What is Oso?
Founded in 2018 by Graham Neray and Sam Scott, Oso addresses the persistent challenge of building custom authorization systems from the ground up. The company offers a dual-product strategy: Oso Cloud, a managed service for centralized policy enforcement, and the Oso Library, which utilizes the proprietary Polar declarative language to embed granular access logic directly into application code. This approach allows developers to decouple authorization from business logic, significantly reducing technical debt and enhancing security posture across microservices and AI agent frameworks. By providing a unified authorization layer, Oso enables organizations to manage complex permission models at scale, ensuring consistent security governance across diverse environments.

Strategic efforts will likely center on developer ecosystem growth and the integration of advanced policy-as-code features to meet the rigorous compliance requirements of global enterprise clients.
