The difference

“Clay enriches the people you already know about. WhoEngine finds the people you do not know about yet.”

Clay is a workflow tool that starts with a list. You upload a CSV, pull from your CRM, or connect a data source, and Clay enriches each row with additional information from its network of providers. Its value is automation and data coverage: rather than manually researching each person, Clay can fill in company size, LinkedIn URL, recent news, email address, and dozens of other fields automatically.

WhoEngine starts from a description, not a list. You describe your ideal customer, hire, or collaborator in plain English, and WhoEngine discovers who those people are by searching the live public web. You do not need a starting list. You need a starting idea of who you are looking for.

The two tools occupy different steps in the same workflow. WhoEngine is the discovery step: who should be on my list? Clay is the enrichment step: what do I know about the people on my list? Many teams that use WhoEngine for discovery feed the results into Clay for enrichment before routing to their sales engagement tool.

The skill requirements are also different. Clay is a powerful tool that rewards technical comfort with waterfall logic, conditional fields, and API integrations. WhoEngine is designed to feel like describing your ideal person to a researcher who already knows what signals to look for.

When to use which

Different tools for different jobs.

Use WhoEngine when

  • You need to discover who belongs on a list before you can enrich anything
  • You do not have a starting list and are beginning from a plain English ICP description
  • You want to find passive candidates or people not easily found through database filters
  • You need a curated shortlist with cited reasoning, not a spreadsheet of enriched rows

Use Clay when

  • You already have a list of people or companies and need to enrich it
  • You want to automate data pipelines that pull from multiple enrichment providers
  • You are building a custom GTM workflow with conditional logic and CRM integration
  • Your team needs a collaborative spreadsheet-like tool for managing enriched contact data

Common questions

WhoEngine vs Clay: FAQ.

Is WhoEngine an alternative to Clay?

WhoEngine and Clay are complementary tools that cover different steps. WhoEngine is for discovery: finding who the right people are when you start with a description rather than a list. Clay is for enrichment: adding data to a list you already have. A common workflow is to use WhoEngine to identify the right people, then enrich those results in Clay before routing to a sales engagement or recruiting tool.

Can WhoEngine replace Clay for enrichment?

WhoEngine is not an enrichment tool. It does not build waterfalls across multiple data providers or integrate with 50+ sources for automated field filling. WhoEngine finds and ranks people by public signal quality and provides their core contact details. For deep enrichment automation, Clay remains the right tool for that specific job.

Does Clay have a search feature like WhoEngine?

Clay has an AI research agent that can search the web for information about people and companies on an existing list. It does not have a plain English people search that discovers new people from a description. That discovery capability is what WhoEngine provides.
