What does Harvey use on the backend and infrastructure?
Microsoft Azure, OpenAI models, LLM orchestration. The most important operational pattern is that AI workloads depend on reliable orchestration, inference, evaluation, security, and cost controls.
What does Harvey use on the frontend, data, or GTM tooling?
Document retrieval, Enterprise SSO. Public product surfaces and integrations show where an outside vendor can connect without requiring a full platform replacement.
What Harvey's stack means if you sell to them
The strongest pitch is integration or displacement against a named layer: developer workflow, model serving, security, data governance, observability, support operations, or GTM systems. Because the stack is partly detected, sellers should validate current tooling in discovery and frame the value around measurable reliability, latency, cost, compliance, or workflow speed.
