Workforce AI security startup Harmonic Security has announced a $50 million Series B funding round, bringing the company’s total funding to $76 million.
Founded in 2023 by Alastair Paterson (CEO) and Bryan Woolgar-O’Neil (CTO), who previously founded Digital Shadows (acquired by ReliaQuest), Harmony Create a platform that secures AI tools for employees.
The solution encompasses browser-based AI, desktop AI tools, and agent workflows to categorize all AI tasks, define their usage, and provide real-time control.
Harmonic’s extended coverage exposes risks such as the use of private accounts and the disclosure of sensitive information, etc.
The startup uses a small language model to read each AI interaction in context, enabling organizations to categorize tasks, understand emerging use cases, and apply controls.
Harmonic’s Usage Intelligence layer, which provides visibility into AI use cases that create value and improve employee workflows, uses the same engine.
The fresh investment round was led by Crosspoint Capital Partners, with additional support from existing investors, and will help Harmonic expand its engineering team and go to market in the US and UK.
“Every panel I talk to is asking two questions: How do we reduce the risk of using AI, and how do we get value? Most vendors try to answer the first question, but we solve both. From the beginning, we have doubled down on our small language model, which means that we can benefit from a unique understanding of the use of AI in the enterprise,” said Paterson.
