About
Pi is an agentic AI cybersecurity startup, dual-headquartered in San Francisco and Tel Aviv, that automates software security from design through deployment 123. The platform analyzes source code, cloud infrastructure, and workplace communications (Slack, Teams) to identify genuine vulnerabilities while filtering false positives, then contextualizes findings using design documents, incident histories, and organizational knowledge 3. Pi was founded in 2025 by CEO Guy Arazi (a former Microsoft security researcher) and CPO Yoni Ramon (who led offensive security at Tesla for more than a decade); the company has roughly 23 employees 23. Customers include a leading AI lab, cybersecurity vendors, a major social network, and travel and insurance leaders 1.

What Founders Say
CEO Guy Arazi said: “Quick remediation is a global security problem in urgent need of a solution.” 1
Arazi also said: “Models like Anthropic’s Claude-Mythos can now uncover security flaws at a scale no human team can match, but that’s only half the equation for defenders.” 3
