Raindrop Company Development

Silent Failures Become Test Cases

Raindrop's product connects detection with debugging. It groups traces of problematic agent behavior into issues, then uses replayed production traffic to help teams see whether a proposed code change addresses the pattern they observed.

Raindrop Competitive Landscape

An Incident Workflow for Agent Teams

Traditional infrastructure monitoring is often triggered by an exception or a slow request. Raindrop concentrates on cases where an agent completes the request but gets the work wrong, so the team needs to inspect behavior across traces rather than look for a single failed call.
