Amiram Shachar is the Co-Founder and CEO of Upwind Security, a cloud-native security unicorn valued at $1.5 billion after its $250M Series B in January 2026. A serial entrepreneur with deep IDF Mamram roots, he previously founded Spot.io - sold to NetApp for $450M - before returning to build a runtime-first CNAPP platform that cuts security alert noise by 98%. He leads a team of ~350 people from San Francisco and Tel Aviv.
Ratan Tipirneni is President and CEO of Tigera, the company behind Project Calico - the open-source container networking and security project powering over 100 million containers across 8 million nodes in 166 countries. A serial entrepreneur with stints at Cisco, Actifio, Sun Microsystems, and SupportSoft, he joined Tigera in 2017 and has since grown it into the definitive platform for Kubernetes security, observability, and now AI workload protection.
Tigera is the creator of Calico, the open-source standard for Kubernetes networking and security that powers more than a million clusters every day. From its San Jose headquarters, the company sells Calico Cloud and Calico Enterprise - SaaS and on-prem platforms that bolt active runtime security, zero-trust microsegmentation, and observability onto container environments at any scale.
Upwind is a runtime-first Cloud Native Application Protection Platform (CNAPP) that unifies cloud and AI security across the full lifecycle. Founded in 2022 by the team behind Spot.io, the company uses eBPF-based runtime telemetry to give security teams real-time context on what's actually exploitable in production - cutting noise, surfacing real threats, and protecting cloud-native and AI workloads at the speed they run.
Brendan Gregg is an Australian systems performance engineer at OpenAI, where he works on datacenter optimizations for ChatGPT. He invented flame graphs and the USE Method, pioneered eBPF observability, and is the author of landmark books including 'Systems Performance: Enterprise and the Cloud'. His work is credited with saving the industry over $1 billion in compute costs. Previously an Intel Fellow and performance engineering leader at Netflix, Gregg is one of the most influential engineers in Linux and cloud infrastructure.
