What fields can you append?

Common fields include firmographics like industry and company size, geography, categories, and contact details. Tell us the columns you want filled.

What do you need to start?

A dataset with a reliable matching key such as a company name, domain, or email, plus the list of fields you want added.

How complete will the enrichment be?

Coverage depends on how findable your records are from public sources. We flag any record where a reliable value could not be found rather than guessing.

How much does enrichment cost?

Pricing starts at $149 and scales with record count and the number of fields. Your exact price is shown before you pay.

How long does it take?

Most enrichment jobs are delivered within 2 to 4 days. Your exact delivery time is shown at checkout.

The WhyHire Edge

Appended fields carry a source note, and blanks stay blank when we are not sure.

Each field we add records how it was populated, and any record where a reliable value could not be found is flagged rather than filled with a guess, so you can trust which cells are safe to act on.
