Quick answer: Greenhouse and Ashby for scale-ups that care about process discipline; Workable and Teamtailor for mid-market generalists; Lever for sales-heavy orgs; Workday for large enterprises already in the HCM suite; Recruitee for simple, affordable European teams. AI-Act-ready documentation varies: ask every vendor for a 2026 conformity statement before signing.

1. Greenhouse

The gold standard for process-serious tech scale-ups. Strong structured-interview tooling, excellent reports, mature integrations. Price is higher than mid-market competitors but defensible when hiring is strategic.

Fit: Series B–IPO tech. Watch for: admin complexity, setup time.

2. Ashby

A newer challenger built with modern data modelling. Best-in-class analytics and scheduling. Loved by data-driven talent teams. Rising adoption across European scale-ups in 2025–2026.

Fit: 50–500 person tech companies with in-house TA. Watch for: younger ecosystem, fewer niche integrations.

3. Workable

A broad mid-market ATS popular across the UK and EU. Friendly UI, solid parser, decent price. AI features are reasonable, though the AI Act posture is less explicit than Greenhouse/Ashby as of spring 2026.

Fit: 10–300 person non-tech mid-market. Watch for: advanced reporting is thin.

4. Lever

Historically strong in sales recruiting and outbound sourcing. Clean pipeline UI. Less fashionable than five years ago; still very usable.

Fit: orgs with heavy sourcer-driven pipelines. Watch for: integration breadth vs. Greenhouse.

5. Workday Recruiting

The default choice for large enterprises already running Workday HCM. Powerful, expensive, and politically heavy to change. UX is not its strength.

Fit: 5,000+ employee enterprises. Watch for: implementation cost, candidate-experience pain points.

6. Teamtailor

Swedish-born, strong on employer branding and career-site building. Popular across Nordic and DACH markets. Good for teams that want a beautiful careers page out of the box.

Fit: brand-conscious mid-market. Watch for: structured-interview tooling is lighter than Greenhouse.

7. Recruitee

A solid budget-friendly option for European teams. Clean Kanban pipeline, decent integrations, lightweight analytics. Part of Tellent group.

Fit: 10–200 employees, simple process. Watch for: enterprise-scale limits.

EU AI Act: what to ask every vendor

Do you operate any AI systems on Annex III (employment) of the EU AI Act?
Can you provide the Article 11 technical documentation for high-risk AI features?
What bias-testing have you done? At what frequency? Can we access the report?
Do you log AI-decision events for our tenant (Article 12)?
Can we disable AI-automated-rejection and keep human-final-decision only?
