"Before Galileo, we could go three days before knowing if something bad is happening. With Galileo, we can know
in minutes. Galileo fills in the gaps we had in instrumentation and observability." 

Darrel Cherry

Distinguished Engineer, Clearwater Analytics

"The tools Galileo provides through its platform ensure that people can build the agentic systems they need, scale those systems, and do so in a way that not only improves user experience but also helps grow the companies and brands behind these products."

Mikiko Chandrasekhar
