Greenhouse is an applicant tracking system (ATS) and hiring platform founded in 2012 by Daniel Chait and Jon Stross. It is built around the idea of structured hiring: defining role requirements, interview plans and scorecards up front so that hiring decisions across a company are based on consistent, comparable criteria rather than ad hoc interviewer judgment. The platform spans sourcing, candidate relationship management, interview scheduling and evaluation, offer management, onboarding, and reporting.
Greenhouse organizes its product around several pillars: AI-assisted recruiting (including an AI Notetaker that transcribes and maps interview notes to scorecard questions), talent sourcing and CRM tools, structured interviewing with interview kits and scorecards, scalable workflows with automation and governance controls, an onboarding module that carries new-hire data from the ATS into a company's HR systems, and reporting and insights with 40+ pre-built reports plus BI connectors. In 2026 the company added Greenhouse Real Talent, an identity-verification and fraud-detection layer for candidate vetting built with CLEAR, following its acquisition of voice-AI interviewing company Ezra AI Labs.
The company is aimed at organizations ranging from early-stage startups through scaling companies to large enterprises, and lists customers including Anthropic, DoorDash, HelloFresh, Coursera, Okta, HubSpot, Lyft, Betterment, the NFL and MLB. It connects to hundreds of third-party recruiting, HRIS and productivity tools through pre-built integrations and an open API/developer platform.
