The post-offer gap is where your program leaks talent.

Most recruiting tools stop the moment a candidate signs. But the offer isn’t the finish line.

Offer accepted Day one
52% Of accepted candidates keep applying to other jobs
2x Renege rates have doubled since 2021
9% Average intern renege rate
7% Average new grad renege rate
$4,700+ Estimated cost of every single renege

Without a purpose-built platform, recruiters manage this gap through personal texts, spreadsheets, and manual emails. It doesn’t scale.

One platform, from accepted offer to converted employee.

Symba picks up exactly where Yello leaves off, carrying the candidate experience through to conversion and onboarding. Most teams stop investing once the offer letter goes out. That’s exactly where reneges, disengagement, and early turnover start. Symba closes that gap.
