Getting Started
CompanyEnrich is a real-time B2B data API for enriching companies, finding people, discovering lookalike accounts, resolving emails, and powering AI agents with fresh company intelligence.
Use CompanyEnrich to retrieve verified company and people information for business-to-business (B2B) workflows through a single REST API (application programming interface). Enrich a company by domain or social profile, or search 30M+ companies with 15+ filters. Find similar companies with AI, or resolve a work email to a company and person. Connect AI agents to live data through our Model Context Protocol (MCP) server.
The full API suite
Company Enrichment API. Retrieve a company profile from any company domain, name, or social URL. The API returns industry, size, revenue range, location, technologies, employee count, and 15+ additional fields.
Company Search API. Query 33M+ companies by 15+ criteria including industry, headcount, location, founding year, and tech stack. The API returns results in pages and includes full company enrichment data.
Similar Companies API. Submit one or more company domains and get AI-ranked similar companies that match the target profile. Use these results to expand your ideal customer profile (ICP) and discover your total addressable market (TAM).
People Search API. Search 193M+ verified people profiles by name, title, company, seniority, department, experience, location.
Workforce API. Get current employee counts and historical employee-count trends for any company. Use these trends to identify growth, score accounts, and detect hiring slowdowns or expansions.
Reverse Email Lookup API. Resolve any work email into a matched person and company record.
Bulk Enrichment API. Submit up to 10,000 domains in a single asynchronous job (a task that runs without making you wait for completion). The API returns a job ID immediately and sends a webhook notification when the job completes. Each successfully enriched domain costs one credit.
MCP Server. Connect Claude, Cursor, or any MCP-compatible AI client directly to CompanyEnrich data. See MCP Server setup.

Some of the most common workflows we see:
Customer relationship management (CRM) enrichment. Auto-fill missing company fields when a new lead lands in HubSpot or Salesforce. One call to Reverse Email Lookup gives you the full company record.
Lookalike prospecting. Drop in 50 of your best customers, get back the next 5,000 companies that look like them. Sales and marketing teams use this to expand TAM without buying a separate intent tool.
AI agents. Connect Claude or any MCP-compatible agent to our server to query live company data inside your workflow. You don’t need to write integration code.
Hiring insights. Use the Workforce API to identify companies that expanded their engineering teams by 20% last quarter. Then use the Company Enrichment API to research those companies before you reach out.
Form enrichment. When a prospect submits an email on your pricing page, call Reverse Email Lookup. Route the prospect based on company size or industry before adding them to your CRM.
