Mate Security Raises $35 Million Led by Microsoft to Expand AI Cybersecurity Platform
Israeli cybersecurity startup Mate Security has secured $35 million in a Series A funding round led by Canaan Partners and Microsoft’s M12 fund, with participation from existing investors Insight Partners and Team8. This round comes just eight months after the company’s initial $15.5 million seed funding, bringing total capital raised to over $50 million. Founded in 2025 by CEO Asaf Weiner, CPO Oren Saban, and CTO Guy Pergal, Mate Security’s team includes veterans from Wiz, Axonius, Meta, Microsoft, and former Unit 8200 members, with expertise in AI and cybersecurity. The company employs 50 people, mostly in Israel, with the remainder in the US.
Mate Security’s platform addresses the challenge of defending against rapidly evolving cyberattacks in the AI era, where traditional security systems struggle to keep pace. Their open platform enables organizations, including Fortune 500 companies, to detect and respond to threats within minutes by leveraging an AI-driven "organizational brain" that contextualizes security data. This patented contextual layer integrates business knowledge to improve agent accuracy in threat detection, investigation, and response.
CEO Asaf Weiner highlighted the platform’s ability to provide high-quality AI agent investigations and adapt to changing threats, which has driven over 500% revenue growth since Q3 2025. The new funding will support scaling sales, support, and R&D teams to meet growing customer demand, particularly in the US market. The partnership with Microsoft also offers strategic collaboration and access to advanced AI models.
Mate’s technology unifies data from multiple sources into a Security Context Graph, coordinating various security agents under a central management system that enforces consistent authorization and auditing. This approach allows gradual expansion of autonomous agent actions to remediate threats while maintaining trust and control in sensitive environments. The company aims to double its workforce by year-end to support this growth trajectory.
