After getting a quarterly power bill of more than $4000, Jennifer Rowles was ready to change providers.
Ms Rowles and her husband have been running BarLissimo, a cafe, food store and catering business, in Gwynneville for the past 12 months.
The cafe's energy bills had climbed steadily, with the last straw being that $4000-plus bill.
"Being a small business, you've got a lot of other costs that are continually going up as well," Ms Rowles said.
"I thought, how do you absorb that cost into a coffee? You can't - everyone wants their coffee to be low price. You find it hard to absorb those extra costs."
When Ms Rowles heard about Foxie she was definitely keen to see if Adam von Einem's company could save her some money.
She became Foxie's first customer and managed to save about $560 on the latest quarterly bill and about $2000 a year.
That extra money will make a difference to the business.
"It's more stock you can buy and sell and make more money off," she said. "It could be a piece of new equipment that I could buy; I could use it for an advertising budget. There are so many things that I could use that $2000 for."
