Inspired by pop culture and graffiti (not to mention pizza, cats, and explosions), artist Franky Aguilar and his app-development company 99centbrains have brought the world several popular sticker apps (such as Catwang, WayCooler, Snoopify, and CybrFM)—apps that let people manipulate and add cartoon elements to their digital photos.

He released his first app, Catwang, in April 2012. A month later, the app had been downloaded 130,000 times. Two months after that, the app (which is free but offers premium stickers for sale) was bringing in $400 a day—so Franky left a steady gig at Zynga to focus on his own creations.
