Overview
Plurai offers a platform designed to improve AI agents by identifying failures through simulation and enhancing model performance. Its simulation engine maps an agent's structure, mocks its environment—including tools, sub-agents, and knowledge sources—to identify bugs and verification fixes within real workflows. Additionally, the company provides post-training services that allow users to refine open-source models, aiming to increase accuracy and reduce inference costs. Plurai's solutions are used by enterprises to build and deploy custom small language models (SLMs) and guardrails for production environments. The company operates on a subscription-based model with tiered pricing plans and usage-based billing. Founded by researchers and engineers, the company has raised $13 million in seed funding. The team actively maintains a research blog and participates in the broader development of AI evaluation and agentic workflows.
