Cybersecurity Funding RevEng.AI Raises $15 Million to Hunt for Flaws and Backdoors in Software Binaries Using an AI model called BinNet, RevEng hunts vulnerabilities and backdoors in released software binaries. By Ionut Arghire | May 27, 2026 (7:52 AM ET) Flipboard Reddit Whatsapp Whatsapp Email Cybersecurity startup RevEng.AI today announced raising $15 million in a Series A funding round that brings the total raised by the company to $19.5 million. The investment round was led by NATO Innovation Fund, with additional support from Sands Capital, In-Q-Tel (IQT), IQ Capital, and Episode One. Founded in 2023, London-based RevEng.AI is using an AI model named BinNet to analyze compiled software at the binary level and identify vulnerabilities and backdoors. Unlike other solutions, the startup’s platform does not require access to source code to analyze executables, firmware, and third-party software and determine their contents. According to RevEng, the AI model has been trained with elite cyber units across allied government and commercial organizations to perform automated binary analysis. The solution can uncover hidden functionality and components, dangerous behaviors, security defects, and abnormal release changes. RevEng plans to use the technology to secure the software supply chain, which has become the prime target for attacks in the context of a surge in AI coding agent use for autonomous software development.

The solution integrates with existing security and software delivery workflows to perform proactive verification of closed-source, internally developed, and third-party software. “In a world where AI increasingly writes the code, the only universal source of truth is the executable binary files that actually run on machines,” said RevEng founder and CEO James Patrick-Evans. “RevEng gives organizations an independent way to verify software at the binary level before it is released, bought, or deployed. This is critical because much of the software being built today is never reviewed or seen by a human, making it untrustworthy,” Patrick-Evans added.
