Large Language Models generate intent. They dont control execution. Rippletide is the decision runtime that sits between your AI agent and production validating, enforcing, and blocking actions before they happen. Not monitoring. Not advisory. Enforceable. The problem: Agents pass evals but fail in production. Decisions cant be reproduced. Security wont let them ship. Rippletide fixes this: - Blocks unsafe actions before execution - Makes every agent decision reproducible and auditable - Enforces structured decision logic at runtime - Model-agnostic. No prompt refactoring required. Built for AI-native companies deploying autonomous agents in production.
