Zain Rizavi is Co-Founder and CEO of Cimento AI, an AI-native human risk management platform that builds a living risk profile for every employee to combat the growing threat of AI-powered cyberattacks.

Zain earned a B.S. in Political Science from the University of Utah, then built a rare dual career as a cybersecurity operator at Cloudflare's Special Projects Team and as a venture investor, serving as Principal at Ridge Ventures where he evaluated early-stage security startups.

Zain founded the Cloudflare Angels Network, leveraging his deep network of security operators from companies like Palo Alto Networks, CrowdStrike, Okta, and Nvidia as strategic investors in Cimento AI. His experience on both sides of the table gives him a uniquely informed perspective on what enterprise security tools get wrong.

Cimento AI emerged from stealth in May 2026, raising approximately $3 million in pre-seed funding from Bowery Capital, Indie VC, and angels from Cloudflare, Palo Alto Networks, Nvidia, and Okta. The platform is already serving enterprise customers including Together AI, targeting regulated industries and AI-native companies.

Cimento's platform replaces outdated annual training and checkbox compliance with real-time, behavior-based risk scoring, addressing a threat landscape where 68% of breaches involve a human element and the cost-per-phish has dropped 100x due to AI.
