What is not verified
No revenue figure and no sale price was found. The pages read give a price list and a named pilot, but no page says what any customer paid. That customers pay rests on the company's own terms and pricing page, and no independent source confirms it. A reader could look for the deal terms in a filing or an interview with Greenhouse. This story is grade E: the business is real and its product, price and customers are described from public pages, but no revenue figure was checked. Aiolum shows it as an idea worth studying, not as proof that it makes money.
Ezra AI Labs sold a voice AI interviewer to recruiting teams, and Greenhouse, a hiring software company, bought it in May 2026. The interviewer is a program that talks with each applicant by voice. Before any interview, the recruiter and hiring team define the questions and a rubric. A rubric is a fixed list of criteria used to score every answer for every candidate.
Ophir Samson founded it in 2024, and the a16z Speedrun profile lists 4 employees. The company announced a US$3.2 million seed round on 23 March 2026. Greenhouse announced the purchase on 5 May 2026 and completed it on 27 May 2026. Samson joined Greenhouse as Head of Voice AI, and Ezra stayed on sale as a separate product.
This story has no revenue figure and no sale price, so the evidence grade is E. The pages read show a price list from February 2026 and a named pilot customer, Zapier. They do not show how much any customer paid. Greenhouse's own page says its voice AI is now sold as an annual subscription.

Why did Ezra AI Labs work?
Four causes, in the order they mattered. Each one is a reusable lesson.
It scored every candidate against one rubric fixed beforehand
Greenhouse's release says the recruiter and hiring team define the questions and the rubric before any candidate interview. Every candidate then gets the same role-specific questions and the same rubric, with a full transcript. The Greenhouse chief executive wrote that Ezra is "the first company we've seen that delivers great AI interviews". This is the buyer's own account of why it bought.
Zapier ran a pilot of about 250 interviews and published the results
Zapier wrote that it evaluated several options and that Ezra stood out. Zapier also wrote that Ezra brought it in as a design partner for workflow, ATS integration and scoring. After about 250 interviews, Zapier reported 5 times more candidates screened per role. Only about 5% of Ezra-interviewed candidates were flagged for cheating behavior. These are Zapier's figures, grade C.
It announced a seed round 43 days before the sale was announced
The company announced its US$3.2 million seed round on 23 March 2026, and Greenhouse announced the purchase on 5 May 2026. That is 43 days. The pages read do not say whether the two events are linked.
How it was built
Few build details are public. These come from the company's pages and the buyer's release. [2, 3, 6, 12]
- Before an interview, the product interviews the recruiter and hiring team to set the questions and the rubric for the role. This is stated in the Greenhouse blog of 5 May 2026.
- Each candidate is interviewed by voice and scored against the rubric. The recruiter gets a transcript and an explainable evaluation. This is stated in Greenhouse's release.
- The pricing page lists cheat detection, fraud and deepfake detection, a Slack integration and ATS integration as features. Fraud and deepfake detection is listed only for Enterprise.
- The company's site used the page builder Framer, as the page source of the 10 July 2025 capture shows.
- The pricing page says interviews are recorded only to help the company evaluate a candidate. It also says the data is never sold or used to train AI models. This is the company's statement.
Who tried this before Ezra AI Labs, and why did they fail?
Two companies in our database of failed startups tried to automate hiring with software and shut down. The values below are from that database and are not independently verified.
RoboHR
The promiseAutomate hiring with AI: on-demand sourcing, filtering and interviewing of candidates.
Why it diedThe record names weak product-market fit and weak competitive position, with LinkedIn and Indeed growing stronger.
Gogohire
The promiseA recruiting automation platform for small and medium businesses: sourcing, screening and workflow.
Why it diedThe record names a commoditized feature set and weak differentiation against established players.
The failed startups come from our database of 1,749 dead startups, retold here in our own words. Its entries are AI-assisted summaries of public sources, so these cards carry no evidence grade.
What changed
Both predecessors automated the work around hiring and met large incumbents. Ezra changed one thing: the first interview itself is done by voice and scored against a fixed rubric. Greenhouse says that stage is where volume is highest.
Ezra ended as a feature inside a large hiring platform, not as an independent company. The sources do not say what the buyer paid.
Can one person copy Ezra AI Labs now?
Only the method, and only with a named customer.
The sources show a narrow tool, a published price list and one named enterprise pilot before a sale. They do not show revenue, so they do not show that the business worked on its own. A reader can copy the method of a pilot with a named customer. A reader cannot copy the result, because the price and the revenue are unknown.
Where it is still open: Other first-stage steps with high volume and fixed criteria, where today a person spends minutes on every case.
- 1Pick one stage of a process with high volume, such as the first screen of applicants.
- 2Let the customer define the questions and the scoring rubric for each role.
- 3Run a pilot with one named company and let it publish its own numbers.
- 4Publish a price list, so a buyer can see how the product is sold.
How much did Ezra AI Labs make, and what was it sold for?
Each row shows the evidence grade and the source numbers from the list at the end of this page. The grades are explained in How Aiolum verifies.

How to read this table. A grade A value is stated by the buyer in its own release or blog. A grade C value is stated by the company, by a customer about its own pilot, or by an accelerator profile. No row shows revenue or a sale price.
| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Starter | 250 | 50 interviews a month, 2 recruiter seats | |
| Enterprise | custom | 200+ interviews a month, unlimited recruiter seats, ATS integration |
The page showed two plans and a switch between monthly and yearly billing. It displayed US$250 a month for Starter and no yearly amount, and Enterprise had a custom price. The live pricing page is gone, because ezraailabs.tech and ezrarecruiting.com now lead to Greenhouse.

What could go wrong for Ezra AI Labs?
The risks are the mirror image of the causes above.
What is not verified
No revenue figure and no sale price was found. The pages read give a price list and a named pilot, but no page says what any customer paid. That customers pay rests on the company's own terms and pricing page, and no independent source confirms it. A reader could look for the deal terms in a filing or an interview with Greenhouse.
AI is used to evaluate job applicants
The product scores job applicants and flags cheating. The company's pricing page says Ezra never decides who gets hired and that every candidate can opt out. Greenhouse's blog says candidates always know that AI is involved. Zapier wrote that its invited candidates got a clear explanation and could opt out with no penalty. Greenhouse says Ezra now falls under its monthly independent bias audits. No independent audit of Ezra before the sale was found.
Testimonials, counters and a logo wall rest on the company's pages
The home page shows eight named testimonials with company logos: Mercury, Zapier, Airbnb, OfferFit, Ello, Dandy, Zendrive and Clover Health. Only Zapier's use is confirmed on another page, as a pilot. Several of the other quotations speak of a demonstration or of future use, not of use as a customer. The pricing page states an average candidate rating of 4.8 out of 5 with no number of ratings. The home page counters on applications growth carry no source.
Figures differ between pages, and the team size is undated
The 2025 home page says screening time falls by 90%. The seed release says up to 75% more time saved. The Zapier case-study page says 80%. The a16z profile gives 4 employees without a date. The sale price, the investors' stakes and the terms for the founder are not public in the pages read.
