TENEX, an AI-native cybersecurity company, has raised $27m in a Series A round.
The funding was led by Crosspoint Capital Partners, with backing from Andreessen Horowitz (a16z) and Shield Capital. Additional strategic investors are expected to be disclosed later.
The company provides a Managed Detection and Response (MDR) service that combines agentic AI, automation and human oversight. Its platform is designed to integrate with Google Cloud and Microsoft systems, delivering rapid detection, accurate triage and autonomous responses. Within six months, TENEX has surpassed $10m in revenue and signed up multiple Fortune 500 and Global 2000 customers.
The new funds will be used to grow engineering teams, expand sales and marketing operations, and enhance customer support as demand for its services increases.
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.”
