Mark Hodgson

I specialise on the innovation and proposition development of new commercially driven circular and sharing business models. My background is business development, technology and markets having worked for international companies to local SMEs. My circular business journey started when studying my MBA and working with Ray Anderson who was CEO of Interface in 2002. I’m also director of Co-cars ltd, the largest SW car sharing club and Co-bikes the UK’s first on-street electric bike hire network. When not thinking about work, I travel, cycle and walk anywhere.

I’ve provided models for FTSE 100 companies to start-up business. My background is as a Certified Chartered Accountant since 2003 having worked on up to £1bn projects.
