Arize AI Tech Stack

AI engineering platform for agent development, observability, and evaluation

Software Development San Francisco, CA 51–200 employees Privately Held

Arize AI builds a full-stack engineering platform for shipping LLM agents and applications, with a tech stack spanning orchestration (LangChain, LangGraph, CrewAI), model providers (OpenAI, Anthropic), and observability (OpenTelemetry, their own Arize Phoenix). Heavy hiring across engineering and sales—with 36 roles posted in the last 30 days—signals aggressive go-to-market expansion. The pain-point backlog (monitoring, troubleshooting, and scaling observability) aligns directly with their platform positioning: teams struggle to instrument and debug agent systems in production.
