Case Study: Runtastic achieves streamlined onboarding and cross-team knowledge sharing with Stack Overflow for Teams

Runtastic grows seamlessly from 20 developers to 120 developers, using central collaboration to burst departmental silos

Runtastic, part of the Adidas group and maker of apps used by 142 million fitness enthusiasts, grew from a small startup into a 250-person organization with an engineering team that expanded from 20 to 120 developers. That scale threatened its agile culture: Confluence wikis became bloated and context from Slack was lost, so teams repeatedly answered the same questions. Stack Overflow for Teams was suggested to provide a focused, searchable place for the bite-sized knowledge engineers actually need.

Runtastic rolled out Stack Overflow for Teams across product teams as a searchable Q&A hub integrated with Slack, tags, and wiki indexing, and enforced simple onboarding standards to seed good questions. The Stack Overflow for Teams implementation raised answer quality and preserved institutional context (the “Runtastic lore”), cut a lot of Slack noise, surfaced cross-office technical discussions, and gave leadership clearer visibility into engineering priorities—helping collaboration across Salzburg, Pasching, and Vienna for the 120-person engineering organization.
