John Collison, president and co-founder of Stripe, started the company with his brother, Patrick, because they were frustrated with how difficult it was to set up online payments for their previous start-ups.
"The tools and the infrastructure for building web products were getting better at a very fast rate, but when it came to running an internet business and the services available for that, entrepreneurs were really, really stuck," he told CNBC.
"They were left dealing with a 1970s banking system that hadn't been updated for the internet. There were very significant gatekeepers that kept people out of the online economy," Collison said.
This frustration is something Stripe's 25-year-old president sees as a source of inspiration for many entrepreneurs.
"I think an important force that drives entrepreneurship is a productive dissatisfaction with the way the world works. ... There are so many places where clearly a better service or a better business [could exist], or there's some opportunity to fix an inefficiency in the world," Collison said.
