What is Galileo AI?
Galileo AI is a ai evaluation and observability company. Galileo provides an AI observability and evaluation engineering platform for teams building GenAI applications and agents.
Galileo provides an AI observability and evaluation engineering platform for teams building GenAI applications and agents. Its Series B announcement named Twilio, Comcast, HP, and ServiceTitan as customers or partners and said revenue had grown 834% since the beginning of 2024. The durable market signal is that Galileo AI sits close to a budget owner: security, AI platform, healthcare operations, engineering, developer productivity, or defense procurement depending on the account.
As of June 2026, the company profile is best read through product adoption, funding stage, leadership, and ecosystem partnerships rather than through public revenue, because most companies in this batch do not disclose ARR. Buyers generally evaluate Galileo AI on deployment risk, integration depth, compliance posture, and measurable operational impact.

How does Galileo AI make money?
Revenue is primarily SaaS subscription and usage-based platform spend tied to evaluation runs, observability, guardrails, monitoring, and enterprise governance.
Revenue is primarily SaaS subscription and usage-based platform spend tied to evaluation runs, observability, guardrails, monitoring, and enterprise governance. Galileo has a public free-start motion and enterprise sales path; production monitoring, eval volume, governance, and support are sold through paid plans and custom enterprise terms.
The commercial motion is enterprise-oriented: buyers pay when the platform becomes part of a production workflow, compliance program, developer process, or operational control plane. Growth is driven by more covered users or assets, deeper integrations, expansion from pilots into production, and higher support or governance requirements.
