Company Overview
About authzed
Authzed (now SpiceDB) is an open-source, Google Zanzibar-inspired authorization service that enables developers to define and evaluate fine-grained permissions at scale, decoupling authorization logic from application code. Founded in 2021 and headquartered in San Francisco, Authzed built SpiceDB — an open-source implementation of Google's Zanzibar authorization system that powers Google Drive, Google Docs, and YouTube's permission systems — making enterprise-grade authorization accessible to development teams without Google-scale infrastructure.
Business Model & Competitive Advantage
The company raised $3.1 million in seed funding and subsequently $10 million in Series A from Amplify Partners and others, building a commercial platform (SpiceDB Cloud and SpiceDB Dedicated) around the open-source core. SpiceDB allows developers to define complex permission schemas (who can view, edit, or delete what under what conditions), evaluate permissions in sub-millisecond latency, and handle the circular dependency challenges that make authorization systems notoriously difficult to build correctly.
Competitive Landscape 2025–2026
In 2025, Authzed/SpiceDB operates at the forefront of the fine-grained authorization (FGA) market, which has grown significantly as enterprises build multi-tenant SaaS products with complex permission models. The company competes with Okta's Fine-Grained Authorization (FGA) product, Auth0's authorization features, and OpenFGA (CNCF project based on SpiceDB concepts). The growing complexity of AI agent permissions — which agents can access which data sources, on behalf of which users — has created new demand for the kind of policy-based authorization SpiceDB provides. Authzed's 2025-2026 focus includes AI-native authorization patterns for agentic systems.
