Raindrop raises $35M Series A to catch AI agents going rogue

What's the deal? Raindrop, an AI agent monitoring platform, has raised US$22.6M Series A round led by CRV, co-founders Zubin Koticha and Ben Hylak told Axios Pro. The startup builds tools to track how AI agents behave once deployed.

Why now? AI safety is now a central concern for companies rolling out autonomous agents. As Raindrop frames it, no one wants an agent to go rogue.

What's the endgame? The company aims to give enterprises visibility into agent behaviour — spotting errors and unexpected actions before they cause damage. The new capital supports that push.

The signal: The round sits in the 95th percentile among all-time Series A rounds for enterprise software startups in the US, based on a sample of 5,241 deals. That places Raindrop among the larger early-stage bets in the sector, reflecting rising investor appetite for tools that keep AI systems in check.
