Secret of I Love Coffee's success: Only hires deaf baristas.

Gary Hopkins tells me the difference between social entrepreneurs and their vanilla alternatives is that they measure success in terms of jobs created rather than profit generated. And by that measure, Hopkins's mushrooming I Love Coffee enterprise is roaring. After popping into the nearby offices of DeafSA one day, Hopkins decided to focus his efforts on building a business to help the hearing-impaired, creating a company which only employs the deaf. We met at the ABSA Dome at WEF Africa where one of the special baristas, Thuliswa (pictured) delivered a decaf cappuccino as good as any I've ever tasted. Prepare to be inspired. - Alec Hogg
