GreyNoise Built a Business by Telling Security Teams What to Ignore
Most cyber vendors sell more alarms. GreyNoise built thousands of patient decoys, learned the rhythm of indiscriminate attacks, and made a business out of the far more useful answer: not this one.
Torq Threw Out Its First Startup Idea - Then Built the AI Security Operator Big Companies Actually Use
Torq started with a product the market would not reliably buy. Its founders followed the one group already pulling it off the shelf - security teams - and turned that failed sales motion into a $1.2 billion lesson in listening.

Dropzone AI
Dropzone AI builds an autonomous AI SOC analyst that investigates 100% of security alerts around the clock, mimicking the reasoning of an expert human analyst across phishing, endpoint, network, cloud, identity, and insider-threat domains. Founded in 2022 by former ExtraHop AI lead Edward Wu, the Seattle company replaces playbook-driven busywork with end-to-end investigations and high-fidelity reports, letting overwhelmed security teams focus on real threats. It has raised $57.35M to date, including a $37M Series B in July 2025.
Edward Wu
Edward Wu is the founder and CEO of Dropzone AI, a Seattle company building autonomous AI agents that investigate security alerts like a tier-1 SOC analyst. After eight years at ExtraHop Networks leading AI/ML detection engineering and dropping out of a computer science Ph.D. at the University of Washington, he started Dropzone in 2023 to attack what he calls the defender's dilemma. The company raised a $37 million Series B in July 2025 led by Theory Ventures, serves more than 100 enterprises, and counts UiPath, Zapier and Pipe among its customers. Wu holds more than 30 patents in machine learning and cybersecurity and contributes to the MITRE ATT&CK framework.
SentinelOne
SentinelOne is an American cybersecurity company that builds the AI-powered Singularity Platform, autonomous software that detects, hunts, and responds to attacks across endpoints, cloud, identity, and data in real time. Founded in 2013 and headquartered in Mountain View, California, it pioneered machine-learning-driven endpoint protection that works without human intervention and now competes head-to-head with CrowdStrike and Microsoft in the enterprise security market. After the largest cybersecurity IPO in history in 2021, the company crossed $1 billion in annual recurring revenue in 2025.
Simbian
Simbian is a Mountain View startup building autonomous, self-improving AI agents for security operations. Its platform pairs a Context Lake of institutional knowledge with TrustedLLM-powered agents that triage alerts, hunt threats, run pentests, and manage firewalls 24/7 — built to counter AI-powered attacks that move faster than humans can react.
Ambuj Kumar
Ambuj Kumar is the co-founder and CEO of Simbian, an AI-native security company building autonomous AI agents that run security operations 10x faster than human teams. A Gold Medalist from IIT Kanpur and Stanford EE graduate, he spent eight years designing NVIDIA's early GPUs before pivoting to security - where he invented Confidential Computing, raised $135M for Fortanix, and is now betting that AI agents can solve the industry's 3.5-million-person talent gap. With 100+ patents and recognition from IIT Kanpur's Distinguished Alumni Award 2025, Kumar stands at the intersection of the GPU revolution he helped build and the AI security era he is now shaping.
