Mike Tung
Mike Tung is the founder and CEO of Diffbot, the company behind the world's largest automated knowledge graph — a continuously-rebuilt database of 10+ billion entities and over a trillion facts extracted from the open web. A UC Berkeley EECS graduate and Stanford AI lab dropout, Tung spent 15+ years building Diffbot with minimal funding (under $15M total) into a platform used by Microsoft Bing, DuckDuckGo, Snapchat, and 400+ enterprises. In January 2025 he launched the Diffbot LLM, an open-source language model grounded in the knowledge graph, achieving top factual accuracy benchmarks among sub-100B models.
