Quickstart

Investors, portfolios, co-investors, companies and new funds as JSON. Every link carries its evidence and the date it was last checked.

1. Your API key

Free accounts get 100 calls a month with a work email and no card. We email a link, and your key appears when you open it. It is shown once, so save it.

Already have one? Log in and this step shows your key's status.

2. Make a call

Ask for the firms that share the most portfolio companies with Sequoia Capital.

curl "https://api.vcinfo.io/v1/firms/sequoiacap.com/coinvestors" \
  -H "X-API-Key: $VCINFO_KEY"

const res = await fetch("https://api.vcinfo.io/v1/firms/sequoiacap.com/coinvestors", {
  headers: { "X-API-Key": process.env.VCINFO_KEY },
});
const data = await res.json();

import os, requests

res = requests.get(
    "https://api.vcinfo.io/v1/firms/sequoiacap.com/coinvestors",
    headers={"X-API-Key": os.environ["VCINFO_KEY"]},
)
res.raise_for_status()
data = res.json()

{
  "firm": {
    "slug": "sequoia-capital",
    "name": "Sequoia Capital"
  },
  "coinvestors": [
    {
      "slug": "sv-angel",
      "name": "SV Angel",
      "domain": "svangel.com",
      "shared_companies": 42
    },
    {
      "slug": "kleiner-perkins",
      "name": "Kleiner Perkins",
      "domain": "kleinerperkins.com",
      "shared_companies": 34
    }
  ]
}

shared_companies counts companies both firms list and that passed their checks. Firms are named by slug, which works anywhere a firm is asked for, as does any domain the firm has used.
