What Artemis Does
Artemis is an AI-native security operations platform built to detect and respond to threats faster than traditional SIEMs. It continuously adapts detections to each environment, correlates signals across identity, cloud, endpoint, network, and SaaS telemetry, and lets analysts hunt threats in natural language without query syntax. Its agents perform autonomous investigation, map assets and business context, and respond to threats in hours rather than weeks, with full attack-chain visualization and contextualized cases.
The platform is designed for a landscape where AI-driven attacks unfold in minutes, using AI to defend against AI and dramatically reducing mean time to detect and respond.
Funding & Team
Founded by Shachar Hirshberg, who led product for AWS GuardDuty, and Dan Shiebler, who previously led ML and AI at Abnormal AI, Artemis emerged from stealth in April 2026 with $70M in combined seed and Series A funding. The Series A was led by Felicis with First Round Capital and Brightmind, joined by Theory VC, Two Sigma, and Lockstep, plus executives from CrowdStrike, Palo Alto Networks, Microsoft, and Okta. Artemis is headquartered in New York City.
