TENEX.AI has announced a $250 million Series B funding round led by Crosspoint Capital Partners, positioning the company to accelerate hiring, expand internationally, and deepen investment in its AI-driven security operations platform.
The company, led by CEO Eric Foster, said the funding is intentionally focused on scaling human talent alongside artificial intelligence. The approach reflects a core belief that while attackers benefit from automation, defenders must combine AI with skilled personnel to close the gap.
Since emerging from stealth in early 2025, TENEX has grown rapidly, generating more than $25 million in contracted revenue and achieving 318 percent year over year headcount growth. The company also earned the top ranking on the 2026 Cyber 150 list, highlighting its rapid ascent in the cybersecurity sector.
TENEX’s platform is designed as AI-native from inception, rather than retrofitted with artificial intelligence. Its system processes 100 percent of customer alert telemetry in under a minute, compared to an industry norm closer to 10 percent. The company reports a greater than 95 percent reduction in false positives, enabling human analysts to focus on high-priority threats while AI handles scale and automation.
The Series B funding will be deployed across several key initiatives. TENEX plans to hire more than 250 employees across engineering, security operations, sales, and customer success roles. The company is also expanding into Europe, the Middle East, and Africa, where demand for modern security operations is increasing due to regulatory pressure and talent shortages.
Additional investments will focus on strengthening partnerships with hyperscale cloud providers, expanding integrations, and advancing threat intelligence and AI research and development. The company emphasized that its platform will continue to evolve significantly over the next year.
TENEX’s model combines AI-driven automation with human oversight, where AI triages and investigates alerts while analysts make critical decisions. This hybrid approach is positioned as a structural shift in how cybersecurity services are delivered.
The company believes the combination of funding, AI capabilities, and talent expansion marks a turning point in cybersecurity, enabling defenders to operate at a scale and speed previously unattainable.
KEY QUOTES:
“TENEX has reimagined the managed security services industry and built something differentiated: an AI-native platform with elite human expertise to protect enterprises at scale. The company stops threats with the speed needed to defend an AI-enabled advisory and is delivering that value with an excellent financial model. TENEX provides better gross margins than traditional software, where customers buy an outcome like traditional managed service offerings. With TENEX, there are no trapped resources or associated incremental headcount per customer. The financial opportunity in the AI enablement comes from the market’s underestimation of how AI can transform the value of services industries. The MDR market is massive and can now operate profitably. Crosspoint Capital is excited about this backdrop and the opportunity at TENEX.”

“We just raised $250M to hire more humans. In the AI era. On purpose. For my entire career, the bad guys have been winning. Not because defenders lack talent or the technology doesn’t exist, it’s because the math has been wrong. Attackers scale with automation and defenders scale with headcount. And headcount has never kept up. We believe we’re going to build the biggest and best security services company to ever exist, but even that isn’t the point. It’s a required step toward the objective that actually matters: making a material difference in cybercrime. This funding is a chance to put hundreds more people into the fight this year, armed with AI that makes each of them 10X more effective. AI handles the volume. Humans handle the judgment. That’s not a feature. That’s the architecture. That’s the mission.”
Eric Foster, CEO, TENEX.AI
