The AI Decisioning Platform that delivers AI-level benefits without the risks.

0% hallucinations. 100% deterministic. Fully auditable.

The AI Trust Gap

Today’s Large Language Models are powerful but flawed: they hallucinate, produce inconsistent outputs and can’t logically explain their answers. Human oversight isn’t an effective safety net, as automation bias guarantees that errors will slip through. In high-stakes sectors, this erodes confidence and blocks adoption.

Rainbird delivers when there is no tolerance for error.

How Rainbird Works

Rainbird transforms your regulations, policies, and human expertise into deterministic world models as knowledge graphs. Our symbolic reasoning engine then reasons over those graphs with complete precision, while LLMs act only as the natural language layer. The result:

Zero hallucinations – Every outcome adheres precisely to your institutional knowledge.

Regulator-ready audit trails – Proof trees show exactly how each decision was logically reasoned.

100% deterministic reasoning – Our symbolic reasoning engine ensures the repeatable precision, traceability, and compliance that human supervision cannot match.

Enterprise-grade scalability – Proven in mission-critical processes across banking, financial services, insurance, tax and more.

This hybrid approach delivers the best of both worlds: the usability of Generative AI with the reliability of logical reasoning.

Global enterprises rely on Rainbird to eliminate risk and accelerate growth:

  • EY used Rainbird to automate its data-privacy checks, turning a process from taking months to minutes, with every result fully explainable and auditable.
  • BDO cut the time needed for R&D tax reviews from five hours to just seconds, helping its advisors take on far more clients while ensuring every decision was consistent and reliable.
  • DACB, a global law firm, used Rainbird to uncover 800% more fraud 500% faster, all with full transparency into how every decision was made.
  • Killik & Co, a financial advisory firm, now completes client suitability checks in a fraction of the time, with every recommendation fully transparent and compliant with financial regulations.

Precise, deterministic and auditable AI is the only way enterprises can deploy at scale. If AI models cannot provide clear justifications for their responses, they will not be trusted for critical tasks. Read more Case Studies.
