Reach Security, founded in 2021 and headquartered in San Francisco and Sunnyvale, California, closed a Series B round of more than $50 million on October 13, 2026. The round was led by Top Tier Capital Partners and included Ballistic Ventures, In-Q-Tel, Microsoft’s M12 fund, and prior backers. Total capital raised now surpasses $80 million after an approximately $20 million Series A in 2024 and follow-on investment in 2025.
Funding Details and Investor Backing
The new capital will support product development, expanded partner integrations, and growth in U.S. enterprise and federal markets. Reach Security has already doubled its customer base over the past twelve months, with named clients including Autodesk, Insurity, MPS, and Ensemble Health Partners. The company focuses on organizations that need continuous validation of existing security tools rather than additional point products.
Top Tier Capital Partners partner Garth Timoll described the platform as a critical layer in the emerging AI security stack. Autodesk security leader Sebastian Goodwin called Reach Security the organization’s source of truth for control effectiveness. CEO Garrett Hamilton stated that accurate, machine-speed understanding of controls gives defenders a measurable advantage against automated attacks.
Independent data cited in the announcement underscores the urgency. CrowdStrike’s 2026 Global Threat Report recorded an 89 percent increase in AI-enabled adversary activity, with some intrusions completing in as little as 27 seconds. VulnCheck analysis showed that fewer than 1.3 percent of known vulnerabilities are actively exploited, highlighting the need to focus on reachable attack paths rather than volume of alerts.
Platform Capabilities and Reach Everywhere Launch
Alongside the funding, Reach Security released Reach Everywhere, which exposes its deterministic AI insights through APIs, MCP servers, and partner integrations. The offering connects directly to exposure management, security operations centers, incident response workflows, compliance systems, and emerging AI security tools. Enterprises can now embed Reach’s analysis of reachable exploit paths and protection drift into existing platforms without replacing current investments.
The core platform continuously discovers, validates, and optimizes security controls across an organization’s tool stack. It identifies specific rules that block or allow given attack techniques and remediates gaps that arise from configuration changes. An independent TAG Infosphere ROI study reported that users saved more than 160 hours per week and achieved a 156 percent return on investment.
Reach Security positions its approach against the rapid evolution of AI-driven threats. Rather than adding more detection layers, the system maps which existing controls are effective and which have drifted, allowing security teams to close exploitable gaps at machine speed. The company plans to extend these integrations internationally while deepening its presence in regulated U.S. sectors.
