HighLevel Tech Stack

White-labeled SaaS operating system for agencies combining CRM, marketing automation, and payments.

Software Development Dallas, Texas 1,001–5,000 employees Founded 2018 Privately Held

HighLevel operates a multi-tenant SaaS platform serving 1M+ agencies and businesses with white-label CRM, email, SMS, and funnel-building tools. The tech stack reveals a modern, polyglot backend—Node.js + GraphQL + MongoDB + GCP/AWS—paired with aggressive test automation (Playwright, Cypress, Selenium, k6, Locust, JMeter) and observability (Grafana, Prometheus). Active adoption of Claude and OpenAI alongside test observability systems and an AI agent builder suggests a near-term pivot toward LLM-powered features. Hiring remains engineering-heavy but decelerating, with a sizable product org and visible retention/churn pain—typical for high-touch SaaS hitting scaling inflection.
