Serial entrepreneur Chris Koerner told Steven Bartlett on The Diary of a CEO that 90% of his business ideas can be launched with £400 ($500) or less, and none require leaving full-time employment.
Koerner, 38, has started more than 80 businesses since selling golf balls outside his home in Utah at age nine. His ventures have collectively generated low hundreds of millions in revenue and low tens of millions in profit, though the majority have failed or been abandoned.
