Defensive AI for Cyber Threat Testing and Protection

Harmony Intelligence was founded in 2024 in Sydney, Australia and now has a strong presence in San Francisco, California. The company develops defensive AI technologies designed to protect organizations from the rapidly accelerating wave of AI-enabled cyber threats.

As generative models and autonomous tools increasingly empower attackers to craft deepfake-driven social engineering campaigns, AI-generated phishing, and automated exploitation chains, Harmony Intelligence focuses on building countermeasures capable of evolving at the same pace. The company’s core offering is an LLM-powered security agent that identifies novel vulnerabilities in web applications and APIs while dramatically reducing false positives and operational overhead. By leveraging large language models to conduct application-level assessments, Harmony Intelligence delivers deeper contextual understanding than traditional scanning methods can provide.

Harmony Intelligence raised $3 million in a March 2025 seed round led by Airtree with participation from First Row Partners, Maxwell Capital, Eric Ries (author of “The Lean Startup”), and nearly three dozen other strategic investors.
