Mate Security Raises $35 Million Series A to Expand AI-Powered Cybersecurity Platform

This funding comes just eight months after Mate Security launched publicly with a $15.5 million Seed round. With the new investment, the company has now raised more than $50 million in total funding.

“When we started Mate, we knew we had to invest in the foundation: context and trust, and build them deeply into our product,” said Asaf Wiener, CEO and Co-Founder of Mate Security. “We brought in some of the best AI builders and security experts, and I’m excited to see how well this approach is being received by the market. We will continue moving fast and stay laser-focused on our customers, as we expand into new markets and categories to build the Open Security Operations foundation of the future.”

“AI is forcing a fundamental rethink of security operations. What stood out to us about Mate wasn't simply its use of AI; it was the team's conviction that trustworthy AI requires a deep understanding of how an organization operates," said Joydeep Bhattacharyya, General Partner at Canaan. “By building a shared context layer that gives AI agents that understanding, Mate has taken a fundamentally different approach to security operations. The customer feedback and success we've seen in competitive evaluations reinforce our belief that the team is solving an important problem in a differentiated way.”

Founded in 2025 by Asaf Wiener, Oren Saban, and Guy Pergal, Mate Security is a cybersecurity startup that helps businesses keep their employees safe from online threats using AI-powered security tools. It protects against common cyber risks such as phishing emails, stolen passwords, harmful websites and other online scams.

The company's platform works across employees' devices and web browsers to detect and block threats in real time. This helps businesses stay secure without making everyday work more difficult.

Founded by experienced cybersecurity experts, Mate Security aims to simplify business security and reduce the risk of human mistakes, which are one of the most common causes of cyberattacks.
