Sam Elliott
Chief Operating Officer
London, England, United Kingdom
Summary
🤩
RockstarSam Elliott is a multidisciplinary operator and engineer with 17 years of experience combining consulting, service design, behavioural economics and hands-on compiler and embedded systems work. As a serial founder and current COO in London's beverage space, he has scaled brands and fixed operational inefficiencies for startups and household names like Soho House and NatWest. Technically, he contributes to low-level projects—work on LLVM/Clang, RISC-V support, OpenTitan firmware and the Idris language—showing deep expertise in compiler backends, ISA support and secure boot/driver code. He also maintains full-stack fluency, having improved core functionality in the widely used Bacon.js reactive library. Comfortable shifting between strategic growth, UX-led transformation and systems-level programming, he brings a rare mix of business leadership and low-level engineering rigor. A not-obvious strength: he pairs commercial go-to-market instincts with concrete contributions to open-source toolchains that underpin modern platforms.
