Plurai raises $13 million for AI agent simulation platform

Nov 11, 2026
Plurai raised $13 million in seed funding and opened its AI agent simulation platform to all developers. The platform tests agents in simulated environments and creates small language models for production use.

Plurai raised $13 million in seed funding and made its AI agent simulation platform generally available, the company said in a press release. Team8 led the round, with participation from U&I, Velocity, Mercer and more than 20 angel investors.

The platform creates a digital twin of an AI agent and its operating environment using a customer's knowledge base, tools and policies. It runs simulated users against the agent to identify hallucinations, policy violations, failed tasks, broken tool calls and sensitive data leaks.

Plurai also uses simulation data to create small language models tailored to specific agent tasks. These models can run agents or evaluate their actions in production. The platform includes a free tier and supports tools such as Claude Code, Codex, GitHub Copilot and Salesforce Agentforce.

Plurai says the platform cut design partners' agent development cycles from months to hours, reduced failures reaching real users by 82% and lowered running costs by 97%. These figures come from the company and have not been independently verified.
