Pi Security is defining a new category, Zero Recurrence Code Security, built on the premise that the industry no longer has a vulnerability discovery problem but a vulnerability recurrence problem. Rather than generating more findings, Pi learns how an organization builds, breaks, fixes, and secures software, then turns that institutional security knowledge into preventative guardrails enforced across the software development lifecycle at design time, IDE time, and pull request time. The platform ingests context from prior incidents, tickets, pull requests, repositories, architecture decisions, and developer workflows to drive root cause analysis, variant discovery, contextual remediation, and ownership mapping, becoming a living security intelligence layer for developers, AI coding agents, and security teams. Founded by Guy Arazi, an offensive security operator with roots at Palo Alto Networks and Microsoft, and Yonatan Ramon, who built safety-critical systems at Tesla, Pi raised a $35 million Series A alongside Third Point Ventures and angels including George Kurtz, Yevgeny Dibrov, and Nadir Izrael. Brightmind led Pi's Seed round in early 2025 and is continuing its support through the Series A.
