After a brief time in the City, Mike grew and then sold Numicon Ltd. to Oxford University Press before launching National Numeracy as an independent charity in 2012. He co-founded Precision Hydration Ltd. in parallel with growing National Numeracy and recently launched The Plain Numbers Project, building upon an element of the research conducted within National Numeracy.

His wife, Hannah served in the Royal Army Medical Corps before becoming an osteopath and they have three teenage daughters. Mike holds the Guinness World Record for a marathon with a 20lbs pack (2h56) and he remains fit; he used the tactical pause before starting as Chief Executive of the Trust to complete the South Downs Way on a bike one way in under 7 hours and then the South Downs Double in under 16 hours, raising funds for Support Our Paras.
