crunchbase-advanced-search

Search across all Crunchbase entity types (companies, people, investors, funding rounds, acquisitions, schools, events) with full filter support.

Prerequisites

• Node.js 22+
• If CDP connection fails during auth, launch Chrome yourself with https://www.crunchbase.com as the initial URL (see chrome-cdp agent guidance)
• If Chrome is already running via CDP but no Crunchbase tab is open: node skills/chrome-cdp/scripts/cdp.mjs open https://www.crunchbase.com
• If the user is not logged in to Crunchbase, ask them to log in in the Chrome window, then re-run auth

Setup

node crunchbase-advanced-search.mjs auth

Usage

# Search companies (default fields and sort)
node crunchbase-advanced-search.mjs search companies --count=10

# AI companies founded in the last year
node crunchbase-advanced-search.mjs search companies \
  --query='[{"type":"predicate","field_id":"categories","operator_id":"includes","values":["c4d8caf3-5fe7-359b-f9f2-2d708378e4ee"]},{"type":"predicate","field_id":"founded_on","operator_id":"gte","values":["365 days ago"]}]'

# Series A funding rounds over $10M
node crunchbase-advanced-search.mjs search funding_rounds \
  --query='[{"type":"predicate","field_id":"investment_type","operator_id":"includes","values":["series_a"]},{"type":"predicate","field_id":"money_raised","operator_id":"gte","values":[10000000]}]'

# Search investors
node crunchbase-advanced-search.mjs search investors --count=20

# Paginate using after-id from previous result
node crunchbase-advanced-search.mjs search companies --after-id=<last-uuid>

# List available fields
node crunchbase-advanced-search.mjs fields companies

How it works

1. auth — Extracts cookies from your Chrome Crunchbase tab via CDP
2. search — POSTs to /v4/data/searches/{collection_id} with field_ids, query predicates, and pagination
3. fields — Fetches app metadata from /v4/md/applications/crunchbase to list all queryable fields

Query filter format

Each filter is a predicate object:

{
  "type": "predicate",
  "field_id": "categories",
  "operator_id": "includes",
  "values": ["artificial-intelligence"]
}

Available operators: eq, not_eq, contains, not_contains, gte, lte, gt, lt, between, includes, not_includes, blank, not_blank, starts, domain_eq

Date values support relative expressions: "30 days ago", "90 days ago", "365 days ago", etc.

Data storage

~/.local/share/showrun/data/crunchbase-advanced-search/
├── session.json     Auth cookies
└── cache/           Search result JSON files

Session expiry

Sessions expire after ~24 hours. Re-run auth when you get 401/403 errors.
