Backblaze is a cloud storage company that sells object storage and computer backup services to customers ranging from individual consumers to enterprises and AI companies. Its primary product, B2 Cloud Storage, is a consumption-based IaaS object storage platform where customers store, access, and manage data at scale. Customers use B2 for AI and machine learning data pipelines, media workflows, application storage, and cyber resilience. A key differentiator is free egress up to 3x stored data — directly undercutting hyperscaler pricing — alongside transparent, predictable pricing and S3 API compatibility for multi-cloud use. B2 is priced on a pay-as-you-go or committed contract basis, and Backblaze uses a land-and-expand model as customers grow their data footprint over time. Backblaze also offers B2 Overdrive, a premium high-throughput tier targeting AI workloads, and B2 Neo, a white-label version aimed at neocloud GPU providers that lack their own storage infrastructure. The company's legacy product, Computer Backup, is a flat-rate per-device SaaS subscription for automated cloud backup of laptops and desktops, sold primarily to consumers and SMBs. This product is in gradual decline as consumer behavior shifts. Backblaze operates its own proprietary storage software on commodity hardware, which underpins its ability to price well below hyperscaler rates. The company sells through self-serve, direct enterprise sales, channel partners, and MSPs, and is actively moving upmarket in B2 toward larger enterprise and AI-focused customers.
