About
Hume AI is an empathic AI company founded in 2021 with the mission of building AI systems that understand and respond to human emotional expression. The company was founded by Alan Cowen, a former Google researcher who pioneered the scientific study of emotional nuance in AI, and is built on the thesis that AI systems capable of perceiving emotional cues will be safer, more useful, and more human-centered than emotionally oblivious alternatives. Hume's research heritage gives it a defensible scientific moat in a space where most competitors treat voice AI as a purely acoustic engineering challenge.\n\nHume's flagship product is EVI (Empathic Voice Interface), a conversational voice AI API that processes not just the words spoken but the emotional tone, prosody, and expression of the speaker to generate more contextually appropriate and emotionally resonant responses. EVI supports 11 languages and is used by developers building voice agents, mental health applications, customer service systems, and AI companions. In 2026, Google DeepMind entered a licensing agreement with Hume to incorporate its emotional intelligence technology — a landmark validation of Hume's foundational research. The developer platform has attracted more than 100,000 users.\n\nHume AI is projecting $100 million in annual revenue and continues to grow its developer base through a combination of API pricing and enterprise agreements. The Google DeepMind licensing deal provides both recurring revenue and industry validation that Hume's emotional AI technology is considered best-in-class by one of the world's most credible AI research organizations. As voice AI proliferates across consumer and enterprise applications, Hume's emotional intelligence layer is increasingly seen as essential infrastructure for building AI experiences that feel natural and trustworthy.
