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 publish independent energy analysis, and work on 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 hardware engineering basic training at Cambridge Consultants.
My energy analysis has appeared in The Economist, The FT, The Times, and more. My goofy projects have appeared in 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.
