HiddenLayer protects AI models from adversarial attacks, model theft, and evasion techniques with a model-agnostic security layer requiring no architecture changes.
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.
AI assistant by xAI (Elon Musk); Grok 3 topped reasoning benchmarks in Feb 2025; 1M+ paying subscribers in week one; real-time X post access; distributed via X Premium; xAI valued at $24B.
Grok is the AI assistant developed by xAI, Elon Musk's AI company founded in 2023, and distributed primarily through X (formerly Twitter). Grok launched in November 2023 as an X Premium perk, with the notable differentiator of real-time access to X posts and a less restricted, more direct conversational style. Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
