CertAIn vs Ashby
Ashby is your system of record. CertAIn is your system of judgment.
Ashby is one of the best modern ATSes on the market — the pricing honesty and scale foundations are real. CertAIn isn’t trying to replace it. We’re the reasoning layer on top.
Credit where it's due
Where Ashby is stronger.
- Modern ATS built for scale. Ashby’s data model, reporting surface, and developer API are the best in their class for mid-market and high-growth teams. If a system of record is what you’re choosing, that’s exactly what Ashby is built for.
- Transparent pricing (by ATS standards). Published tiers, per-user pricing, no mandatory multi-year. Closest thing to a kindred spirit in this category on the pricing philosophy.
- Scheduling + analytics depth. Ashby’s built-in scheduling automation and recruiting BI are more mature than most competing ATSes. If you’re bouncing between Calendly, a notetaker, and a BI tool today, Ashby consolidates.
- Foundation for AI. Ashby has been thoughtful about how AI gets added to their product — their sourcing AI and match scoring are real features, not marketing.
Ashby is a strong ATS. This page is for when you already have one and you’re asking what CertAIn adds on top — because we’re not an ATS, we’re the evaluation layer above it.
What Ashby's AI layer isn't
Where CertAIn is stronger.
- A fit score you can defend. Ashby’s AI surfaces a match score with no reasoning attached. CertAIn gives a fit score and the reasoning behind it, per candidate — defensible to a hiring manager, a candidate, or a regulator, and saved to an audit log.
- The four AI actions as a workflow. Ranking, Interview Prep, AI Evaluation, Interview Analysis — a connected decision loop, not four separate features. Workflow gating (Analysis requires Eval first) keeps the quality up at volume.
- Sized to your team, not per-login. Unlimited candidate scoring with the full AI suite included, billed annually — not by user seat. For agencies that bill by the desk, it maps to your P&L better than Ashby’s user-based model.
- Compliance shipped standard. Bias-audit data export, candidate AI disclosure template, architectural human-oversight commitment — shipped on day one, not unlocked per enterprise contract.
- One lane, done well. Ashby is a whole recruiting platform. CertAIn is one thing: making every candidate better evaluated. Narrower scope, sharper output.

You don't choose between them
Migration path
Keep Ashby. CertAIn plugs into your ATS of record via webhook-style flow — candidate and JD data flow into CertAIn for evaluation, reasoning paragraphs flow back as notes on the candidate record. The Greenhouse integration is live now; Ashby is on the roadmap behind it. Until the native Ashby integration lands, CSV import/export works day one for Ashby teams and most start there.
When the fit is sharp
Who should consider CertAIn alongside Ashby
- You’re running Ashby well and your remaining pain is the top-of-funnel triage — reading 500 candidates at depth to pick the right 20
- Your hiring managers want a fit score they can actually defend — the number plus the reasoning behind it, not a number they have to trust on faith
- Your legal or ops team is asking about AEDT, AIVIA, or EU AI Act readiness and wants a vendor with compliance as a default, not as an enterprise conversation
- You’re an agency billing by requisition and per-seat pricing stops mapping to your P&L past a certain team size
