About
Hello! I'm a technologist and writer. You might like to read my 2025 in review, or my theory of life.
Right now I work on building Virtual Power Plants at Axle Energy.
Previously, I VC'd at a couple of VCs, built Octopus Electric Vehicle's pricing platform, worked on edge deployment of AI models at Arm, wrote about tech for WIRED and Hackaday, worked on the IPCC's Sixth Assessment Report, and did my basic training in electronics at Cambridge Consultants.
My energy analysis has appeared in The Economist, The FT, and The Times. My goofy projects have been featured by the BBC and Time Out. I am lucky to have been supported by Emergent Ventures, the Centre for British Progress, EF, the Roots of Progress, and the Royal Academy of Engineering.
