Toni Riffel, the coffee guy, and Sarah O'Brien, the pastry lover, didn't know each other before they came together to share this space in Atlanta's Grant Park neighborhood.
"We have to split our bills, we have to split the cleaning duties. It's just like having a roommate, you know, without the chore chart," she says.
When it works, it works well — but not everything is perfect. In O'Brien's space, for example, customers have to do two transactions if they want a coffee from Octane and a croissant from her shop.
But those hang-ups aren't stopping other businesses from trying out the concept. The service Storefront matches people wanting to sell things with available space — and owner Erik Eliason says it's grown 500 percent each year since it started in 2012.
