Arianna appeared on CNBC's Squawk Box with Twitter creator Jack Dorsey to discuss his latest venture, Square.
"It's been already an amazing success and the premise is really about simplifying the complexity of credit card payments and making it cheaper for small businesses," she said.
Arianna and Dorsey discussed how both Square and Twitter have helped people find work.
"Both companies, Twitter and Square, are directly responsible for creating jobs and creating more commerce. Square specifically is something people are leaving their current work or leaving unemployment and starting something that they love, building something that they love, whether it be a food cart or a coffee store," said Dorsey.
"They are powerful platforms for job creation", Arianna said.
