A leading healthcare scale-up faced a 30-day time to hire. Despite a 40+ person HR team, hiring stayed slow because processes were manual: screening each candidate by phone, nudging them through the pipeline, and delivering voice trainings after hire.
Bonsai Labs implemented a Voice AI agent that screens candidates within minutes of their application. Candidates who pass screening are immediately booked for a call with a recruiter. The agent is integrated with the client's ATS, sending back key data including transcripts, summaries, and sentiment analysis.
Bonsai Labs targeted the slowest link in the funnel: the lag between application and first human contact. They built a Voice AI agent that calls or answers applicants within minutes of an application landing, runs a structured screening conversation, and scores the candidate. Qualified candidates are handed straight to a recruiter's calendar, while transcripts, summaries, and sentiment analysis flow back into the ATS so recruiters start each call already briefed. The design mirrors a sales insight — speed-to-lead drives conversion — applied to hiring: reaching candidates within minutes rather than days lifted the rate at which they convert to recruiter calls, compressing overall time-to-hire roughly 5X. Model choice, production status, and the EBITDA figure remain to be confirmed with the partner.
High-volume hiring teams where speed-to-contact drives candidate conversion — healthcare systems, staffing firms, and field-service or hourly employers with large recruiting funnels and an ATS to integrate against.

By attacking the lag between application and first human contact. The experts deployed a voice AI agent that calls applicants within minutes, runs a structured screening conversation, and books qualified candidates straight onto a recruiter's calendar — compressing overall time-to-hire roughly 5X versus the prior 30-day process.
The build combined conversational voice AI with process automation: an agent that phone-screens inbound applicants in real time, scores them, and books recruiter calls automatically. The specific model and vendor have not been disclosed.
Time-to-hire accelerated roughly 5X versus the prior 30-day process, with candidates screened within minutes of applying, which lifted their conversion to recruiter calls. Faster hiring also contributed to an increase in EBITDA (figure to be confirmed).
The build timeline was not disclosed, but the impact is immediate once live: the agent contacts applicants within minutes of an application, so time-to-hire improvements appear as soon as the screening funnel goes into production.
