upstart: [16] An upstart is etymologically simply someone who has ‘started up’ – but start in its early sense ‘jump, spring, rise’. Start-up was an early alternative version of the word (‘That young start-up hath all the glory of my overthrow’, says Don John in Shakespeare’s Much Ado About Nothing 1599), but it did not survive the 17th century.
