Navan CTO on Building an Agentic AI Platform With ‘Zero Critical Hallucinations’

By PYMNTS | July 2, 2025

When Navan, a business travel and expense management company, set out to build its artificial intelligence-powered virtual travel agent called Ava, it faced the challenge of making sure the system didn’t hallucinate.

In corporate settings, even one AI-generated error — like offering a refund that violates fare rules or showing the wrong flight details — could lead to customer dissatisfaction, financial loss or regulatory penalties.

To overcome that, Navan built Navan Cognition, a platform with multiple layers of agents, AI supervisors, chain-of-thought and reasoning tools, as well as rule-based and large language model-driven assessments. These multiple backstops double-check the responses to a customer’s questions to ensure accuracy.
