Company snapshot — Datadog Inc

DDOG in five paragraphs: what it makes and sells, where it sits in the Closelook stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
Datadog runs an observability and security platform that watches cloud applications from the inside, covering infrastructure and application monitoring, log management, security scanning and incident response. Its tools also extend into large-language-model observability and AI agent tracing, aimed at engineering and security teams running software in the cloud. The company is based in New York and sells to businesses across the United States and abroad.
