Fake candidate detection

We catch fake candidates before you interview them

Your applicants stay yours. Clera checks each one against hundreds of thousands of profiles it has seen and every fake it has caught, and shows you the evidence before anyone books a call.

What your ATS can't see

One phone number, three names

Fakes rarely apply once. Clera has already seen this number under two other names, so your applicant gets flagged before the first call.

The CV, against the record

A job that started before the company did

Clera lines up every job on the CV against LinkedIn, company filings and the people who worked there. Anything that doesn't fit gets marked, with the reason next to it.

Signals your ATS has never heard of

Fakes get better every month. So do the checks.

Tech that didn't exist yet

LangChain in 2019

Clera checks every tool on the CV against the day it shipped. LangChain came out in October 2022. This CV has it at a job that started almost four years earlier.

Reported by other employers

Caught once, flagged everywhere

When a company reports a fake, Clera flags them on their next application to anyone else.

  1. Series B fintech, NYCreported Jun 12

    A different person showed up on the video call.

  2. 40-person AI startup, SFreported Aug 3

    Same CV under another name, same phone number.

  3. Seed-stage devtools, Berlinreported Sep 20

    Both references led back to one Gmail account.

  4. Your applicant flagged before you open the CV

Deep research

Every flag gets a second look

Before a flag reaches you, Clera searches the open web for anything that backs up or breaks the story.

Why it catches what your ATS misses

Fraud tools inside an ATS only compare your applicants with each other. Clera also knows every fake it has already caught, so you find out before the first call, not after the offer.

Questions about fake candidates

Common enough that Gartner expects 1 in 4 candidate profiles worldwide to be fake by 2028. They cluster on remote engineering roles, where nobody meets in person until the offer.

Contact details shared by applicants under different names, emails that follow a generated pattern, CVs that contradict LinkedIn, LinkedIn profiles that don't exist, reports from other employers, and matches against profiles Clera has already confirmed as fake.

Your ATS can only compare your applicants with each other. Clera compares them with the hundreds of thousands of profiles it has seen and every fake it has already caught, so a repeat fake gets flagged on their first application to you.

No. You see the flag and the evidence behind it, and you decide what happens next.

No. There are no passport uploads and no selfies. The checks run in the background, so good applicants never feel suspected.

Ashby, Workable and Lever. Book a demo and we'll connect yours. On something else? Send applicants over on the call and we'll check them there.

Tell us and we reverse the flag. Every flag comes with its evidence, so a wrong one is easy to spot.
