Artemis is building the future of AI-driven cybersecurity, helping companies defend themselves effectively in an era where AI is fighting AI on the cyber battlefield.
Our platform brings a new approach to the $100B security operations market, building a live model of each customer’s environment and using AI agents to detect, investigate, hunt, and respond to threats at machine speed. Just one year after our founding, Artemis is one of the fastest-growing cybersecurity companies of all time, with customers including multiple Fortune 500 companies, Global 2000 enterprises, and AI innovators like Cursor.
We have raised $70M from Felicis, First Round Capital, Theory Ventures, Two Sigma Ventures, Lockstep VC and Brightmind. We are also backed by some of the most prominent operators in cybersecurity, including the CEO of Crowdstrike, the former CEO and CTO of Splunk, and the founders of Abnormal AI and Demisto.
Artemis’s founders have built and scaled security products used by tens of thousands of customers. Shachar Hirshberg (CEO) led Amazon GuardDuty, the world’s largest cloud detection product, was an early employee at Demisto, the company that invented the SOAR category, was an engineering leader at Palo Alto Networks, and holds an MBA from Harvard. Dan Shiebler (CTO) led all AI and machine learning at Abnormal AI, the pioneer of behavior-based detection, spent five years building analytics using machine learning and vector databases at Twitter, and holds a PhD in machine learning from Oxford.
Our team of software engineers, AI researchers, security engineers, and product designers comes from Google, Meta, AWS, Wiz, CrowdStrike, SentinelOne, Abnormal AI, Perplexity, Bridgewater, Mercor, CERN, and more.
We’re growing fast and looking for builders who want to help us serve our rapidly expanding customer base.
We're hiring our first MDR Lead to launch Artemis's managed detection and response function in Israel (Apollo). This is a foundational role.
You'll start as the senior hands-on operator, running investigations, tuning detections, and handling the hardest incidents yourself. You will grow the team - hire, coach, and lead analysts, and set the standards they work to. You’ll work closely with product, detection engineering, and customer success to turn what we learn in the SOC into product improvements.

Artemis is building the future of AI-driven defense - helping companies detect and defend themselves effectively in an era where AI is fighting AI on the cyber battlefield.
As an AI-native Protection Platform, Artemis reliably detects and contains important threats with actionable context. By streaming only detection-critical logs and retrieving the rest on demand in a federated manner, it reduces cost while ensuring full visibility. Because it agentically and continuously adapts to changes in your environment and the threat intelligence landscape, your detection coverage never falls behind - delivering stronger protection.
We’re backed by Felicis, First Round Capital, Brightmind, Theory VC, Lockstep, Two Sigma Ventures, and a group of the cybersecurity industry’s most prominent operators.
