AI agent simulation platform Plurai completes $13 million seed round financing

AI agent simulation platform Plurai has raised $13 million in a seed round led by Team8, with participation from U&I, Velocity and Mercer. The company uses synthetic data from enterprises' digital systems to simulate agent behavior, creating digital twins of knowledge bases and callable tools to map execution paths and catch potential failures in complex edge cases. Co-founder Ilan Kadar said Plurai also plans to use the data it collects to post-train open-weight small models tailored to individual customers. The raise signals continued investor appetite for infrastructure that stress-tests AI agents before deployment, rather than only funding the models themselves. Next to watch is whether Plurai converts its simulation data into a differentiated post-training offering that can compete with larger model providers.
