Greenhouse Software is an enterprise applicant tracking system (ATS) and end-to-end hiring platform spanning sourcing, structured interviewing, offer management, hiring decisions, and new-hire onboarding. The company markets itself across early-stage, scaling, and enterprise tiers (Core, Plus, Pro) and lists customers including DoorDash, Betterment, MLB, Coupang, HelloFresh, Trivago, and the NFL. Greenhouse exposes a broad developer surface — Harvest (REST), Job Board, Audit Log (Pro), Candidate Ingestion (Partner), Onboarding (GraphQL), Assessment (partner-hosted), and Recruiting / Onboarding Webhooks — that powers hundreds of pre-built integrations across sourcing, assessment, background-check, video-interviewing, HRIS, payroll, SSO, and e-signature vendors. The platform recently acquired Ezra AI Labs to integrate conversational AI into the hiring workflow and continues to invest in fraud detection and identity verification through its Real Talent feature set.
