Humanix

Humanix builds what it calls a Human Threat Detection and Response (HTDR) platform: conversational AI, trained on cognitive-psychology models of manipulation, that monitors live voice, chat, email, and service-desk interactions to flag social engineering in progress rather than after the fact. The system looks for patterns such as urgency and pressure tactics, authority impersonation, identity-verification failures, and policy-evasion language, then surfaces context-aware remediation guidance to security teams.

The company’s stated differentiator is timing: most human-layer security spending goes to phishing simulations and awareness training that address behavior before or after an incident, while Humanix positions itself as detecting and interrupting manipulation as a conversation happens. Founder Keith Stewart, a security industry veteran and former interim CEO of vArmour, has argued that most major breaches trace back to interactive social engineering rather than purely technical exploits.

Humanix is based in San Francisco, was founded around 2023-2024, and has raised a combined $18 million across seed and Series A rounds led by BoldStart Ventures and Acrew Capital, with Evolution Equity Partners also participating. It was named a top-10 finalist for the RSAC 2026 Conference Innovation Sandbox contest, presenting in March 2026. No independently verified customer case studies or third-party efficacy tests were found at time of writing; claims about detection performance come from the company itself.
