David entered the energy sector in 2009, founding a corporate finance business specialising in renewable energy projects. He undertook project development in utility scale solar PV and wind. Latterly, he enjoyed 5 years with Jabil as a Vice President with a leading role in corporate venturing in distributed commercial energy technologies. He led a team rolling-out an innovative energy savings process across Jabil’s factories globally. In that role, he identified the issues preventing listed companies from more widely adopting energy-savings opportunities and sustainability measures, which has been a key learning in On-Site Energy’s business model. He qualified as a Chartered Accountant in 1989, and was a partner in Kidsons Impey (now RSM) for 5 years.
