What Underheard is

Underheard is a Swiss company that builds AI voice agents that talk to real people. Companies pay for Underheard. The people it talks to pay nothing.

  • Staffing. Underheard's voice agent calls your applicants and candidates about availability and open shifts, and writes every answer into your ATS. See staffing
  • Market research. Underheard's AI interviewer asks your customers why, out loud, and turns the conversations into one clear report. See market research

Is underheard.app the same company?

No. underheard.app is a separate music discovery service. We do not run it. Any review, safety score or warning about underheard.app is about that service. Our website is underheard.ai.

Underheard called me or sent me a link. Is it real?

Yes, when it comes from a company you already know. Underheard works for that company and never contacts people on its own. A staffing agency uses us to call its own applicants and workers. A company uses us to invite people to an interview through a link.

Everyone in an interview hears at the start that they are talking to an AI. You can stop whenever you like. Email us to delete your interview.

To check a call or a link:

  1. Note which company the call or the link names, and ask that company directly.
  2. Look at the link. Our links end in underheard.ai.
  3. Write to support@underheard.ai with the number or the link. We reply within 24 hours.

Never do this:

  • Never pay anyone to take part.
  • Never give a password, a card number or a bank login on a call or in an interview.

If anyone asks for these in our name, stop there and tell us at support@underheard.ai.
