Grant Ryan, multi-entrepreneur, the inventor of YikeBike and with four other companies behind him:
I want to emphasise a dirty little secret that some successful people don't like to mention about their start-ups. There are large elements of luck involved. To be successful, you've got to be "in the game" but if you are doing this sort of thing with any regularity, elements of luck and failure are inevitable, that's just life.
The one we had our most luck with was our first company, GlobalBrain. It was an internet search technology we founded back in 1998. It was when the internet was taking off, the first dot com boom and we struck it lucky in timing and technology.
We went from the idea to a multimillion dollar licence in a year and sold the business 12 months later to NBC's internet company. NBCI ended up tanking and the shares we got for the sale ended up worth nowhere near as much, but we learnt an awful lot.
We did a lot of the obvious things right you would expect, we got some great people involved, looked after customers well, focused on delivering, great team culture and so on. Then you have to get lucky as well. It bugs me when successful folks mention all the pretty obvious things you have to do but don't acknowledge luck.
