graph8, founded by Thomas Cornelius, is an AI-first, API-first GTM operating system that processes over 50 billion intent signals monthly and maintains a vast database of U.S. B2B contacts. The system integrates various functionalities such as outbound, inbound, enrichment, sequencing, analytics, email, dialer, and voice AI into a cohesive multi-app ecosystem. To address identity management challenges, graph8 adopted PropelAuth, an identity provider designed for real SaaS architectures, seamlessly facilitating multi-app, multi-org identity integration. PropelAuth was chosen over other providers like Auth0, Clerk, and Stytch due to its robust features such as backend token validation, organization and user claims, cross-app session portability, and its stable SDKs for Python and JavaScript. The implementation of PropelAuth enabled graph8 to achieve significant operational efficiencies, including increased platform velocity, reduced architectural overhead, and freed engineering resources, allowing the team to focus on advanced AI and ecosystem consistency. This strategic move eliminated previous identity-related complexities and inconsistencies, setting the foundation for graph8's expansion as a comprehensive GTM operating system.
