An AI recruiter that screens candidates by phone

Holds human-like voice screenings with candidates, scores their answers and shortlists talent automatically, so recruiters only talk to the people worth talking to.

How it flows

The problem

Early-stage screening calls ate most of a recruiter's day. The same ten questions, asked hundreds of times, before anyone qualified reached a human.

What I built

  • Conversational voice agents that run natural phone screenings, with custom and cloned voices.
  • LLM evaluation of each transcript against the role's criteria, producing a score and a shortlist.
  • Campaigns for outbound calling, voicemail and SMS, dispatched asynchronously with retries.
  • Admin, demo and affiliate portals, with Stripe billing for self-serve customers.

The result

  • Screening runs around the clock, including outside office hours.
  • Recruiters get a ranked shortlist with transcripts instead of a call list.
  • The platform sells self-serve, with billing and onboarding built in.
