Plurai raises $13 million and opens agent simulation platform
Plurai has made its AI-agent simulation platform generally available with a free tier after raising $13 million in seed funding. The company says its design partners reduced failures reaching users by 82%.
Developers can now use Plurai’s AI-agent simulation platform, previously restricted to selected partners and customers, with a free tier available. The company announced $13 million in seed funding alongside the platform’s general availability.
Plurai says its design partners reduced failures reaching real users by 82% and lowered the cost of running reliable agents by 97%. Their agent development cycles also fell from months to hours, the company says.
Testing an agent’s environment
The platform creates a digital twin of an agent and its surroundings using the customer’s knowledge base, tools and policies. According to Plurai, it then runs thousands of realistic and adversarial users against the agent in a sandbox to uncover problems. Those include policy violations, hallucinations, incorrect actions, broken tool calls, failed tasks and sensitive-data leaks.
Plurai says it generates fixes for failures and uses simulation data to create small language models tailored to each agent. In production, those models can replace larger frontier models that run an agent, or act as evaluators and guardrails checking actions against company policies. Newly detected failures feed back into the simulation.
Developers can start from tools including Claude Code, Codex and GitHub Copilot. Teams can also simulate and improve agents built on enterprise platforms such as Salesforce Agentforce.
Reported customer results
In work with NVIDIA and Nebius for a global enterprise customer, Plurai says its post-trained models outperformed OpenAI and Anthropic frontier models on accuracy at 40 times and 44 times lower cost, respectively. The comparison is a company-reported result for that customer.
The company says it works with enterprises in AI-native and highly regulated industries, including Fortune 500 and major financial companies. It was named a representative vendor in Gartner’s 2026 Market Guide for AI Evaluation and Observability Platforms.
Backers and research
Team8 led the seed round, with participation from U&I, Velocity and Mercer. More than 20 angel investors and industry leaders also backed the round, including CyberArk founder Udi Mokady. Dr. Eyal Carmi, Microsoft 365 Copilot’s chief technology officer, has joined Plurai’s advisory board.
The company was founded by Dr. Ilan Kadar, its CEO, and Dr. Elad Levi, its CTO. Kadar was previously VP of AI at Nexar, where Levi was an AI architect; the pair worked on systems for autonomous-driving companies.
The company says its technology draws on its own research. That research includes BARRED, a method for generating synthetic training data for custom small language models that was accepted at ICML 2026. Plurai says other research demonstrated how to serve hundreds of tailored small models in real time on a single GPU.
