Which are the most important UK companies? Is there one segment that contributes proportionately more than any other? Why are we so obsessed with the FTSE 100 and startups?

In 2014, as editor-in-chief at DueDil and working with Investec and The Times, I helped to launch the first Investec Mid-Market programme, which:

1. Identified and ranked the fastest-growing UK mid-sized companies, the Investec Mid-Market 100.
2. Created the first ever index of the ongoing health and performance of the UK mid-market, the Investec Mid-Market Index.
3. Held the first ever Investec Mid-market Summit (which I also chaired), featuring Dunnhumby co-founder Edwina Dunn, serial entrepreneur Sherry Coutu and victorious Ryder Cup captain Paul Macginley.
