Experience

  • Co-Founder, Chief Commercial Officer at Copia Energy
    Jun 2025 - Present · 1 yr 1 mo

    Copia Energy is a new kind of battery company. We're on a mission to be the fastest to deploy 1 GWh of distributed BESS across Europe (equivalent to around 15,000 EVs ⚡️⚡️⚡️). The bottleneck in European battery deployment isn't the technology. It isn't the economics. It's execution speed. We built Copia to fix that. Our deployment model is designed to move faster than the industry currently thinks is possible, starting with the sites that keep the grid running, keep communities connected, and keep critical services online. We spent our first year stress-testing every assumption and building the integrations and partnerships required to deploy, deploy, deploy. Factory workshops across China. Commercial conversations with optimisers, aggregators, installers, utilities, and infrastructure investors across every major European market. Top-15 at Free Electrons 2025. Backed by Moonstone VC and a roster of industry angels. Active across Ireland, Austria, Italy, and the UK.
