Crunchbase Company Data API API — Free to Use

Extract Startup Funding Data with the Crunchbase Company Data API

Building a VC research tool? The Crunchbase Company Data API lets you pull real startup funding, investor details, and acquisition history without manually scraping the web.

What You Get

This API aggregates critical startup intelligence:

• Funding rounds — Series A, B, C data with amounts and dates
• Investor profiles — Who backed the company and their investment history
• Acquisition details — Exit data, acquirer info, and deal values
• Company metrics — Employee count, locations, founding date

Perfect for due diligence automation, competitive analysis, or building VC dashboards.

Quick Start: Fetch Company Data

Here's a real example using the main endpoint:

const options = {
  method: 'GET',
  headers: {
    'x-rapidapi-key': 'YOUR_RAPIDAPI_KEY',
    'x-rapidapi-host': 'donnydev.p.rapidapi.com'
  }
};

fetch('https://crunchbase-company-data-api-api-production.up.railway.app/api/company/profile?company=OpenAI', options)
  .then(res => res.json())
  .then(data => {
    console.log('Company:', data.name);
    console.log('Founded:', data.foundedDate);
    console.log('Funding Rounds:', data.fundingRounds);
    console.log('Investors:', data.investors);
  })
  .catch(err => console.error(err));

Replace 'OpenAI' with any company name. The API returns structured JSON with all funding events, key investors, and acquisition data if applicable.

Real-World Use Case

Need to check if a Series B biotech startup raised from Sequoia? One API call gets you:

// Filter funding by investor
const sequia_rounds = data.fundingRounds.filter(round => 
  round.investors.some(inv => inv.name.includes('Sequoia'))
);

No more digging through multiple websites or outdated spreadsheets.
