B2B Sales Intelligence Hub API: Enrich Company Data in Seconds

Prospect research shouldn't take hours. The B2B Sales Intelligence Hub API pulls together funding data, LinkedIn insights, tech stack detection, and contact info into a single enrichment endpoint—perfect for sales teams tired of manual research.

What You Get

This API combines multiple data sources into one request:

Crunchbase funding data – Recent rounds, investors, valuation
LinkedIn company intelligence – Size, industry, employee count
Tech stack detection – What tools and frameworks they're using
Contact discovery – Decision-makers and their info
Company fundamentals – Founded date, location, website metrics

It's designed specifically for B2B sales workflows where you need actionable insights fast.

How to Use It

The main endpoint is straightforward. You pass a domain and specify whether you want contact data:

const domain = 'stripe.com';
const apiKey = 'YOUR_RAPIDAPI_KEY';

fetch(`https://b2b-sales-intelligence-hub-api-production.up.railway.app/api/company/enrich?domain=${domain}&include_contacts=true`, {
  method: 'GET',
  headers: {
    'X-RapidAPI-Key': apiKey,
    'X-RapidAPI-Host': 'b2b-sales-intelligence-hub.p.rapidapi.com'
  }
})
.then(res => res.json())
.then(data => {
  console.log('Company Name:', data.company_name);
  console.log('Founded:', data.founded_year);
  console.log('Tech Stack:', data.tech_stack);
  console.log('Recent Funding:', data.funding_rounds);
  console.log('Contacts:', data.contacts);
})
.catch(err => console.error('Error:', err));

Real-World Example

Imagine you're sourcing leads for a DevOps platform. Query a prospect's domain:

const prospects = ['notion.so', 'figma.com', 'linear.app'];

prospects.forEach(domain => {
  fetch(`https://b2b-sales-intelligence-hub-api-production.up.railway.app/api/company/enrich?domain=${domain}&include_contacts=true`, {
    headers: {
      'X-RapidAPI-Key': process.env.RAPIDAPI_KEY,
      'X-RapidAPI-Host': 'b2b-sales-intelligence-hub.p.rapidapi.com'
    }
  })
  .then(res => res.json())
  .then(data => {
    // Instantly see their tech, recent funding, and key contacts
    console.log(`${data.company_name} uses: ${data.tech_stack.join(', ')}`);
  });
});

The response includes everything you need to personalize outreach—no tab-switching between tools.

Why This Matters

Sales teams typically bounce between Crunchbase, LinkedIn, G2, and Hunter. This API consolidates that research into one call. Fewer tools = faster qualification = more time selling.
