李天天

Li Tiantian is the founder of 丁香园 / DXY in No.206 检索、送药、看病：互联网医疗这些年 | 中国互联网故事22. The episode says he came from a medical family, studied at Harbin Medical University, discovered PubMed while doing academic work, and built an early medical literature search site with self-taught web tools.

The source uses Li as a founder example where the product came from a narrow professional pain point rather than from a top-down internet platform thesis. That makes his path useful for the wiki’s broader distinction between authentic domain demand and generic platform transplantation.
