Israeli Startup Plurai Develops AI Agent Testing Platform

Israeli startup Plurai has developed a platform designed to rigorously test AI agents by simulating thousands of virtual customers attempting to exploit vulnerabilities and disrupt their operations. These AI agents are sophisticated programs that go beyond simple question-answering, engaging in tasks like processing returns, modifying bookings, and managing customer data. Each agent must adhere to numerous rules, and any errors can be costly. The challenge lies in the unpredictable interactions between these rules, making manual testing of all possible scenarios infeasible. Plurai's co-founder and CEO, Ilan Kadar, noted that AI systems often fail when encountering unforeseen difficulties. The company's approach draws inspiration from the autonomous vehicle industry, where Kadar and his partner, mathematician Elad Levy, previously worked at Nexar on systems for Waymo. Kadar highlighted that Waymo achieved customer trust by accumulating extensive simulation mileage, far exceeding real-world driving. Plurai applies a similar methodology to AI agents, creating a digital twin of an agent with its knowledge base, tools, and company rules. This digital twin is then subjected to tests by thousands of virtual customers, including those designed to deceive the agent and bypass its limitations. The platform's testing scenarios are generated using a 'rule map' that identifies commonly co-occurring rules. This allows the system to select combinations of increasing complexity without exhaustively testing every single possibility. Plurai claims this method yields test results comparable to human-curated benchmark datasets. Additionally, Plurai proposes a 'little guardian' system for real-time agent monitoring. Training this guardian requires thousands of labeled examples, which Plurai generates without human intervention by having one AI model create complex scenarios and others evaluate their suitability for testing. According to the company, this AI-trained guardian performs more accurately and cost-effectively than larger commercial models. Founded in 2025, Plurai has 12 employees in Israel and the US and has raised $13 million in seed funding.
