I'm building a sales enrichment tool and need a company data API

Here are solid options for a company data API for sales enrichment, depending on your budget and the fields you need.

Top API options

• Best if you want fast integration and good coverage

2) Apollo

• Good for: company + contact data for sales prospecting
• Pros: broad B2B database, useful for outreach workflows
• Cons: data quality can vary by region/industry
• Best if you want both company and people enrichment

3) ZoomInfo

• Good for: enterprise-grade sales intelligence
• Pros: large database, advanced filtering, strong sales features

• Best if you need deep B2B data and can handle enterprise pricing

4) People Data Labs

• Good for: developer-friendly enrichment API

• Best if you want to build your own enrichment workflows

5) Crunchbase API

• Good for: company profiles, funding, industry, growth signals
• Pros: great for startup and company intelligence

• Best if your tool needs company discovery and firmographic context

6) FullContact

7) Lusha

What to look for in a company enrichment API

• Firmographics: industry, employee count, revenue, HQ, locations
• Technographics: tools/stack used
• Funding data: round, amount, investors
• Identifiers: domain, LinkedIn URL, company ID
• Coverage: geography and company size
• Freshness: how often data is updated
• Match rate: how reliably a domain or name resolves
• Rate limits and pricing
• Compliance: GDPR/CCPA, data sourcing, opt-out handling

If you want a quick recommendation

• Best all-around for sales enrichment: Clearbit or Apollo
• Best developer-first: People Data Labs
• Best enterprise sales intelligence: ZoomInfo
• Best for company discovery/funding: Crunchbase
