Vertical: Enterprise / HR / ERP (European HRIS for SMB and mid-market). HR and people-ops teams use Personio as the system of record for the entire employee lifecycle: recruiting (job postings to Stepstone/LinkedIn/Indeed, candidate pipelines, interview scheduling, offer letters), onboarding (document collection, e-signature, tasks, equipment), core HRIS (employee profiles, contracts, compensation history, org charts, custom attributes), absence (vacation, sick leave, parental leave with country-specific policies), attendance (timesheets, project time, overtime), performance reviews and goal tracking, payroll (in-house Personio Payroll for DE/UK or sync to DATEV, Lodgic, ADP, etc. elsewhere), document management with GDPR-compliant retention, and workflow automation for joiner/mover/leaver processes.
8/10 within European mid-market HRIS. Personio reports 15,000+ customers, hit $435.6M ARR in 2024 (up from $241.5M in 2023), employs ~2,100 people, and was last valued at $8.5B.

General API rate limit is only 60 requests/minute; auth endpoint is 150/min but drops to 1 req/sec for 60s after a burst. Sudden rate-limit tightening in early 2025 broke production integrations; developers reported 'Too Many Requests' surges with no warning. Full sourced list under Sources below.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
