Eric Seyoung Jang is the Founder and CEO of DeepBrain AI, a Palo Alto-based company building hyper-realistic AI avatars, video synthesis technology, and conversational AI systems.

Under his leadership, DeepBrain AI raised $44M in Series B funding at a $180M valuation and set its sights on becoming the world's leading generative AI enterprise.
