Artemis, founded in 2025 and based in New York, is an AI-native security platform delivering real-time detection and automated response, positioned as a SIEM replacement built for AI-speed attacks and replacing alert-driven triage with autonomous investigation.
It emerged from stealth with a $70 million combined seed and Series A only six months after founding, with investors including the founders of Demisto and Abnormal AI and senior executives from CrowdStrike, Palo Alto Networks, Microsoft, and Okta. Its claimed 94% response-time reduction is vendor-reported.
Innovation Matrix Assessment
Raised $70M combined seed ($15M) and Series A ($55M, announced 2026-04-15) just six months after founding, an unusually fast and large capital velocity.
About 30 employees at launch with plans to reach ~65 by end of 2026; named enterprise production deployments were not disclosed in coverage reviewed.
Series A led by Felicis (with First Round Capital and Brightmind increasing stakes) closed 2026-04-15, joined by the founders of Demisto and Abnormal AI and senior CrowdStrike/Palo Alto Networks/Microsoft/Okta executives.
Positions itself as a full SIEM replacement built around autonomous investigation rather than alert triage, a meaningful architectural shift if it holds up at scale.
The cited 94% response-time reduction is self-reported by the company; no independent benchmark was located.
Machine-speed, AI-powered attacks are a rapidly growing concern, making real-time autonomous detection and response highly relevant.
Why CISOs Should Care
Artemis is an AI-native security platform delivering real-time detection and automated response, positioned as a SIEM replacement built for a threat landscape where AI-powered attacks move at machine speed, replacing alert-driven triage with autonomous investigation.
What Makes It Different
Emerged from stealth with an unusually large $70M combined seed/Series A only six months after founding, with the round joined by the founders of Demisto and Abnormal AI and senior CrowdStrike, Palo Alto Networks, Microsoft, and Okta executives as investors -- a strong industry-insider signal.
The Matrix Verdict
53/100 — INCREMENTAL INNOVATOR
Exceptionally well-capitalized and operator-endorsed SecOps platform for an early-stage company; the claimed 94% response-time reduction is a notable but vendor-reported figure to watch for independent validation.
Editorial Note: Claims vs. Verified Findings
Funding, investor identities, and headcount verified via Calcalistech, GovInfoSecurity, and AlleyWatch. The '94% faster response' claim is company-reported and not independently benchmarked.
