Raindrop builds monitoring infrastructure that lets engineering teams discover, track and resolve failures in AI agents, replacing generic metrics with small, adaptive models tailored to each product’s behavior. The platform surfaces signals such as “User Frustration” or custom issues like “Agent Stuck in a Loop,” then issues Sentry-style alerts when incidents spike. Raindrop’s background AI agents also investigate patterns, producing step-by-step explanations of failures. The company serves frontier AI customers processing millions of events per day and offers Raindrop Experiments, an A/B testing toolkit for validating fixes across tools, models or pipelines. Funds will be used to meet growing enterprise demand and entrench the product as the default observability layer for AI agents. Founded by Ben Hylak, Zubin Koticha and Alexis Gauba (previous founders acquired by Coinbase, with Ben formerly at Apple’s Human Interface team), Raindrop is headquartered in San Francisco and positions itself as critical infrastructure for sectors like healthcare and financial services where agent errors can be severe.
