AMW Analysis
Artemis is an AI-native cybersecurity platform that automates threat detection, investigation, and response by continuously profiling telemetry across cloud, identity, endpoint, and network environments. The company emerged from stealth in April 2026, announcing a total of $70 million in funding, including a Series A round led by Felicis and a $15 million seed round co-led by First Round Capital and Brightmind. Additional institutional investors include Theory VC, Lockstep, Two Sigma Ventures, Netz Capital, and others, along with individual investments from prominent cybersecurity executives.
Artemis claims its platform uses query-first data access and automated narrative workflows to reduce mean-time-to-detect and response, lowering the operational load on security analysts. With early customers in the technology and finance sectors, the funding and launch signal growing investor interest in AI-driven security automation. The company is based in New York and targets a market increasingly focused on autonomous, multi-step attack response at machine speed.
