About Backblaze External Website
AI infrastructure runs on data. Storage gets hard at scale. We’ve been breaking, rebuilding, and improving that storage layer for 20 years. We started by building storage servers from scratch in a Palo Alto apartment to save 90% on hardware. Turns out hard constraints make for pretty good engineering. That discipline forged into a platform that performs as well or better than competitors, scales to multi-exabyte workloads, and costs a fraction of what AWS or Google charge. No blank checks or architectural sprawl. Today, the world's leading AI infrastructure providers, neoclouds, and data-intensive businesses run on Backblaze. Our platform includes: - B2 Overdrive: High-throughput object storage engineered for AI infrastructure, GPU workloads, and massive-scale data pipelines. - B2 Neo: White-label enterprise cloud storage powering neocloud platforms for AI, HPC, and media. - B2 Cloud Storage: S3-compatible object storage with predictable pricing, free egress, and no lock-in. - Computer Backup: Automatic, continuous endpoint backup for Macs and PCs. 500,000+ customers. 175 countries.
