# Raindrop

> Raindrop is a San Francisco applied-AI company building the monitoring and observability platform for AI agents - often described as 'Sentry for AI agents.' It traces production agent runs, automatically detects silent failures like hallucinations, loops, and broken tools, and uses small custom models to surface behavioral signals such as user frustration. Founded in 2023 by Zubin Koticha, Alexis Gauba, and Ben Hylak, the company raised a $15M seed round led by Lightspeed in December 2025 and counts Replit, Speak, Clay, Framer, and AngelList among its customers.

- **Notable:** Raised $15M seed led by Lightspeed Venture Partners in December 2025, Backed by founders of Replit, Notion, Framer, Cognition, and Speak, Graduated from Y Combinator (Winter 2024)

## Products & services

- **Issue Detection** — Automatically identifies silent agent failures such as hallucinations, infinite loops, broken tools, and refusals from production traces.
- **Agent Trace Inspection** — Captures every message, tool call, retry, and error from production agent runs for root-cause analysis.
- **Signals** — Small custom classifier models that monitor behaviors like 'User Frustration' or custom-defined signals such as 'Agent Stuck in a Loop' across millions of events.
- **Deep Search** — Semantic search that lets engineers find and track patterns across millions of production AI events.
- **Experiments & Feature Flags** — Agent-native A/B testing to prove fixes work against live production traffic before full rollout.
- **Triage Agent** — Investigate and debug agent incidents directly from Slack.
- **PII Guard** — Server-side redaction of sensitive and personally identifiable information.
- **Workshop** — Open-source local development tool for building and iterating on agents.
