Frontier vs. Promethium

Frontier is a browser extension that gives sales reps one-click access to the workflows, AI agents and MCPs their GTM team builds — on any page they're prospecting from. RevOps and GTM Engineers build the plays in Clay and connect their existing stack: Clay MCP, Salesforce MCP and others. Frontier deploys those plays to reps inside the browser, where the contact profile, the company site or the email in front of them is already available as context. No exporting to a spreadsheet, no switching to a separate chat tool, no re-explaining what's already on screen.

Promethium delivers self-service data at AI scale through its revolutionary Instant Data Fabric™ — the first agentic platform purpose-built for modern enterprises. Unlike traditional data architectures that require complex ETL pipelines and data movement, Promethium provides real-time, zero-copy access to distributed data across cloud, on-premises, and SaaS platforms. The platform's 360° Context Engine aggregates technical and business metadata to ensure accurate, contextual responses, while Mantra™, our Data Answer Agent, enables teams to build and share reusable data products instantly.
