Artemis Security names Arun Singh Chief Growth Officer

Artemis Security has appointed Arun Singh as Chief Growth Officer, following a year in which the cyber security company said its revenue grew more than 100-fold.

Singh joins as Artemis looks to build on rapid commercial growth in its first year of operations. In that time, the company said it went into production at large enterprises, raised USD $70 million in seed and Series A funding within six months, and shipped five products on a single platform over 12 months.

The appointment also follows Artemis being named to the Fortune Cyber 60, a list of venture-backed cyber security companies presented by Lightspeed Venture Partners and AWS in partnership with Fortune.

Singh has held roles at Salesforce, Okta, Cloudflare, Abnormal AI and Drata. Most recently, he was Chief Marketing Officer at Drata, where Artemis said he helped expand the company from compliance automation into a broader enterprise platform.

Before that, he led marketing at Abnormal AI during a period when annual recurring revenue grew more than 12-fold in three years, according to Artemis.

Chief Executive Officer and Co-Founder Shachar Hirshberg outlined the case for the hire.

"From Fortune 500 enterprises to AI-native startups, Artemis has proven that defenders can stop attacks at AI speed. Unlike most AI in security operations, which starts after an alert fires, Artemis learns each customer's environment, keeps a living model of it, and writes and tunes detections for each customer. From the same model, it hunts for threats, investigates every case and responds. In our first year, it flagged 92% of confirmed attacks at the point of entry within seconds. Arun has scaled category-defining products in large markets before. He is the right leader for our next phase of growth," said Hirshberg.

Growth push

Singh will lead Artemis's next stage of growth as it targets wider adoption among enterprise security teams. The company sells security operations software, including AI SIEM, AI SOC, AI SOAR, AI Threat Hunting and AI MDR.

According to Artemis, its customer list includes Cursor, Mercury, Lemonade, Wix, Quartermaster and an unnamed global financial institution. It said it serves dozens of Fortune 500 and Global 2000 enterprises, as well as AI-focused businesses.

The company also disclosed operating figures to show scale, saying its platform analyses hundreds of billions of security events a day and investigates more than 70,000 cases a month.

Artemis argues that the pace of AI-driven attacks has exposed the limits of older security operations tools. It said traditional SIEM products were designed for an era when analysts had hours or days to search logs and piece together incidents manually.

By contrast, Artemis said its software builds a model of each customer's environment using data from HR, identity, cloud and asset inventory systems. It then uses that model for detection, investigation and response, with actions either approved by analysts or run automatically if the customer allows it.

The company said a regulated enterprise with tens of thousands of employees cut mean time to resolution by 96%, reducing investigations from several hours to under five minutes.

Market position

Beyond the Fortune recognition, Artemis said Anthropic named it among the 10 most AI-native startups in the world, while analyst firms SACR and Latio identified it as a leader in their reports. It also said it is the only security operations startup in CrowdStrike's QuiltWorks alliance.

Artemis said it connects with more than 250 tools across identity, cloud, endpoint, SIEM, ticketing and collaboration software. In its first year, it also launched more than 8,000 features, more than 38,000 detectors, and completed 30,000 pull requests.

For Singh, the commercial opportunity lies in the mismatch between the speed of attackers and the speed of most security teams.

"Attackers now move at AI speed, while security operations still move at human speed. Artemis closes that gap by putting the defender's one lasting advantage, knowledge of their own environment, to work at the moment of detection. Enterprises are adopting it at a pace I have rarely seen in my career, and my focus now is scaling that momentum. I look forward to bringing Artemis to many more security teams," said Singh.

Customers cited by Artemis described the platform in similar terms. "At Cursor we know what great AI products look like. Artemis is the first time we have seen that same standard applied to security, detecting and responding at the speed our environment actually moves," said Tom Daniels, CISO, Cursor.

"It's like having a service working 24 hours a day that never gets tired, doing what you would normally have to hire a managed service for, with more consistency and higher quality," said Jaffe.
