Jonathan DiVincenzo

Jonathan DiVincenzo is the CEO and Co-Founder of Impart Security, a San Francisco-based AI-native runtime protection platform for applications, APIs, and LLM workloads. A veteran of Signal Sciences - where he served as VP of Product through the company's $825M acquisition by Fastly - DiVincenzo founded Impart in 2021 alongside Marc Harrison and Brian Joe to tackle what they saw as the broken 'last mile' of application security. His platform has deployed over 2,400 security rules across enterprise customers, cutting deployment time from 18 days to 45 minutes. In June 2025, Impart raised a $12M Series A led by Madrona Ventures.
