Most ATS databases are full of previously-screened candidates who were right, just at the wrong time. Talent rediscovery tools surface them automatically.
Most organizations with any hiring history have an ATS full of candidates who interviewed well but weren't selected — not because they were bad candidates, but because the timing wasn't right, another candidate was slightly stronger, or the role didn't match perfectly. Talent rediscovery tools are built specifically to surface those candidates when a new matching role opens.
Cost per hire from the existing talent pool is often dramatically lower than from external sourcing, since screening has already been done. The challenge most teams face is that the ATS is hard to search effectively — talent rediscovery tools solve that specific problem.
