"Karri is a global first and a brilliant solution that eliminates the inconvenience of school payments. Karri relies on its ability to communicate with parents. “Because SMS messages are delivered directly to their mobile phones, parents are able to navigate the download process and installation process with ease, and with a far higher success rate.” Clickatell’s APIs quickly and easily allowed us to “fire off an SMS from anywhere in our tech stack, making it very easy to develop it into applications."

Louis Buys, Founder
