We’ve long recognized the transformative potential of AI in security and beyond. Since our founding, SentinelOne has harnessed the power of AI as a force of good – giving organizations the advantage of speed and automation to stop attacks and reduce risk. As the venture arm of SentinelOne, S Ventures’ AI strategy builds on that core DNA and principle, focusing investments on foundational models, platforms, and applications that will shape the future of cybersecurity and protect our collective future. Thus, we’re excited to share the latest example of that strategy by announcing our strategic investment in Galileo, a leading evaluation intelligence platform for AI teams.

AI Safety | Redefining AI Model Evaluation & Security

Building AI applications in today’s rapidly advancing environment requires a new approach to testing and evaluation. As we move deeper into the Generative AI era, tools that help ensure AI models are reliable, accurate, and safe become paramount. Galileo’s platform is redefining how AI teams work, offering a comprehensive solution for developing, testing, monitoring, and securing AI applications, including large language models (LLMs). From evaluating critical factors like hallucinations, coherent AI content that presents false or incorrect information, and agent quality to improving time to production, Galileo’s platform addresses some of the most pressing challenges AI teams face.

Galileo is S Ventures’ latest strategic investment in generative AI-related startups, following similar investments in leading foundational and enterprise LLM platforms such as Anthropic and Cohere. Beyond the platform level, we’ve expanded our AI investment strategy into the development and tooling layer, funding companies like Scale to help operationalize AI at scale. And more recently, we’ve ventured into the Generative AI application layer with an investment in Poolside, an LLM software development co-pilot. With our latest announcement, Galileo represents a critical next step in this strategy, ensuring the models that power these AI applications are secure, trustworthy, and reliable.

Galileo has already seen extraordinary traction, with 834% revenue growth since the start of 2024 and a quadrupling of enterprise customers, including six Fortune 50 companies. The company’s growth underscores the rising demand for solutions that offer transparency and control over AI models. We’re thrilled to participate in Galileo’s latest $45M Series B round alongside Scale Venture Partners, Databricks Ventures, Citi Ventures, ServiceNow Ventures, Amex Ventures, and other top-tier investors.

One of the most significant risks in deploying AI, especially with LLMs, is ensuring that models don’t generate incorrect or harmful outputs. The risk of hallucinations can lead to undesirable outcomes, particularly during mission-critical decision-making and areas like customer service. Galileo’s platform mitigates these risks by providing end-to-end model observability and evaluation capabilities, allowing businesses to spot and correct potential errors in real-time.

This focus on safe, reliable AI directly aligns with SentinelOne’s mission of ensuring security and trust in the digital world. Just as our Purple AI security analyst boosts the productivity of security professionals by automating complex SecOps tasks, Galileo ensures AI models are properly monitored and evaluated so that enterprises can deploy their models with confidence. By providing deep visibility into model behavior, Galileo empowers organizations to optimize their AI applications while minimizing risks.

Why We Invested in Galileo

Founded by AI veterans from Google and Apple, we believe that Galileo is uniquely positioned to lead in the evaluation and observability space. Their platform offers a front-to-back approach, allowing businesses to log model inputs and outputs, and continuously monitor how models perform once deployed in production. This capability is essential as enterprises increasingly move from development to large-scale AI deployments, and it helps maintain AI reliability and safety as models evolve.

SentinelOne believes that security is both a data and intelligence problem, and as AI becomes more prevalent across industries, ensuring that AI systems are safe and secure is an important facet of that belief. Galileo’s solutions are crucial for AI applications across many high-stakes environments. Their ability to reduce risks stemming from hallucinations and agent errors makes certain that businesses can fully leverage the power of AI while maintaining a “first, do no harm” approach.

Conclusion

With this investment, we continue to execute on our strategy of backing category-defining companies across the AI stack from foundational models to cutting-edge applications. Galileo is demonstrating to be an essential part of this ecosystem, and we’re excited to support their journey as they help enterprises build faster, smarter, and safer AI solutions.

We’re proud to welcome Galileo to the S Ventures portfolio, and look forward to working with them as they shape the future of observability and evaluation for AI. Together, we’re committed to fostering a safer, more productive AI-driven world.
