Karat Tech Stack

Technical hiring platform with AI-native interview methodology and workforce intelligence

Software Development Seattle, Washington 201–500 employees Founded 2014 Privately Held

Karat runs a technical interview and talent evaluation platform backed by 600,000+ assessments. The stack is lean and polyglot (Ruby, Python, React, TypeScript) across AWS/GCP/Azure, with heavy reliance on collaboration tools (Slack, Jira, Confluence, Asana) and assessment infrastructure (HackerRank). Engineering dominance in hiring (22 of 23 open roles) paired with a focus on architectural improvements and technical debt suggests the platform is undergoing a scaling phase; concurrently, internal initiatives centered on reducing hiring bias and improving interview fairness signal a maturation toward standardization.
