YC Atlas

Interactive dashboard for exploring 5,800+ Y Combinator companies across 46 batches (S05–P26).

Overview: The 21-year YC story at a glance: cohort outcomes, growth trajectory, industry composition, the AI inflection point, and the language each new cohort introduces.
Globe: Every YC company plotted on a 3D globe by city, country, or region. Sized by team, colored by status (Active, Acquired, Inactive, Public). Spot the geographic shifts across 46 batches.
Timeline: Eight metrics traced batch-by-batch across 21 years (S05–P26): status outcomes, stage mix, top-company rate, industry composition, US vs international, team size, country diversity.
Compare: Side-by-side cohort analysis through four lenses: outcomes, industries, regions, and trending themes. Quantify how each new YC batch differs from the last.
Buzzwords: Track phrase prevalence in YC pitches across every batch. Add custom phrases or surface the words disproportionately common in the latest cohort versus all prior batches.
Wall: Browse every YC company in a sortable grid. Filter by status, batch, industry, region, stage, tags, team size, and hiring. Sort by top-company flag, team size, batch, or status.
Heatmap: Cross-tabulate YC cohorts by industry, subindustry, tag, or region. Top 20 categories × 46 batches reveal which themes dominated each season.
Boards: All-time YC leaderboards: highest top-company rate (mature batches), largest teams, most active regions, and public exits — plus the latest batch's tag cloud.
