Rewiring Energy: Disruption, Transparency, and Scaling with Purpose – Joe McDonald, TEM

In this energised episode, David Hunt is joined by Joe McDonald, Co-founder and CEO of TEM – a fast-scaling UK energytech startup reshaping how energy transactions are done. From his early days at LimeJump and the acquisition by Shell, to co-founding TEM and challenging the very core of how electricity is bought, sold, and valued – Joe shares a story of timing, execution, and bold ambition.

Joe and David dive into:

• The broken nature of the wholesale electricity market – and how TEM is fixing it with AI-driven infrastructure

• How scaling culture and teams in a remote-first world requires deep intentionality

• Fundraising, lucky timing, and the power of storytelling in startup success

From disrupting energy incumbents to reimagining organisational design, this is a deep and inspiring episode for cleantech entrepreneurs, investors, and energy innovators alike.
