Where they pull apart

Classet

Stands out: Speed to first conversation: candidates get a call or text within seconds of applying, including the many who apply after hours, and the vendor reports about half of interviews happen outside business hours. Flex also bundles job board distribution and ad spend, so a small team can run it with no ATS at all.

Watch out: The ATS-connected plan starts at $1,995/mo and is scoped on a sales call, so integration costs well above the $190 Flex entry price. Flex is billed per job, which adds up quickly across many open roles, and interviews beyond 50 per job a month cost $4 each.

Not the right fit for

  • Agencies filling a few specialist roles at a time
  • Budget teams with many open roles on per-job pricing

Underheard

Stands out: It covers the whole temp worker loop, not just the first screen: instant calls to new applicants, AI matching and SMS outreach when a job order lands, check-ins and compliance reminders on assignment, and an AI receptionist for call-offs, timesheet and payroll questions that hands off to a recruiter. Conversation data is stored in the EU, and calls run in English, German, French, Spanish, Italian, Portuguese and Turkish.

Watch out: Underheard was founded in 2026 and its published customer list is short, so ask for staffing references. No price is published, so budget from a demo quote. The company also sells AI market research interviews, so staffing is one of two product lines.

Not the right fit for

  • Corporate teams hiring a few salaried roles
  • Buyers who want a published self-serve price
  • Executive search firms
