What WhoLayer does, in one minute
WhoLayer tells you who is visiting your website and gives you a verified way to reach them.
Most people who visit a website leave without filling in a form. WhoLayer recognizes some of those visitors and tells you who they are.
Four products, one account
- Visitor ID (B2B): the name, title, LinkedIn, and work email of US visitors, plus the company for everyone else. Sent to Slack, a webhook, or HubSpot.
- Shopper ID (ecommerce): a verified personal email for US shoppers who browse without signing in, sent to Klaviyo.
- Data API and MCP: look up emails, mobiles, and company data from your own code, Clay, or an AI agent.
- Identity Cloud: enterprise identity data by contract, for retailers, publishers, ad tech, and platforms.
How you pay
Everything draws from one credit wallet. One credit buys one identified person or one found email. Company-level visitor ID is free. If we don't find someone, you don't pay. See how credits work.
What we don't do
- We don't identify individual people outside the US.
- We don't scrape LinkedIn.
- We don't return anyone who has opted out.
