What Galileo does
Galileo is an AI evaluation and observability platform that helps enterprise AI/ML teams develop, test, monitor, and secure LLM-based applications and multi-agent systems. Founded in 2021 in San Francisco by Vikram Chatterji, Atindriyo Sanyal, and Yash Sheth — alumni of Google AI (BERT), Uber AI, Apple Siri, and Google speech recognition — the company has built an end-to-end platform that unifies offline evaluation, production observability, and real-time guardrails into a single "eval-to-guardrail" lifecycle. Core products include Galileo Evaluate (development-time testing), Galileo Observe (production observability with Graph/Timeline/Conversation views), Galileo Protect (real-time hallucination and prompt-injection firewall), Galileo Signals (proactive failure-pattern detection on 100% of traces), and the Galileo Agent Reliability Platform with its Graph Engine and Insights Engine. Underlying proprietary technology comprises the Luna-2 family of small language models (3B and 8B) delivering sub-200ms latency at ~97% lower cost than GPT-style judges, the ChainPoll hallucination-detection methodology presented at COLING 2025, and the Data Error Potential scoring algorithm for training-data quality assessment.
Galileo monetizes through a tiered SaaS subscription (Free at $0/month with 5,000 traces, Pro at $100/month with 50,000 traces, and quote-based Enterprise with unlimited traces), supplemented by usage-based trace overages, AWS Marketplace channel sales, and deployment options spanning hosted SaaS, Virtual Private Cloud, and on-premises. The go-to-market is a hybrid product-led growth motion — anchored on a free tier, an open-source Apache 2.0 Agent Control control plane, and a Hugging Face Agent Leaderboard — combined with a high-touch enterprise sales motion that has landed six Fortune 50 customers plus named logos including HP, Writer, Clearwater Analytics (managing $6.4T+ AUM), Satisfi Labs, Ema, and Magid. Customers span entertainment/venues, CPG, education, financial services, media, and enterprise AI platforms. Distribution is increasingly ecosystem-led through NVIDIA NeMo, Cisco AI Defense, MongoDB, Elastic, CrewAI, Strands Agents, Glean, HP AI Studio, and Cloudera. Following Cisco's April 2026 announcement of intent to acquire Galileo for integration into the Splunk Observability Cloud portfolio, the company operates as a subsidiary within Cisco with closing expected in Cisco's fiscal Q4 2026.

Product offeringCore offering
Galileo provides an end-to-end AI evaluation and observability platform that enables enterprises to build, evaluate, monitor, and protect LLM-powered applications and AI agents at production scale. Its proprietary Luna-2 small language models power real-time guardrails and offline evals at ~97% lower cost than GPT-style judges, while the platform spans development-time evaluation (Evaluate), production observability (Observe), real-time threat and hallucination protection (Protect), proactive failure detection (Signals), and a multi-agent reliability platform with Graph Engine and Insights Engine. Customers include six Fortune 50 enterprises across entertainment, CPG, education, financial services, and customer engagement sectors.
Product overview
Galileo offers an end-to-end AI Reliability Platform that brings together several integrated products and modules to take AI systems from offline testing to production guardrails. The core Galileo Platform is composed of Galileo Evaluate (development-time AI evaluation), Galileo Observe (production AI observability), and Galileo Protect (real-time hallucination and threat firewall). Building on top of this are Luna-2 (proprietary small language models powering always-on evaluations), Galileo Signals (proactive failure pattern detection), the Galileo Agent Reliability Platform (with its Graph Engine and Insights Engine for multi-agent workflows), and the open source Agent Control plane for centralized AI agent governance. Supporting assets include the ChainPoll hallucination detection methodology, the Data Error Potential (DEP) data quality score, the Agent Leaderboard on Hugging Face, and Galileo SDKs in Python and TypeScript, all packaged under the Eval Engineering methodology.
