In their words

Probe is building the agent-native research stack. Our goal is simple: help AI/ML teams run better experiments, faster. We believe research will drive progress and everyone deserves to have their own personalized lab that iterates faster than ever before. Probe brings core research tools, shared context from past experiments, and visibility into each run together in one platform. Helping teams spend less time setting up infrastructure, supervising agents, catching teammates up and more time testing ideas. Built for helping research labs experiment faster while keeping every researcher and agent aligned, and helping AI/ML teams setup a research capability without building a lab’s infrastructure first.
