Our Story

From neuro-symbolic research to enterprise infrastructure

Founded in February 2024 by Patrick Joubert and Yann Bilien, Rippletide was born from a conviction: enterprise AI agents need more than large language models. They need a reasoning-first foundation that combines memory, rules, and planning so decisions are deterministic, auditable and far less prone to hallucinations.

Our core technology moves decision-making outside of LLMs (binding facts and provenance with rules and constraints) enabling the deployment of production-grade AI agents for critical enterprise workflows where accuracy is non-negotiable.

The Agent Context Graph (hypergraph)

A new kind of infrastructure that makes AI agents deterministic, explainable, and compliant by design.

Deterministic Reasoning

Decision-making is handled by our rule-based reasoning engine, not probabilistic LLM generation. Actions are selected based on quantitative evaluation against explicit policies.

Full Auditability

Every decision traces back to which data, which rule, which outcome, and why. Policy-as-code enforces guardrails and logs every outcome as a causal trace.

Enterprise Compliance

SOC 2 Type II certified. EU-resident servers. PII stored with end-to-end encryption. Self-service audit log for full transparency and regulatory compliance.

Our Journey

Key milestones on our path to making AI agents trustworthy.
