ycombinator.com/companies is an Algolia index behind a React app. Ours is one server-rendered template. Source Serif 4 italic for the headline, Outfit 200 for everything else, #f5f5ee background, the facet sidebar with counts, the search box, "Showing N of M companies", round logos, orange batch pills.

The companies are the real S26/F26 launches the pipeline pulls from YC. Search and the batch checkboxes are real. The "Apply" button goes to /apply, which is shorter than YC's.
