What social traction means here
Returner compares observable public signals for YC startups across social, developer, launch, video, community, and web sources. The current snapshot connects 4,685 evidence records to 312 cohort company records; it does not infer private revenue, retention, growth, or investment performance.
How the ranking should be used
Use the ranking to discover companies with visible public momentum, then open each profile to inspect its evidence and coverage. Platform-native signals are normalized by the current documented scoring model; they are not converted with a hand-picked cross-platform exchange rate. Read the full traction score methodology and limitations.
