7AI Raises $130 Million in Record Cybersecurity Series A
Cybersecurity startup 7AI has secured $130 million in Series A funding, marking the largest such round in industry history. The investment values the company at $700 million and brings total capital raised to $166 million since its February launch from stealth. Backed by Index Ventures and Blackstone Innovations Investments, the funds target expansion of agentic AI platforms for autonomous security operations.
The round includes participation from Greylock, CRV, Spark Capital, and prior seed investors. Shardul Shah from Index Ventures joins the board, emphasizing the platform’s potential to transform enterprise threat response. 7AI’s technology deploys AI agents for alert triage, investigations, and incident response, integrating with existing detection tools without data centralization.
Over the past 10 months, 7AI agents processed 2.5 million alerts and completed 650,000 investigations across client environments. Customers report investigation times reduced from 30 minutes to 2.5 hours per case, with false positive elimination reaching 95 to 99 percent. The platform generates natural language summaries of incidents, such as identifying phishing emails with malicious PDF attachments containing links.
Founded by Cybereason co-founder Lior Div as CEO, 7AI positions itself as the first agentic security platform leveraging generative AI for cyber defense. It avoids manual data copying to centralized systems, minimizing storage costs and compliance risks. Administrators can query agents for additional actions, enabling proactive measures like threat hunting.
In August, 7AI partnered with DXC Technology, combining the provider’s operations with autonomous agents for enhanced scalability. DXC, a Fortune 500 client, deploys the platform for global security workflows. Blackstone’s chief security officer Adam Fletcher highlighted the investment for deepening product innovation and execution pace.
The funding arrives amid surging demand for AI-driven security, where enterprises face alert volumes exceeding human capacity. 7AI’s agents handle non-human tasks, freeing analysts for strategic roles. Yossi Dantes, chief product officer at Malanta.ai, described the capabilities as a major industry milestone, validating agentic AI for production use.
Plans include doubling or tripling the Boston headquarters headcount, focusing on engineering and sales. The startup serves sectors including finance and technology, with integrations supporting tools from major vendors. Revenue growth stems from subscription models tied to agent deployments and investigation volumes.
Competitors in agentic security note 7AI’s edge in runtime efficiency, processing telemetry directly at the source. The platform supports multi-cloud environments, ensuring compatibility with AWS, Azure, and Google Cloud. Early adopters achieve 40 percent faster response times compared to legacy SIEM systems.
This raise reflects investor confidence in AI’s role against evolving threats like ransomware and supply chain attacks. 7AI commits to open APIs for custom workflows, fostering ecosystem integrations. Blackstone’s involvement signals enterprise validation, with pilots expanding to 50 organizations by mid-2026.
The Series A underscores a shift toward autonomous defense, where AI agents operate at scale without supervision. 7AI’s roadmap features enhanced reasoning for complex scenarios, including lateral movement detection. Customers like DXC report 30 percent operational cost savings through reduced manual triage.
Industry analysts project agentic platforms capturing 25 percent of the $50 billion SOC market by 2028. 7AI’s valuation premium highlights its traction, with 200 percent year-over-year client growth. The funding enables R&D into quantum-resistant encryption for agent communications.
As cyber incidents rise 15 percent annually, 7AI’s model addresses analyst shortages affecting 70 percent of teams. The platform’s audit logs comply with NIST and ISO standards, aiding regulatory adherence. Future updates include voice-activated queries for on-call responders.
This investment positions 7AI to lead in AI-native security, bridging detection and response gaps. Enterprises gain verifiable outcomes, with dashboards tracking agent efficacy metrics. The startup’s Boston roots leverage regional talent pools for sustained innovation.
