Turn social graph data into retention

Follower count is the vanity metric. The **business** metric is who engages, who follows whom, and how that changes week over week. Zenndra exposes graph endpoints without headless browsers.

What to measure

  • Follower velocity on creator dashboards
  • Following graph for discovery ("who else do they read?")
  • Fans / clappers on hit articles for outreach lists

Architecture

Snapshot weekly into your warehouse. Join with your product's user ids if writers are also customers. Alert when growth stalls—often a content problem, not a API problem.

Endpoints

  • /user/{user_id}/followers
  • /user/{user_id}/following
  • /article/{article_id}/fans
