Dan Roth

Dan Roth is the co-founder and CEO of Scaled Cognition, a Mountain View AI company building reliable, hallucination-free models for enterprises. Its flagship Agentic Pretrained Transformer (APT) tops agentic benchmarks and powers customer-service agents that follow policy and take action where accuracy matters, such as banking, insurance, and telecom. In June 2026 the company raised a $100 million Series A led by Khosla Ventures at a roughly $750 million valuation. Roth is a repeat founder: he co-founded Semantic Machines, an early conversational-AI company acquired by Microsoft in 2018, where he then served as corporate vice president of conversational AI, and earlier built Voice Signal Technologies, acquired by Nuance.
