StrongestLayer is an AI-native cybersecurity company building email security and human risk solutions for the era of generative-AI-powered attacks. Its proprietary TRACE (Threat Reasoning AI Correlation Engine) orchestrates multiple AI engines to replicate the analytical capabilities of more than 1,000 security analysts, shifting email defense from pattern-matching to reasoning-based detection. The platform identifies sophisticated, personalized spear-phishing campaigns that evade legacy tools — and has already detected and neutralized millions of fake company websites used in phishing operations. Founded in 2024 and headquartered in San Francisco, StrongestLayer emerged from stealth in July 2025 with $5.2M in seed funding.
