Galileo
AI evaluation and observability platform, now a Cisco business unit inside Splunk.
On the record
Checkpoint: 12-month founder earnout cliff and FY27 Splunk product guidance
The call
Galileo survives as a Cisco unit, but whether it becomes a flagship Splunk feature or a buried checkbox depends on integration choices made in the next year.
Galileo built tools to watch over artificial intelligence applications and catch problems before they hurt users. Cisco bought the company in May 2026 and absorbed it into a bigger Splunk product, which makes Galileo harder to copy in one way (it now has Cisco's resources and sales team behind it) but riskier in another way (large companies sometimes bury small acquisitions and stop improving them). The real question is whether Cisco will treat Galileo as a central piece of its strategy or let it become a forgotten add-on, which depends entirely on whether Splunk sales staff get rewarded for selling it and the original Galileo team stays empowered to build new features over the next year.
Why
01
AI pressure: OpenAI, Anthropic, Google shipping native LLM-as-judge eval APIs. Frontier labs building evaluation directly into their APIs could make standalone scoring tools like Galileo's Luna-2 optional. Could AI do the core job? Only partly.
02
Bigger players: Datadog, Dynatrace, Databricks MLflow, Microsoft Azure AI Foundry. Rival platforms are shipping their own AI agent monitoring, giving Splunk customers reasons to look elsewhere post acquisition. Could a giant copy it? Yes, easily.
03
What protects it. Cisco/Splunk's existing enterprise install base and Luna-2's proprietary small-model scoring baked into that workflow.
What would change this call
Whether Galileo's founders (Chatterji, Sheth, Sanyal) remain at Cisco past the 12-month earnout cliff in mid-2027. Departure would signal Galileo is being absorbed and hollowed out rather than prioritized.
Whether Splunk names Galileo/AI Agent Monitoring a named growth pillar in Cisco or Splunk FY27 investor guidance. Inclusion shows real internal priority; omission suggests it is becoming a bolt-on.
Whether Datadog or Dynatrace announce competing AI-eval suites winning named Splunk customers within 12 months. Would show existing Galileo/Splunk customers defecting to rival observability platforms.

Key numbers
- $68.1M raised before acquisition
- Cisco deal closed May 22, 2026
- ARR grew over 300% YoY in 2025
Named risks
- Galileo becomes an underutilized bolt-on feature inside Splunk rather than a flagship product.
- Founding team departs before 12-month post-close earnout cliff, signaling low integration priority.
- Existing standalone customer contracts and pricing remain unclear post-acquisition.
- Category commoditization from open-source tools and frontier-lab native evaluation bundling.
- Brand dissolution and renaming disrupts existing customer integrations.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Microsoft (Azure AI Foundry, Agent 365) | gaining on | Shipped competing enterprise AI governance tools at Ignite, November 2025 |
| Langfuse | gaining on | Open-source tracing/logging commoditizing Galileo's observability features as of mid-2026 |
| Arize AI | contesting | Actively marketed against Galileo in comparison content as of June 20, 2026 |
| LangSmith | contesting | Named direct competitor in observability comparisons, June 2026 |
| Databricks (MLflow) | gaining on | Platform incumbent shipping overlapping evaluation tooling as of 2026 |
Questions people ask
- Is Galileo still an independent company?
- No. Cisco announced intent to acquire Galileo on April 9, 2026, and the deal closed May 22, 2026. Galileo's technology is now folded into Splunk Observability Cloud as 'AI Agent Monitoring,' making Galileo a Cisco business unit rather than a standalone startup.
- Who owns Galileo now?
- Cisco owns Galileo as of the acquisition closing on May 22, 2026, having announced the deal April 9, 2026 to strengthen Splunk's agentic AI monitoring capabilities. Deal terms and price were not disclosed.
- Is Galileo profitable?
- No profitability figures have been disclosed. Galileo (vendor-claimed) reported 834% revenue growth in 2024 and over 300% ARR growth in 2025, but was acquired by Cisco in May 2026 before any public profitability data emerged.
- Could AI replace Galileo's evaluation platform?
- Partially at risk: Galileo's core LLM-as-judge function could be commoditized if OpenAI, Anthropic, or Google bundle evaluation natively into model APIs. Galileo's defense is its proprietary Luna-2 models (fine-tuned Llama 3B/8B) offering sub-200ms scoring across 100% of traffic as of April 2026.
- Who are Galileo's biggest competitors?
- Named direct competitors include Arize AI, LangSmith, Braintrust, Langfuse, Fiddler AI, Latitude, Patronus AI, TruLens, and Humanloop, per a June 20, 2026 comparison report, alongside platform incumbents like Databricks MLflow and Microsoft Azure AI Foundry.
- How much funding did Galileo raise before being acquired?
- Galileo raised $68.1M total across roughly five rounds as of April 8, 2026, including a $45M Series B in October 2024 led by Scale Venture Partners with Databricks Ventures and Citi Ventures participating, before Cisco's acquisition closed May 22, 2026.
