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.
