Magnitude Emerges From Stealth Mode With $10 Million in Funding

Cybersecurity startup Magnitude today emerged from stealth mode with $10 million raised in a seed funding round led by Ballistic Ventures. The San Francisco-based company seeks to enhance third-party risk management (TPRM) through an autonomous AI workforce that continuously assesses vendor risks and governs AI agents across third-party ecosystems. The rapid evolution of products, AI agents, downstream dependencies, and vendors in the Mythos era requires a faster, scalable TPRM approach that can keep up, Magnitude says. The startup’s AI risk agents gather and validate data to make risk decisions and resolve issues, and improve their reasoning in time, creating an autonomous defense system. When a new vulnerability is discovered, the agents identify potentially exposed vendors, products, agents, and dependencies, determine which vendors may be ready to respond, and prioritize actions for improved risk management. Acting as a coordinated workforce, Magnitude’s AI agents secure third- and Nth-party ecosystems, autonomously generating high-confidence decisions and remediation, and helping organizations understand their risk exposure. According to Magnitude, the solution can also help organizations adopt AI faster while ensuring they can respond to risks at the same speed as AI-powered supply chain attacks happen. “Today’s third-party risk model was built for a different era. Modern organizations rely on deeply interconnected ecosystems of vendors, products, and AI agents, creating external dependencies that traditional governance and third-party risk programs were never designed to manage continuously,” Magnitude CEO and founder Rami Habal said. “Magnitude delivers a new autonomous governance and defense system for managing third- and Nth-party risk, where assessment, monitoring, correlation, and remediation operate continuously across all external dependencies, enabling high-confidence decisions at scale,” Habal added.
