## Summary

Raised $70M in combined Seed and Series A in 2026 within 6 months of launch; Series A led by Felicis. Positions as "AI vs AI" autonomous defense platform.

## Company Overview

Artemis builds an autonomous AI defense platform designed to counter adversaries that are themselves operating AI agents for offense. The thesis is that as attackers adopt AI for reconnaissance, exploit generation, and lateral movement, defenders need AI systems that operate at matching speed and scale — an "AI vs AI" posture.

Within six months of launch, Artemis raised approximately $70M combined across Seed and Series A, with the Series A led by Felicis Ventures. The company exited stealth in early 2026 and has been rapidly signing enterprise pilots.

Artemis positions against legacy SOC vendors (Splunk, SentinelOne, CrowdStrike Falcon Complete) and emerging AI SOC startups (Prophet Security, Dropzone AI, Intezer, Radiant Security). Differentiation is agent-on-agent architecture — autonomous defenders that dynamically generate and execute response playbooks.
