Pi Security

About

Pi Security, legally registered as Nebari AI Ltd., is an enterprise cybersecurity company specializing in agentic product security. Founded in 2025 by Microsoft and Tesla security veterans Guy Arazi and Yoni Ramon, the company is headquartered in San Francisco, California. Pi Security addresses the challenges of modern software development lifecycles (SDLC), where the rapid adoption of artificial intelligence in code generation has significantly increased the volume and velocity of software vulnerabilities, outpacing the capacity of human security teams. The company's core offering is its Agentic Product Security Platform, which is designed to integrate directly into developer workflows, including integrated development environments (IDEs) and pull requests. Rather than relying solely on traditional static or dynamic code scanners that often generate high volumes of false positives, Pi Security utilizes an artificial intelligence-driven 'security brain.' This system establishes institutional memory by continuously ingesting an organization's codebases, cloud infrastructure configurations, design documentation, communication channels (such as Slack and Microsoft Teams), and historical security incident data. By contextualizing vulnerabilities within the specific development environment, the platform distinguishes high-risk issues from false positives. It autonomously generates and deploys precise remediation fixes across the software development lifecycle, from initial design to production. Additionally, when a vulnerability is resolved, the platform automatically converts the underlying pattern into a persistent guardrail, preventing similar coding errors from being reintroduced by other developers or AI coding agents. Pi Security operates on a business-to-business (B2B) subscription model, offering annual contracts that include continuous platform updates and technical support. In June 2026, the company secured $35 million in Series A funding led by Brightmind Partners and Third Point Ventures, valuing the company at approximately $100 million post-money. The capital is designated for expanding platform capabilities and accelerating global market expansion.
