TENEX, an AI-native cybersecurity company focused on transforming security operations, has raised $27m in a Series A round.
The investment was led by Crosspoint Capital Partners, with existing backers Andreessen Horowitz (a16z) and Shield Capital also taking part. Additional strategic investors are expected to be announced at a later date.
The company specialises in delivering a Managed Detection and Response (MDR) service that combines advanced agentic AI, automation and human expertise. Its platform is built natively for AI, integrating with both Google Cloud and Microsoft-based security ecosystems, and has already been deployed in high-threat environments. In just six months of operations, TENEX has surpassed $10m in revenue and signed multiple Fortune 500 and Global 2000 customers.
Funding from this round will be directed towards expanding engineering teams to advance its AI platform, scaling sales and marketing functions to capture rising demand, and strengthening customer support for its growing enterprise client base.
The business has attracted an experienced leadership team, including CEO Eric Foster, co-founder of Cyderes, and CTO Venkata Koppaka, a founding engineer of Google’s security operations stack. Other senior executives have held roles at Google Cloud, Garmin, Firemon, Cyderes, BMO, Cboe and the federal government. Recently, the firm appointed Paul Edmonds as chief customer officer to drive customer success and innovation.
Crosspoint Capital managing director Zach Sivertson said, “We believe TENEX’s unique approach of combining AI innovation with proven human expertise will deliver meaningful improvements in how enterprises detect, investigate, and respond to threats. Crosspoint is proud to back this team.”
TENEX chairman Elias “Lou” Manousos said, “In less than a year, TENEX has signed multiple Fortune 500 and Global 2000 customers, and built a cutting-edge AI platform. The company has already exceeded $10M in revenue, and scaled operations globally.
“TENEX has proven that AI and human ingenuity can create a new standard for cybersecurity resilience. This funding accelerates our momentum and cements our role as the company defining the future of Managed Detection and Response. The market is no longer asking if MDR will be transformed by AI, TENEX is proving the model others will follow.”
