Greenhouse, a recruiting platform used by more than 7,500 companies, announced it has entered into a definitive agreement to acquire Ezra AI Labs, a voice AI interviewing company focused on structured, on-demand candidate conversations. The acquisition is expected to close this quarter, subject to customary closing conditions.
The deal comes as recruiters face a sharp increase in the number of applications and increased use of AI by job seekers. According to Greenhouse, the number of applications per recruiter on its platform has increased by 412% since 2023, and 74% of candidates are using AI in their job search. The company believes this acquisition will enable recruiters to more effectively identify qualified candidates and provide candidates with a more engaging and transparent hiring experience.
Greenhouse said Ezra AI Labs was designed to address the shortcomings of earlier AI interviewing solutions, which were often criticized for creating an impersonal experience and lacking transparency. The company noted that Ezra’s conversational audio technology allows candidates to participate in natural discussions rather than one-sided video interviews.
The acquisition expands Greenhouse’s structured recruitment methodology into the early stages of hiring, allowing more applicants to participate in interviews and providing recruiters with additional insights beyond resumes. Greenhouse said the technology can provide hiring teams with structured assessments, interview transcripts and competency-based evaluations while maintaining explainability and transparency.
Ezra AI Labs conducts AI-driven audio interviews that can be customized to specific roles and company culture. Candidates are evaluated based on consistent criteria, and recruiters receive structured scores and interview summaries. The platform also allows candidates to ask questions about the role, team, and organization during the interview process.
For recruiters, this technology integrates directly into applicant tracking system workflows, helping organizations screen a larger pool of candidates without extending hiring timelines. The platform also includes features designed to identify AI-generated or scripted responses and provide structured feedback that can support candidate communication.
The system provides candidates with on-demand interviews that can be completed from anywhere and at a convenient time. Candidates can share their experience in their own words, participate in structured interviews related to specific job requirements, and be evaluated based on their responses. Candidates can opt out at any stage.
Greenhouse said Ezra AI Labs will initially be available as a standalone product to both existing and new customers. Over time, the company plans to further integrate Ezra’s technology into broader AI capabilities, including interviewing, talent matching, and candidate experience efforts.
The company also emphasized its focus on privacy, security, and responsible AI governance. Greenhouse maintains ISO 27001, ISO 27701, and ISO 42001 certifications, and says its customers’ personal data is not used to train internal or third-party AI models. The company also conducts independent monthly bias audits of its AI-powered talent matching capabilities.
Main quotation:
“The hiring process today is essentially the same as it was 30 years ago, only moved online. Resumes used to be paper, now they’re PDFs. It’s not transformation, it’s modernization. Even though AI has reshaped many areas of work, AI interviewing has been held back by the technology’s limitations and has been considered clunky, robotic, and unfair. For both candidates and recruiters, AI interviewing has truly realized its potential with Ezra For the first time ever, voice conversations are different: they offer what other categories have promised and failed to do: a better experience for candidates, fairer evaluations, and real signals for recruiters.”
Daniel Chait, Greenhouse CEO and Co-Founder
“Hiring is one of the most important decisions companies make, but the first wave of AI in recruiting made the situation worse, not better. AI magnified bias, hid how decisions were being made, and created an experience that felt rote and unfair. We built Ezra to do the opposite: give every candidate a voice and make better decisions. Voice is important because people reveal so much more in conversations than resumes. With Greenhouse, we can now take that approach to the scale we need to fundamentally improve how recruiting works for everyone. ”
Ophir Samson, Ezra AI Labs CEO, CTO, Founder
“Structured recruitment means that all candidates receive the same fair and consistent evaluation at all times. But until now, we have not been able to apply this principle to the first stage of the process, where the most numerous and strongest candidates are most likely to be overlooked.Ezra Now we can extend that rigor to the front of the funnel. Every conversation is tailored to the role, every evaluation is accountable, and every hiring decision stays with the team. Candidates know that AI is involved, they know what’s being measured, and they get the conversation, not the void. That’s what responsible AI in recruiting looks like.”
Meredith Johnson, Greenhouse Chief Product Officer
