Raindrop launches Simulations as total funding reaches $50 million

Y Combinator says Raindrop has raised a Series A bringing its total funding to $50 million and is launching Raindrop Simulations. It describes Raindrop’s existing service as detecting failed tool calls, hallucinations and problems companies didn’t know to look for in deployed AI agents. Simulations aims to catch failures earlier, during development. Y Combinator names Vercel, Clay, Framer and Speak as Raindrop users.
