Josh Curl is a San Francisco–based founder and CTO with 11 years of experience building cloud-native infrastructure and developer tools. As Co-Founder & CTO of Hightouch and previously Deviceplane, he combines product-led engineering with hands-on systems work—early at Rancher where he contributed to RancherOS, Kubernetes integrations, and security hardening that supported a major exit. His open-source contributions to projects like docker/libcompose and rancher/cli show deep expertise in container tooling, configuration parsing, and practical DevOps automation. Comfortable moving between low-level OS/security work and higher-level API/product development, he has a track record of turning operational complexity into usable platforms.
