A Stack Overflow Case Study
Doctolib, a fast‑growing European e‑health service founded in 2013, needed to scale engineering knowledge sharing and onboard hundreds of remote developers across Berlin and Paris during the COVID‑19 pandemic. To avoid interrupting colleagues and to help new hires find experts and understand complex codebases without face‑to‑face contact, Doctolib adopted Stack Overflow for Teams from vendor Stack Overflow.
Using Stack Overflow for Teams as an internal Q&A and searchable knowledge base, Doctolib built a tech community that maps expertise, indexes existing Confluence docs, and encourages asynchronous collaboration and gamified contributions. The deployment scaled from 137 to 300 users, produced knowledge reuse about 14 times a day (400+ times a month), sped up self‑onboarding, reduced interruptions, and improved team cohesion — all enabled by Stack Overflow.
