DL · Jiawei Li on papers and patents
I'm a full-stack AI builder. For nine years I've taken AI from research to revenue: co-authoring a KDD Best Student Paper, co-inventing seven patent families, and leading products that serve billions of users and move $100M+ in annual ad spend.
I started at Microsoft, first on Bing Ads and then leading AI music creation at XiaoIce, where our model became a $1M+ business and was shown on CCTV. At ByteDance I led AI creative for Ocean Engine's ads business, the 70+ person XR Foundation team behind PICO 4, and a multimodal generation platform serving TikTok, Douyin, CapCut, Jianying, and Doubao.
Today I'm a Partner and Head of AI Product at Tec-Do, where I lead Navos, a multi-agent marketing platform, after building Tec-Creative. I'm also the founder of Adcreafy.ai. My research looks at the same problem from the other side: how agents use tools, coordinate, and get evaluated in production, most recently in Fast Models, Slow Evidence (arXiv, 2026), a paired and self-audited evaluation of fast decision models inside LLM agent harnesses.
