Since then, Wartman says, business at Rosa's has been picking up steam.

His email update four months later had us smiling ear-to-ear:

"It has been more than three months since you posted our story on Upworthy. It's been a CRAZY past couple months, but the business is both making more money and helping WAY more people than ever before."
—Mason Wartman

As of June 2015...

Rosa's has given away more than 23,000 slices (a 130% increase in just four months!) and is providing meals free of charge to up to 100 people on any given day.

The uptick in business means Wartman needs more employees. And true to Rosa's pay-it-forward spirit, he's hiring through agencies that connect homeless folks with jobs.

And they've even started selling official Rosa's apparel, which features designs by homeless artists. Half of all the revenue goes right back to supporting Philly's homeless community through pay-it-forward pizza. So far, T-shirt sales have funded a full 10% of donated slices.
