Gleen AI is a customer service startup that builds generative AI support agents focused on eliminating hallucinations. Its proprietary machine learning layer sources answers from a company's own knowledge base and documentation, then cross-checks language model responses to ensure accuracy before replying to customers. Originally adopted by technical and crypto communities, Gleen deploys AI agents across help centers, Discord, Slack and web chat to deflect tickets and provide reliable self-service. The company raised a $4.9M seed round led by Slow Ventures with participation from 6th Man Ventures, South Park Commons, Spartan Group and CoinShares, plus notable angels, to expand its generative AI support platform and educate enterprises on accuracy, security and compliance.
