About
HiddenLayer is an AI security company founded in 2022 that raised $50M in Series A funding to protect machine learning models from adversarial attacks and exploitation. The platform sits between AI models and the inputs they receive, monitoring for adversarial examples, prompt injection attacks, model inversion attempts, and evasion techniques designed to manipulate model outputs. HiddenLayer also protects against model theft through model extraction detection and intellectual property protection controls that alert teams when adversaries attempt to clone proprietary models. The platform is model-agnostic and integrates with existing ML infrastructure without requiring changes to model architectures or inference pipelines. HiddenLayer serves enterprises in financial services, defense, and technology sectors where AI models process sensitive data or make high-stakes decisions. The company's security research team regularly publishes findings on novel AI attack techniques, building credibility as a thought leader in AI security alongside its commercial platform.

About
Seal Security is a Tel Aviv, Israel-based open source vulnerability patching platform — backed by Y Combinator (W20) with $20 million in total funding from MORE Investment House, SBI Insurance Group, Crew Capital, Cyber Club London, and PayPal Alumni Fund — providing development and security teams with standalone, production-ready security patches for open source software vulnerabilities that fix critical CVEs without requiring version upgrades or introducing breaking changes to application dependencies, Linux systems, and container-based images. Founded in 2020, Seal Security enables organizations to remediate critical vulnerabilities quickly — decoupling the security fix from the broader version update that typically breaks downstream functionality and triggers weeks of regression testing.
