Simone Eyles' smartphone application 365Cups, launched in 2011, is now used by 50,000 coffee lovers across the world.

“That’s 50,000 people that have downloaded the app,” Ms Eyles said. “We’ve had 1.4 million orders … that’s more than $10 million for our clients.”

The “mumpreneur’s” simple idea of ordering coffee on a smartphone began at her “kitchen bench”, alongside her friend and business partner, Mars Stankiewicz. 

“We used to be dragging my son around with us everywhere and people were very understanding,” she said. “You can work from the kitchen bench and have a little one.”

The milestone celebration comes as more stay-at-home parents are jumping on the small-business bandwagon, achieving dreams from the comfort of home. 

“It’s surreal now, to look back,” she said. “I’ve been around the world ... It’s amazing.”

To others, Ms Eyles said small-businesses didn’t have to come from “big, fancy ideas”. She said it could be as simple as fixing a small problem that’s been bugging you. 

“It’s actually a really simple,” Ms Eyles said. “Find a solution and turn it into a business that takes you around the world.”
