Artemis emerged from stealth with $70 million in combined seed and Series A funding, positioning itself to address a rapidly evolving threat landscape driven by AI-powered cyberattacks.
The Series A round was led by Felicis, with participation from prior investors and cybersecurity industry leaders. The funding comes just six months after the company’s founding, underscoring strong early demand for its platform and the urgency of its mission.
Artemis is designed to replace traditional, rule-based security detection systems with an adaptive, AI-native approach capable of operating at machine speed. As cyberattacks increasingly leverage artificial intelligence to evolve in real time and evade static defenses, the company aims to provide enterprises with automated detection and response capabilities that match the speed and sophistication of modern threats.
At the core of Artemis is a proprietary dynamic data model that integrates behavioral log data across users, machines, cloud environments, and applications, enriched with business context. This enables the platform to understand what constitutes normal activity within a specific organization and identify anomalies with greater precision.
Rather than generating fragmented alerts, Artemis correlates signals across systems to produce unified attack narratives, reducing the need for manual investigation. The platform also enables automated response actions, such as isolating compromised identities, allowing organizations to contain threats before they spread.
The company is already deployed in production environments, processing billions of events per hour for enterprise customers across industries including technology and financial services. Early deployments have demonstrated significant efficiency gains, including substantial reductions in investigation times and improved visibility into previously undetected risks.
Artemis also differentiates itself with a federated data approach that retrieves information on demand from existing customer systems, avoiding the need for costly data ingestion and storage while maintaining full visibility.
The new capital will be used to expand Artemis’s engineering, research, and go-to-market teams, as well as to further develop its platform as enterprise adoption accelerates.
KEY QUOTES:
“We built Artemis as an AI-native defense system from the ground up. The question isn’t whether this model wins, but who builds it best. Some of the largest and fastest-growing companies in the world are among our first customers, and we’re able to deliver value to them on day one. That trust matters, and we intend to earn it every day.”
Shachar Hirshberg, Co-Founder And CEO, Artemis
“At the core of Artemis is a data model I’ve been iterating on for years. The real breakthrough isn’t just using better AI models, but in giving those models deep, structured understanding of how an organization functions, making reliable detection and automated response possible.”
Dan Shiebler, Co-Founder And CTO, Artemis
“Artemis has built a truly world-class team with rare depth at the intersection of AI and cybersecurity, solving a problem that’s becoming increasingly urgent as attacks grow in frequency and complexity. Shachar’s track record in building enterprise-scale security products and Dan’s deep AI research background make them uniquely suited to tackle this problem together. Just six months after founding and while still in stealth, the team has seen enterprise inbound driven purely by word of mouth and early results. That level of demand at this stage is rare and signals the scale of the opportunity.”
Jake Storm, General Partner, Felicis
“Having led the Humio acquisition at CrowdStrike that became the basis for their Next-Gen SIEM, I’ve seen exactly what it takes to disrupt large markets. I’ve heard the demand for a modern, highly complementary protection platform first-hand from the world’s largest enterprises, and have a clear view that this is where the market is heading. AI-powered attacks require a fundamentally new approach to defense with AI at the foundation, and Artemis is building exactly that. We co-led the seed and doubled down in the Series A because of our core belief that Artemis is building something that others simply can’t.”
