What is this skill?

For founders, investors, and startup researchers, tracking Y Combinator companies and trends is essential. With this skill, your AI can look up YC-backed startups, fetch company profiles, explore batch rosters, and filter companies by industry, tag, or hiring status—all from the public yc-oss API. This makes startup and venture research much faster, whether you're scouting for investment opportunities, job hunting, or analyzing the YC portfolio by sector or diversity.

What you can do

  • Fetch lists of top YC companies, all companies, or those currently hiring ("Show me YC companies hiring now").
  • Look up companies in a specific YC batch ("List all startups from the Winter 2025 batch").
  • Filter YC companies by industry or tag ("Find YC fintech startups" or "Show YC companies tagged AI").
  • Get detailed company profiles and batch metadata for research or outreach.
  • Retrieve diversity lists, non-profits, and overall YC stats for analysis.

How it works

When you ask your AI about YC companies or batches, it queries the yc-oss API using curl to fetch the relevant JSON datasets. The AI then filters and processes the data with jq, returning company lists, profiles, or statistics according to your request. All data is up-to-date and read-only, so you can trust the results for research or reporting.

Good to know

  • Requires curl and jq installed on your system (pre-installed on most macOS/Linux; jq may need to be added).
  • No authentication or API keys needed—the API is public and free.
  • Only works on platforms that allow CLI tools and network access (not Claude.ai web sandbox).
  • Data is refreshed daily but is static—no real-time updates or write actions.
