When WhoLayer is not a fit

You need person-level identification of visitors outside the US. WhoLayer identifies people for US traffic only; elsewhere it's company-level, after consent.
You want a full ABM advertising suite, an on-site AI chat agent, or a built-in sequencer and dialer. WhoLayer identifies and enriches; it doesn't run ads, chat, or send email for you.

The quickest way to know is to try it on your own traffic. The Free plan includes company-level identification and monthly credits, no card needed.
