Greenhouse is where candidates live. CertAIn is how you decide.
CertAIn is the reasoning layer on top of Greenhouse: a fit score with the reasoning behind it, on every candidate already in your pipeline. We’re not trying to replace your system of record. Here’s the honest comparison — and the one pricing chart Greenhouse won’t put on their site.
Where Greenhouse is stronger.
- The system of record. Greenhouse is where your candidates, jobs, interviews, and offers live. Ten-plus years of enterprise trust, deep integrations with everything, structured data model.
- Scorecards and structured interviewing. Greenhouse’s opinionated take on interview kits, scorecards, and offer workflows is the closest thing to an industry standard.
- Compliance and reporting at scale. EEO, OFCCP, audit trail — the enterprise checkbox list is covered.
- Ecosystem. Every HR tool integrates with Greenhouse first. If you’re building a recruiting stack, Greenhouse being in it is the normal starting point.
Greenhouse should stay. If you’re running it, running it well, and deriving value from the ecosystem, there’s no reason to swap.
Where CertAIn is stronger.
- AI reasoning, not AI as a bolt-on. Greenhouse has added AI surfaces — candidate matching, JD assistance — but the AI sits on top of their ATS. CertAIn is the opposite: the product is the reasoning.
- A fit score you can defend. Greenhouse won’t stack-rank 136 applicants for you or give a defensible “why” behind a ranking. CertAIn gives every candidate a fit score and the reasoning behind it.
- Predictable annual pricing, sized to your team. The price you sign is the price you pay — no per-candidate fees, no usage surprises. Greenhouse’s pricing is sales-gated and, like most enterprise ATS contracts, typically carries annual renewal escalators that aren’t visible at sign-time.
- No per-seat tax, unlimited scoring. Score your whole pipeline against every req, as often as you want — the full AI suite included, not metered. Adding the people who actually read candidates doesn’t add to your bill.
- Compliance-first AI architecture. Architectural human-oversight commitment, bias-audit data export, and candidate AI disclosure template, shipped day one — not via custom addendums and manual reporting.
- Four AI actions, not one. Ranking, Interview Prep, AI Evaluation, Interview Analysis — the full decision loop, not just the top-of-funnel match.

The renewal-escalator story
Enterprise ATS contracts commonly carry a year-over-year renewal escalator that’s rarely the first thing a buyer evaluates and almost never on the pricing page. Not a conspiracy — just how enterprise SaaS has priced for a decade. CertAIn is billed annually, sized to your team on the pricing page, with no per-candidate fees and no auto-escalator on renewal. Your price is the price you signed.
Migration path
You don’t. Keep Greenhouse. CertAIn’s live integration pulls candidate + JD data in, runs the AI actions, and pushes reasoning back onto the candidate record as notes or attachments. You never leave Greenhouse to use CertAIn — the #1 reason discovery told us other AI-recruiting tools failed with Greenhouse-native teams.
Who should consider CertAIn alongside Greenhouse
- You run Greenhouse and your top pain is the screen-to-decide gap — the candidates are already in Greenhouse, but reading them at depth and defending the call is on you
- You need stack-ranking with explanations your hiring managers will actually read
- Your legal team is asking about AEDT / AIVIA / EU AI Act and Greenhouse’s standard enterprise contract isn’t specific enough
- You’re tired of AI features bolted onto your ATS that don’t actually explain their output
