Y Combinator-backed Raindrop is Building the Monitoring Platform for AI Agents

Raindrop, Sentry for AI Agents, led by Zubin Singh Koticha, Alexis Gauba, and Ben Hylak, has secured $15M in seed funding from Lightspeed and leading AI companies, including Figma Ventures, Vercel Ventures, founders of Replit (Amjad Masad and Michele Catasta), Cognition (Walden Yan), Framer (Koen Bok and Jorn van Dijk), Speak (Andrew Hsu), Notion (Akshay Kothari), and YC.

Over the past two years, the landscape has shifted from simple chatbots to agent systems capable of using thousands of tools and running autonomously for hours. Traditional AI evaluations were built for the chatbot era and no longer reflect how modern agents operate. They fail to measure real-world performance, reliability, or the ability to complete complex, multi-step tasks.

Raindrop is the monitoring platform built for AI agents.

The platform includes:

• The first automatic issue-detection system designed to catch silent agent failures

• The most advanced search system for AI production data

• The first agent-native A/B testing platform

Raindrop is already used by some of the fastest-growing AI companies, including Replit, Speak, Clay, Framer, Tolan, Avoca, AngelList, and others.

Raindrop is built with world-class safeguards and advanced privacy controls to protect sensitive data.

PII Guard - Customizable PII redaction preserves operational visibility while maintaining strict privacy. AI models automatically remove personally identifiable information before data reaches Raindrop’s servers, ensuring sensitive customer details remain fully under client control.

SOC 2 Compliant - Raindrop is SOC 2 Type II compliant, meeting rigorous standards for security, availability, and confidentiality. This certification demonstrates a verified commitment to maintaining the highest levels of data protection.
