open-source projects, our AI developer team is working to position our platform as a default selection for generative AI projects.
Current report
We expect our go-to-market transformation and recently entered customer contracts to support continued growth in B2 Cloud Storage revenue over time. The pace and magnitude of this growth will depend on the execution of our go-to-market initiatives, customer deployment schedules and usage levels, and the commencement of contracted services.
Current report
We recently began offering committed storage capacity and managed storage services. Under committed-capacity arrangements, the provision of reserved storage capacity over the contractual term represents a single performance obligation that is satisfied over time as the capacity is made available to the customer. Revenue is recognized under these arrangements using an output method based on the proportion of contracted storage capacity made available, which reflects the transfer of services to the customer. Under managed storage arrangements, the related managed storage services generally represent a single performance obligation that is satisfied over time, with revenue recognition commencing when the applicable storage capacity is deployed and the related services become available to the customer.
Current report
Revenue recognition under these arrangements is expected to begin during the third quarter of 2026. Therefore, no related revenue was recognized during the three and six months ended June 30, 2026.

Previous wording
We plan to continue investing in our infrastructure to support the growth of our business. These investments include the purchase and expansion of infrastructure equipment (and related depreciation) as well as software development activities and associated amortization. Because these costs are often incurred ahead of revenue generation, delays in realizing anticipated revenue or fluctuations in the timing of revenue could adversely affect our gross margin from period to period.
Current wording
We plan to continue investing in our infrastructure to support the growth of our business. These investments include the purchase and expansion of infrastructure equipment (and related depreciation) as well as software development activities and associated amortization. These investments may also be affected by higher equipment prices and supply chain constraints, which could adversely affect our gross margin. Because these costs are often incurred ahead of revenue generation, delays in realizing anticipated revenue or fluctuations in the timing of revenue could adversely affect our gross margin from period to period.
