We have been backing the ambitions of British business since 1981, supporting the aspirations of almost 550 small and mid-sized companies that form the backbone of the UK economy.

To mark this milestone, and to celebrate these unsung heroes, over the coming months we will be sharing a collection of interviews, success stories and videos. We are also partnering with the Daily Telegraph to identify 35 of the most ambitious businesses across the UK, in our 35th year.

Whilst each story is as unique as the next, it is ambition – a determination in times of opportunity and a courage in times of challenge – which unites them all.
