This week's featured interview is with Chicago's very own, Jeff Hyman, CEO of Retrofit. Retrofit is a web-based weight loss program that combines wearables (think Fitbit), wireless scales and regular skype calls with your personal registered dietitian, exercise physiologist and behavior coach. Jeff himself, has been around the block, worth $51 million dollars before the bubble - and $51 after it burst. Jeff didn't fall easily and went on to build 2 more successful businesses (selling 2 of them) until he landed on a passion project - Retrofit. He started the business manually tracking people's weight loss using a handful of fitbits, a weight loss support team and no web or mobile app. Let's just say people liked it...and Weight Watchers is scared. This week's music feature is Chicago's own.
