Why CompanyEnrich

Scale your business, not your data work

Sales calls, raw data dumps, messy formats, and unreliable APIs can turn a simple data need into a full-time job.

✕

Slow sales process

Sales calls, long contracts, and annual minimums that delay your first API call by weeks.

✓

Self-serve from day one

Free signup, instant API keys, transparent pricing, and docs that get you live without talking to sales.

✕

Raw dataset dumps

Massive data files to clean, load, and host across multiple servers, then redo with every new delivery.

✓

Fully managed data infrastructure

900M+ raw records distilled to 33M companies and 204M+ professional profiles, then hosted and refreshed for you.

✕

APIs that break at scale

Slow responses, tight rate limits, and unreliable endpoints that hold back your backfills and your product.

✓

Built to work at scale

Low-latency REST APIs with high rate limits, built for bulk backfills and production traffic.

Messy, inconsistent formats

Free-text fields, mismatched formats, and different schemas that slow down every integration.

✓

Structured data, ready to use

The standard fields you expect, in a consistent JSON schema across company and people data.

Multiple vendors

Enrichment from one tool, people data from another, and lookalikes from a third, each with its own billing and quirks.

✓

A complete API suite

Get company enrichment, search, lookalikes, people search, and reverse email with one key and one credit pool.

✕

Stale, junk records

Credits wasted on parked domains, dead websites, and duplicate entries that pollute your pipeline.

✓

Verified, deduplicated data

Data from the public web, maps, social media, and government records, deduplicated and validated before it reaches your queries.

✕

Agents stuck on web search

Slow tool calls, wasted tokens, and no real filters when your agents crawl the web for answers.

What can I build with CompanyEnrich?

How is CompanyEnrich different from other B2B data providers?

  • Built for moving fast. Sign up, get an API key, and make your first call in minutes, then test and iterate with no sales calls or annual commitment. We work the same way and ship improvements quickly.
  • Every customer matters. At a large provider, you are one account among thousands. With CompanyEnrich, you get support from the engineers who build the API.
  • Verified data quality. Our data quality is tested in public benchmarks, where CompanyEnrich ranks among the top providers.
  • A complete, AI-ready API suite. 25+ endpoints cover enrichment, search, lookalikes, and people data, with semantic search and an MCP server built for agentic workflows.

See how we compare.

How many companies and people does CompanyEnrich cover?
CompanyEnrich covers 33M verified companies and 204M+ professional profiles worldwide, distilled from more than 900M raw records. Coverage spans local small businesses and global enterprises across all industries.
Where does the data come from?
We combine public and partner sources, including business registries, company websites, public filings, maps data, and licensed providers. Records are deduplicated across sources, validated, and enriched before they reach your queries. See how we source and verify data.
How often is the data refreshed?
Data is refreshed on a rolling basis, with around 8,000 new companies added every day. Existing records are re-verified regularly, and profiles include update timestamps so you can see how recent each record is.
How accurate is the data?
Every record goes through deduplication and multi-step validation before it enters the database, including checks on domains, addresses, and social links. In Openbenchmarks' public tests, CompanyEnrich had the highest field coverage of 11 company enrichment APIs (95.5%) and the highest lookalike precision of 10 APIs (91.9% in the top 10 results). See the benchmarks for full results, and test on your own records with the free trial.
Is CompanyEnrich GDPR and CCPA ready?
CompanyEnrich is built with GDPR and CCPA safeguards. We provide a Data Processing Addendum, a public subprocessor list, and opt-out and deletion support for individuals. Data you submit is processed only to provide the service and is not used for model training. See the Trust page for details.
Can I embed CompanyEnrich data directly inside my own SaaS product?
Yes. You can use CompanyEnrich to power features in your product, such as enrichment, search, and recommendations, and show the results to your users inside your application. See how platforms build on CompanyEnrich, or book a demo and we'll set up the right plan for your volume.
Can I store CompanyEnrich data in my own database?
Yes. You can store the data in your own database, modify it, and combine it with your own data.
Do you offer OEM or data licensing partnerships?
Yes. If the data itself is what you deliver to your customers, for example through your own API or as a standalone data product, we set this up through a partnership agreement. Book a demo and we'll work out the right terms for your use case.
How do I integrate CompanyEnrich?
Use our official SDKs for TypeScript and JavaScript, Python, Ruby, and PHP, or call the REST API from any language. You can also connect AI agents through MCP, work from the command line with our CLI, or use our n8n, Clay, and HubSpot integrations. One API key works across every endpoint. See the API documentation to get started.
Can AI agents use CompanyEnrich?
Yes. Agents can call the REST API or connect through the CompanyEnrich MCP server, which works with Claude Desktop, Cursor, VS Code, Raycast, and any other MCP-compatible client. Agents get structured company and people records in a single call, which is faster than web search and uses fewer tokens. The MCP server is free to use and runs on the same API key and credits as the REST API.
Can CompanyEnrich handle high-volume workloads?
Yes. Rate limits scale with your plan, from 30 requests per minute on Starter to 300 on Scale. The Scale plan adds batch requests of up to 50 domains and async jobs of up to 10,000. Every response includes credit and rate limit headers, and higher limits are available on request.
How does pricing work?
Pricing is credit-based. Each plan includes a monthly credit pool that works across all endpoints, and each endpoint uses a set number of credits per call. See pricing for plans and credit costs.
Can I test CompanyEnrich before paying?
Yes. The free trial includes 500 credits, so you can test enrichment, search, lookalikes, and people search on your own records before choosing a plan.
