Joe McDonald is a serial founder with over 12 years of experience in the energy sector. After being turned down by Google for not being considered ‘Google material,’ he started his entrepreneurial journey by becoming a founding employee at energy startup Limejump.

As former Vice President of Sales and Product at Limejump, he led the development of virtual power plants that allow small, renewable energy assets to access the market opportunities of larger utilities and steered the company’s successful exit to Shell in 2019, earning him a spot on Forbes' 30 Under 30 Europe list.

Motivated by the inefficiencies in energy market transactions and a belief that energy should be a human right, he co-founded tem. in 2021 to reimagine the entire transactions infrastructure of energy. The platform uses a matching algorithm to make the way we buy and sell energy more transparent, decentralised, simpler and a fairer deal for all.
