Bricklayer AI raises $5M to automate cybersecurity with AI agents

Bricklayer AI has secured $5 million in Series Seed funding led by Tech Square Ventures, an Atlanta-based early-stage venture capital firm, to expand its agentic cybersecurity platform that enables Security Operations Centers to deploy specialized AI agents for threat investigations and vulnerability management. The oversubscribed round positions the Arlington-based startup to capitalize on growing enterprise demand for AI-driven security automation amid chronic staffing shortages and escalating cyber threats.

The big picture: Security operations are increasingly strained by rising threat volumes and staffing shortages, creating demand for AI solutions that can handle complex multi-step tasks like threat triage and incident response with human-level context awareness.

Key growth metrics: Bricklayer AI has demonstrated explosive growth throughout 2025, expanding monthly recurring revenue more than 14x year-to-date and more than doubling in the most recent quarter alone.
• The platform is now deployed across Fortune 500 enterprises and managed security providers.
• Customers are using Bricklayer to automate thousands of analyst hours each month while maintaining human-level context.

How it works: The agentic platform enables security teams to build and orchestrate specialized AI agents that function like security analysts, handling everything from alert triage to incident response.
• AI agents can communicate and collaborate as a cohesive team to solve complex security problems.
• The system delivers scalable, auditable results with speed and accuracy that traditional automation cannot match.
• Unlike legacy automation tools, these agents work with both speed and contextual understanding.

Who else is involved: The funding round included participation from returning investors Sovereign’s Capital, Dreamit Ventures, and BlueWing Ventures.
• Bricklayer AI also joined Engage’s F500 enterprise platform as part of Cohort 15, connecting the company with 16 Fortune 500 partners including Delta Air Lines, The Coca-Cola Company, UPS, Goldman Sachs, and Georgia-Pacific.

What they’re saying: Industry leaders see Bricklayer as addressing a fundamental scaling challenge in cybersecurity operations.
• “Bricklayer is tackling one of the biggest challenges in cybersecurity today: scaling the expert decision-making of today’s cyber professionals to meet the exponentially growing threat landscape,” said Scott Lopano, Partner at Tech Square Ventures.
• “Security teams are reaching a breaking point. Legacy automation can only move so fast, but AI agents can move with both speed and understanding,” explained Adam Vincent, Founder and CEO of Bricklayer AI.

What’s next: The company plans to use the funding to accelerate product development, expand go-to-market operations, and invest in customer experience to meet growing enterprise demand for AI-driven security automation.
