Kaizen Labs Tech Stack

Modern software platform replacing legacy systems in US public services

Software Development New York, NY 11–50 employees Privately Held

Kaizen builds software for government agencies—currently live across 50+ agencies in 17 states serving 40M residents. Their stack (React, Next.js, Node.js, PostgreSQL, Datadog, Sentry) is typical for a product-focused SaaS team, but the hiring mix reveals operational scaling: engineering is their largest department, followed by a substantial HR function managing high-volume sourcing and headcount planning. Active projects span financial systems infrastructure, cloud consolidation (adopting Terraform, Docker, Kubernetes), and developer tooling—suggesting they're both scaling operations internally and hardening their platform for enterprise government deployment.

About Kaizen Labs

Kaizen replaces outdated software used by local, state, and federal agencies in domains like recreation, transit, licensing, and payments. The company operates as a platform vendor to the public sector, with 50+ agencies already deployed. Their operational focus spans product development, financial systems and payment infrastructure, and a growing go-to-market function. The 11–50 person headcount places them in the early-scale phase; current priorities include building hiring infrastructure (their HR department is disproportionately large relative to size), consolidating their cloud footprint, and supporting complex on-premises or isolated hosting environments that government agencies require.
