Business Model
What each company does and how it makes money
Backblaze is a cloud storage platform that provides businesses and consumers with affordable data backup and storage solutions. It generates revenue primarily through two subscription services: B2 Cloud Storage for developers and businesses (consumption-based IaaS) and Computer Backup for individual users (flat-rate SaaS), with B2 representing its fastest-growing segment. The company's key advantage is its cost-efficient architecture built on commodity hardware, which allows it to offer cloud storage at roughly one-fifth the price of major hyperscalers.
Core Scientific operates large-scale Bitcoin mining facilities and provides colocation hosting services for other miners. It generates revenue primarily from mining Bitcoin for its own account—earning block rewards and transaction fees—and from hosting fees paid by third-party miners who use its infrastructure. The company's competitive advantage lies in its scale, operational expertise, and strategic partnerships with major hardware manufacturers, which provide access to efficient mining equipment.
