3i People Tech Stack

AI-powered staffing platform with infrastructure-first engineering

IT Services and IT Consulting Alpharetta, GA 201–500 employees Founded 2002 Privately Held

3i People operates a staffing business backed by Leap Tiger, a proprietary AI-driven applicant tracking system. The tech stack reveals a serious infrastructure organization: Kubernetes, Docker, Terraform, and multi-cloud deployment (AWS + Azure) dominate, paired with event streaming (Kafka, NATS) and CI/CD automation. Active pain points around high-availability platforms, failed job resolution, and scaling suggest Leap Tiger is moving beyond simple ATS into a distributed, high-throughput candidate-matching engine—a shift from traditional staffing tooling.
