“Pylon uses AI across our entire product, from agentic workflows for ticket routing to drafting responses to feeding product insights back to engineering. Braintrust gives us logging, evals, a prompt playground, and dataset management out of the box. We now have visibility into how our models are behaving, giving our engineers more time to move our core product forward.”
“Greptile started using Braintrust early in our journey, and it turned out that’s exactly when it mattered most. Being a small team means every hour we spend debugging blind is an hour we’re not shipping. Braintrust gives us visibility into what our models were actually doing, and we can act on it immediately and keep building for our customers.”
