About Humanix

Humanix Security Inc. is a cybersecurity company that focuses on protecting the "human layer" of organizations from social engineering attacks. The company was founded by CEO Keith Stewart. In November 2025, Humanix announced it had raised $18 million in a combination of Seed and Series A funding rounds. The seed round was led by BoldStart Ventures, and the Series A was led by Acrew Capital.

The company's platform utilizes AI-powered natural language analysis combined with insights from behavioral science to defend against attacks targeting personnel at help desks, service desks, and other customer-facing channels. It monitors conversations in real-time across phone, chat, and service tickets to identify manipulation tactics, impersonation, and policy violations that signal a social engineering attempt. When a potential attack is detected, the platform provides real-time intervention guidance to the employee, helping them respond appropriately and securely.

The system is designed to turn employees from a potential vulnerability into a line of defense. Beyond real-time intervention, Humanix provides assurance and documentation by tracking that correct procedures were followed, which helps organizations reduce liability, maintain customer trust, and demonstrate compliance. The business serves clients in sectors such as finance and hospitality. Humanix aims to make the human element of security visible and defensible, addressing what it considers a major blind spot in traditional cybersecurity.
