Greenhouse is the modern structured-hiring applicant tracking system + talent acquisition suite, founded in 2011 in New York City by Daniel Chait (CEO) and Jon Stross (President), both serial founders out of the NYC enterprise-software scene, and built explicitly to operationalize Laszlo Bock-style 'structured hiring' (predefined scorecards, calibrated interview kits, interview-kit-driven evaluation, anti-bias workflow) at SaaS-era scale rather than retrofitting it onto a legacy applicant database.
Vertical: Enterprise / HR / ERP, specifically the applicant tracking / talent acquisition slice (Sanity vertical: Enterprise/HR/ERP; Airtable bucket: misc). Open requisitions, approval workflows, headcount tracking, job templates. Post jobs to a Greenhouse-hosted careers site + syndicate to LinkedIn, Indeed, Glassdoor, ZipRecruiter, Built In, and 200+ job boards.
Very high inside modern tech / SaaS / fintech / consumer internet talent-acquisition stacks; high in mid-market and lower-enterprise overall; the default ATS brand-name reference for 'modern structured-hiring ATS' the way Salesforce is for CRM.
Candidates: deduplicated person records, contact info, source, owner, tags, custom fields, attachments (resumes, cover letters). Applications: the formal application linking a Candidate to a Job, with status, current stage, rejection reason, source, EEO responses, custom fields.
Founded 2011 in NYC, ~14-15 years old as of 2026. Cloud-native multi-tenant SaaS from day one; built on a Ruby on Rails backend with a modern JSON REST API surface and a React-style frontend.
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.
